Optical transceiver has developed to 400G optical transceiver, and manufacturers are stepping up research and development to seize the hot spot. Many mainstream manufacturers choose QSFP-DD as the package of 400 optical transceivers, but why do 400G optical transceivers prefer QSFP-DD? Does it mean that QSFP-DD will be the main package of 400G optical transceivers in the future?

A good packaging must first support the types of transmission media and optical transceivers that are widely used in the networking industry. The transmission media include passive direct connection copper cable (DAC), multimode fiber (MMF) and single-mode fiber (SMF). Optical transceivers, active copper cables, and active optical cables include the 100Gb /s, 200Gb/s, and 400Gb/s series defined by Ethernet, Fibre Channel, and InfiniBand standards. Furthermore, the port density of the new package should be the same as that of the already deployed network. Finally, the backward compatibility of the new package with the already widely used QSFP package is critical for industry adoption. The QSFP-DD optical transceiver is a package that meets all the above conditions.

I. The development history of QSFP-DD optical transceiver

On March 21, 2016, the plan to develop QSFP-DD high-speed interface was started.

On September 19, 2016, version 1.0 of the QSFP-DD hardware specification containing the drawings was released.

On March 13, 2017, version 2.0 of the QSFP-DD hardware specification and QSFP-DD white paper were released.

On September 19, 2017, version 3.0 of the QSFP-DD hardware specification was released, along with the CS Connector specification

On March 13, 2018, the QSFP-DD Thermal Design White Paper was released, addressing the issue of how to evaluate the thermal performance of the QSFP-DD module in a high-performance data center environment.

On August 30, 2018, it was announced that the QSFP-DD package had successfully passed the equipment interoperability test, and the QSFP-DD package optical transceiver was now ready for official use.

On 18 September 2018, version 4.0 of the QSFP-DD hardware specification and version 3.0 of the General Management Interface Specification for 8/16 Channel Placable Optical Modular were released.

So far, QSFP-DD MSA is relatively completed, and QSFP-DD optical transceivers of leading optical transceiver manufacturers were also listed in that period.

II. The application in the research and development of 400G optical transceiver

The QSFP-DD dual-density four-channel small pluggable package is a high-speed pluggable module package defined by the QSFP-DD MSA team as the preferred package for 400G optical transceivers, enabling data centers to effectively grow and expand cloud capacity as needed.

III. Characteristics of 400G QSFP-DD optical transceiver

The compatibility of the 400G QSFP-DD optical transceiver with the QSFP solution is one of its main advantages. The original QSFP28 module can still be used; you just need to insert another module.

In conclusion, the characteristics of the QSFP-DD optical transceiver package have unparalleled advantages in 400G applications (such as data center interconnection). It is expected that the world's leading ultra-large data center will soon deploy 400G, and QSFP-DD may become the mainstream package.

AOC active optical cable is an optical fiber with a module attached to each end, which is equivalent to a cable and a module.AOC active opti

AOC (Active Optical Cable) is an integrated cable assembly. The optical transceivers are permanently attached to both ends of the fiber cable. It's a single, plug-and-play unit for short-reach connections (typically inside a rack).

An Optical Transceiver is a modular, pluggable device. It inserts into a switch or server port, and you must separately connect a fiber cable to it. It is flexible and used for various distances (from short to long reach)

What is an AOC Cable?

An Active Optical Cable (AOC) is a factory-terminated, fiber optic cable assembly with embedded optical transceivers at both ends. It provides a complete, plug-and-play optical link solution. Compared to a configuration using two discrete optical transceivers and a separate fiber cable, AOCs typically offer lower total cost, higher reliability, and easier deployment, making them a popular choice for many applications.

AOC Cable

What is an Optical Transceiver?

Optical transceiver modules, such as SFP+, QSFP28, QSFP56, QSFP-DD, etc., convert electrical signals to optical signals and are paired with separate fiber optic cables. Transceiver-based solutions remain dominant in enterprise networks, telecom systems, and long-distance optical connections.

Features of Optical Transceiver:

High flexibility: mix and match transceivers and cable types

Easy maintenance and component replacement

Support for short-reach, long-reach, and ultra-long-reach links

Interoperability across different equipment manufacturers

Optical Transceiver

From a Technical Point of View, What is the Difference between AOC and Optical Transceiver + Optical Fiber?

Like an optical transceiver, an AOC performs electro-optical conversion. However, their design philosophies, component choices, and cost structures differ fundamentally, primarily due to the deterministic nature of the AOC link.

For a pluggable optical transceiver, as a universal interface, it must be designed to operate reliably with various unknown opposite-end transceivers and fiber links under diverse environmental conditions. Consequently, it requires high-performance, thermally stable lasers in hermetic packages  and complex circuitry to meet stringent industry standards (MSA). Its manufacturing involves precision optical alignment to a universal connector interface, which is a highly automated but capital-intensive process.

For an AOC, the link is a fixed, point-to-point assembly with known and matched endpoints over a very short distance. This determinism allows for significant optimizations: it can employ lower-cost, non-hermetic chip-on-board (COB) optical engines, drastically simplified peripheral circuits, and a minimized mechanical housing. The optical coupling is optimized for this specific, short-reach link, allowing for higher coupling tolerances. Crucially, it eliminates two external fiber connectors and their associated alignment structures.

The Cost of AOC Active Optical Cable and Optical Transceiver is Different

While Active Optical Cables (AOCs) may offer an upfront cost advantage, they present notable operational and maintenance challenges when compared to pluggable transceiver solutions. As an integrated, non-serviceable assembly, an AOC cannot be repaired or partially replaced—if any single component fails, whether the transceiver, fiber, or connector, the entire cable must be removed and replaced. In densely wired environments such as data center racks, this often means disruptive re-cabling work, increasing both downtime and operational complexity. Moreover, AOCs lack the flexibility and interoperability required in multi-vendor networks. With pluggable transceivers, engineers can simply select compatible, vendor-coded modules for each end as equipment changes. By contrast, AOCs must be pre-programmed with specific vendor codes during manufacturing and carefully labeled (for example, “End A for Cisco, End B for Arista”) to avoid connection errors. This inherent rigidity not only complicates installation and maintenance but also limits scalability and makes future upgrades far less adaptable.

AOCs and optical transceivers are built on similar optical technologies but differ in design philosophy and application. AOCs integrate the transceivers and fiber into a single, factory-terminated assembly, reducing installation steps, minimizing interface losses, and enabling quick, plug-and-play deployment, which can be more cost-effective for short-reach, standardized connections in consistent environments such as data center racks. In contrast, optical transceivers offer greater flexibility, stronger interoperability, and better maintainability, as their modular design allows independent replacement and easier adaptation in multi-vendor, complex, or longer-distance networks. Understanding these differences helps organizations select the most efficient and cost-effective solution for their specific network architecture and performance needs.

FAQ of AOC and Optical Transceiver

1. What is the main difference between AOC and optical transceivers?

AOCs are fully integrated cable assemblies with fixed fiber, while optical transceivers are modular and work with separate fiber patch cords. AOCs offer simpler, plug-and-play deployment, whereas optical transceivers provide greater flexibility, compatibility, and support for longer transmission distances.

2. Which is more cost-effective?

For short-distance links (typically 1–100 m), AOC solutions are usually more economical due to simplified integration and fewer components. For longer distances or multi-vendor environments, optical transceivers are often more cost-effective thanks to their flexibility and reusability.

3. Can AOC and optical transceivers deliver the same performance?

Yes. Both are based on similar optical technologies and can support high data rates such as 10G, 25G, 40G, 100G, 200G, and 400G. The key difference lies in structure and deployment, not data rate capability.

4. What are optical transceivers typically used for?

Optical transceivers are widely used in:

a. Data center aggregation and core networks

b. Telecom and ISP infrastructure

c. Campus backbone networks

d. Long-distance optical links (up to 80 km or more, depending on module type)

5. How do I choose between AOC and optical transceivers?

Choose AOC if you need a cost-effective, plug-and-play solution for short-distance connections in a stable environment.

Choose optical transceivers if you require long-distance transmission, multi-vendor compatibility, easier maintenance, and greater network design flexibility.

We know that both 100G active optical cables (AOC) and 100G direct attach cables (DAC) are used to transmit data. However, there are some di

We know that both 100G active optical cables (AOC) and 100G direct attach cables (DAC) are used to transmit data. However, there are some differences between 100G active optical cables and 100G direct attach cables. Next, we will introduce the difference between these two types of cables in detail.

1. What is 100G active optical cable?

100G active optical cable refers to the communication cable that needs to use external energy to convert electrical signals into optical signals or convert optical signals into electrical signals during the communication process. The optical transceivers at both ends of the optical cable provide photoelectric conversion and optical transmission functions, and the transmission rate reaches 100Gb/s.

2. What is 100G direct attach cable?

100G direct attach cable adopts silver-plated conductor and foamed insulated core wire, which has excellent low attenuation performance and low delay performance, so that the signal transmission is accurate and precise, and the transmission speed can be improved. It is a short-distance connection solution that replaces the optical transceiver. Moreover, the price of this cable is much cheaper than that of the same type of optical transceivers, and it is widely welcomed in short-distance connection applications.

3. Structure of 100G AOC active optical cable

Simply put, the active optical cable is composed of two optical transceivers and an optical cable jumper. The optical fiber transceiver at both ends consists of OM3 or OM4 multimode fibers of different lengths.

4. Structure of 100G direct attach cable

Direct attach cable is abbreviated as DAC. Its both ends are connected to switches or servers to realize short-distance transmission. High-speed cables can be divided into passive direct attach cables and active direct attach cables. Active direct attach cables has only one more driving chip than passive high speed cables. The "optical transceivers" on direct attach cables are not optical transceivers in the true sense. They have no components and can only transmit electrical signals. Therefore, direct attach cables are cheaper than other ordinary optical devices. Even if the same port is used as interfaces of optical transceivers, direct attach cables can also effectively save costs and reduce power consumption in short-distance applications. This is the reason why people choose direct attach cables.

5. Classification of 100G AOC active optic cable

100G AOC active optical cable has two types: 100G QSFP28 active optical cable and 100G QSFP28 to 4X 25G SFP28 active optical cable. The former has an optical transceiver receiver at both ends to realize one-to-one transmission, and the latter has a 100G QSFP28 interface at one end, and four 25GSFP28 ports at the other end, which can provide customers with 100G data transmission.

6. Classification of 100G direct attach cables

There are two types of 100G direct attach cables: 100G QSFP28 DAC and 100G QSFP28 to 25G SFP28 DAC. The former has an optical transceiver receiver at both ends to realizes one-to-one transmission, and the latter has a 100G QSFP28 at one end of interface and four 25GSFP28 interfaces at the other end, which can provide customers with 100G data transmission.

It should be noted here that although the classification of the two is much the same, the optical transceiver of the active optical cable has a built-in laser, while there is no laser inside the direct attach cable.
