Brellet Telecom’s POL (Passive Optical LAN) Solutions
With the rapid development of cloud computing, big data and 4K video, the traffic model has evolved from traditional horizontal traffic to a cloud + terminal vertical traffic model. At the same time, enterprise services have increasingly higher requirements for bandwidth and delay. Traditional enterprise networks can no longer meet these new changes and new needs of the enterprise. In response to customer needs and challenges, Brellet Telecom provides an all-optical network POL solution to reduce latency and smoothly evolve bandwidth to 10G to meet the evolutionary needs of cloud computing services. Brellet Telecom can provide all-optical network products for the entire industry chain, covering PON products, optical fiber and cable, ODN, etc. At the same time, based on years of network construction experience, we can customize network solutions for different scenarios and tailor all-optical network POL solutions for you.
PON Basic Concepts
PON (Passive Optical Network) is a passive optical network with a point-to-multipoint (P2MP) structure.
OLT (Optical Line Terminal) is convergence equipment that is placed at the central office to terminate the PON protocol.
ONU (Optical Network Unit) is a terminal that is located at the customer end and provides users with various interfaces.
ODN (Optical Distribution Network) is composed of optical fiber and one or more passive optical splitters (POS), which connect OLT and ONU.
POL Network Architecture
POL (Passive Optical LAN): Passive optical local area network, a new type of local area network networking method based on PON technology, optimizes the basic wiring and network structure of the local area network and the network structure is flatter and simpler. It inherits the advantages of PON network such as large bandwidth, high reliability, flatness, easy deployment and easy management.
POL network uniformly carries services such as broadband, voice, video, WiFi, CATV and office.
POL solution is widely used in scenarios such as hotels, campuses, corporate parks, corporate office buildings, electricity and transportation.
POL Features
Due to the different network scales and different types of users, POL solution has made corresponding optimizations to ensure a better adaptation to the business needs of the enterprise. Through the POL solution, enterprises can combine different systems such as data, voice, video and wireless access into a single fiber optic network, which has advantages that other technologies cannot match.
All-optical network transmission, broadband, voice, video, WiFi, CATV and other multi-service integration and a single optical fiber transmits multiple services.
Adopt POL passive all-optical network networking, no electromagnetic interference, long service life, almost no maintenance and low cost.
Adopting POL passive all-optical network networking, the later expansion is flexible and it can be smoothly upgraded to a more advanced network system without rewiring.
POL and Traditional LAN
POL and Traditional LAN network structure comparison:
In the POL network, the aggregation switch in the traditional LAN is replaced by the OLT; the copper cable is replaced by the optical fiber; the access switch is replaced by the passive optical splitter.
ONU provides Layer 2/Layer 3 functions to access users’ data, voice and video services via wired or wireless access.
ODN Deployment
ODN (Optical Distribution Network) The optical distribution network is an FTTx optical cable network based on PON equipment and its function is to provide an optical transmission channel between the OLT and the ONU. Based on application scenarios, it can be roughly divided into park type and building type.
