Field Applications OTDR And ORL Measurements

GTFIBER.com (Part of EXFIBER Group) was created in response to growing industry demand from fiber optic installers and telecom service providers from around the globe. The fiber optic industry has clearly stated a need for a comprehensive fiber optic product outlet. With this objective in mind, each sector of the data fiber industry will now be able to find everything they need under one roof – whether it be for laboratory, manufacturing, LAN data networks, telecom/cable/internet service providers, FTTH, or even aerospace & military. Our stated goal is to be the standard by which other fiber optic suppliers are measured.

Today’s high-speed systems are comprised of many highly sensitive components, and great care must be taken to ensure that proper operating conditions are created and maintained. Failure to control optical return loss (ORL) in systems will cause high bit error rates resulting from multipath interference, degraded optical signal-to-noise ratio (OSNR) and transmitter instability. This application note will focus on a detailed description of this phenomenon and on the importance of accurately measuring ORL and identifying its main components.

What is ORL?

When light is injected into a fiber-optic component, such as a connector, a multiplexer or the fiber itself, some of the energy is transmitted, some is absorbed and some is reflected. The total light that comes back (i.e., reflected) is what we call ORL.

ORL is caused by two fundamental effects:

Rayleigh scattering effect; specifically, the part that goes back to the source point, known as backscattering

Fresnel reflections

Rayleigh scattering is intrinsic to the fiber itself. It consists of the light interacting with the density fluctuations of the fiber. It can be caused by a variation in the material density and composition that give rise to a variation of the fiber’s refractive index. This causes part of the wave to escape from the waveguide. The phenomenon is called scattering when the size of the defect is less than one tenth of the wavelength’s incident light, while backscattering refers to the part that is captured in the fiber and that propagates in the backward direction.

Because it is intrinsic to the fiber, backscattering cannot be eliminated. The intensity will depend on many factors such as the incident light wavelength and the refractive index and length of the fiber, etc. Over long distances, ORL caused by Rayleigh backscattering can be as high as 32 dB. Therefore, it is very important to consider this phenomenon during network design.

As another important component of ORL, Fresnel reflections are also related to a variation in the index of refraction. This phenomenon will typically occur at discrete interfaces (connectors, adapters, etc.) as a result of air gaps, misalignment, and mismatched refractive indices. Because it results from discrete interfaces, Fresnel reflections have to be optimized during fiber and system component installation in order to ensure proper conditions.

There are many different ways of testing ORL. The method chosen will depend greatly on the scope of the test. For example, the way a field technician tests when commissioning a new span may vary greatly from the way a central office technician tests during system turn-up or troubleshooting. Here are four methods supported by the IEC 61300-3-6 standard:

Optical Continuous-Wave Reflectometer (OCWR): OCWRs directly measure the incident power and reflected power. This method is very accurate and provides the nearest value to the theoretical definition of ORL. However, it cannot spatially resolve many different reflections on the line. Back reflection meters are based on this approach.

Optical Time-Domain Reflectometer (OTDR): OTDRs measure return loss from reflection points on the optical line with nanometer spatial resolution. Today, most OTDRs also allow an operator to extract an ORL measurement from the OTDR trace.

Optical Low-Coherence Reflectometer (OLCR): OLCRs measure reflection profiles of singlemode optical devices with micrometer spatial resolution.

Optical Frequency-Domain Reflectometer (OFDR): OFDRs measure the return loss of single optical devices with a centimeter spatial resolution.

Fiber Cleaver And Fiber Optic Cables - GTFIBER

Simplex fiber is a single fiber available in single mode, multimode, or polarization maintaining.

Duplex fibers consist of two fibers, both single mode or multimode, and are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction.

There are two types of duplex fibers:

Half-duplex: Data may only be transmitted in one direction at a time.

Full-duplex: Data is transferred in two directions simultaneously.

This should help explain the difference between SPLX vs DPLX.

Arc fusion splicing is commonly used to permanently join optical fibers. An arc fusion splicer is expensive, however the cost per fusion splice is usually low, and technical splice performance is excellent.

A fiber cleaver is a separate tool required to cleave fibers with a precise flat end face. Get a good one, and maintain it properly. It will critically affect splice quality. If you have to economise, don’t do it on this item.

The fusion splicer’s fiber alignment may be by a simple V-groove arrangement, or by a more expensive active alignment arrangement, which produces lower losses, and is also less sensitive to dirt. This choice depends on your optical fiber splicing requirements, volume and budget. Active alignment splicers are a favorite for regular use.

A common cause of field splicing failure is dirt adhering to the splicer v-groove, or dirt left on a fiber. V-groove dirt causes repetitive splice failure, and fiber dirt causes random splice failure. In both cases, cleaning procedures may need to be enforced or reviewed. In general, auto alignment machines are much more dirt tolerant than fixed v groove machines, which makes them preferred for field use.

The arc fusion splicer electrodes provide heat to melt the glass ends together. Correct electrode maintenance is critical. In particular, don’t make extensive use of the arc to blow dirt off the glass ends during fibre splicing, or the electrodes quickly become contaminated by the dirt particles.

A heater is used to apply a heat shrink splice protector. This shouldn’t be too aggressive, or residual glass stress left after cooling down can cause later splice unreliability. So use the manufacturer’s settings, or ask them before a change. The heater must not cause damage or bubbling to the fiber’s plastic coating, or later splice failure can occur. Some people use multiple heaters to increase throughput.

The splice protector is critical. It must cover the bare glass, plus a bit more. The bare glass must be straight (not bent) inside it, or later joint failure can occur. The splice protector must keep out moisture and atmosphere, both of which can weaken splice joints and cause later failure.

The fusion splicing technician needs procedures, training and familiarity with the particular apparatus, and both splicers and cleavers require programmed inspection & maintenance. If any of these are not happening, expect fibre splicing problems one day!

The most common causes of ongoing splicing failure are dirty or blunt splicer electrodes, and a worn or badly adjusted blade on the cleaver. So both splicers and cleavers require programmed inspection and maintenance by an expert technician.
