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.

Optical Variable Attenuator

An optical attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.

Attenuators are commonly used in fiber optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. Sharp bends stress optic fibers and can cause losses. If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired level of attenuation is achieved.However, such arrangements are unreliable, since the stressed fiber tends to break over time.

GT3303 handheld optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, there, therefore GT3303 can be used in the digital system of communication devices like PDH, SDH and also in the system of adopting analog modulation (CATV).
