6. Optical Project

- OTDR (optical time-domain reflect meter)

OTDRs are commonly used to characterize the loss and length of fibers as they go from initial manufacture, though to cabling, warehousing while wound on a drum, installation and then splicing. OTDR test results are often carefuly stored in case of later fiber failure or warranty claims. Fiber failures can be very expensive, both in terms of the direct cost of repair, and consequential loss of service. OTDRs are also commonly used for fault finding on installed systems. In this case, reference to the installation OTDR trace is very useful, to determine where changes have occurred. OTDRs are available with a variety of fiber types and wavelengths, to match common applications. In general, OTDR testing at longer wavelengths such as 1550 nm or 1625 nm, can be used to identify fiber attenuation caused by fiber problems, as opposed to the more common splice or connector losses.

- Splicer

Fiber Optic Cable Splicing

Two optical fiber splicing methods are available for permanent joining of two optical fibers. Both methods provide much lower insertion loss compared to fiber connectors.

1. Fiber optic cable fusion splicing – Insertion loss < 0.1dB
2. Fiber mechanical splicing – Insertion loss < 0.5dB

Fiber optic cable fusion splicing

Fiber optic cable fusion splicing provides the lowest-loss connection. Special equipment called fusion splicer is used to perform the fiber fusion splicing. The fusion splicer performs optical fiber fusion splicing in two steps.

1. Precisely align the two fibers
2. Generate a small electric arc to melt the fibers and weld them together
