Principle of Egyptian Temperature Measuring Optical Cable
The principle of operation is based on the temperature dependence of the bandgap of GaAs. The GaAs crystal fixed on the tip of the fibre will be transparent at a wavelength above 850 nm. The position of the band edge is temperature-dependent and is shifted about 0.4 nm/K. The light is directed via the optical fibre to the crystal, where it is absorbed and partially reflected into the fibre. A miniature spectrometer provides a spectrum with the position of the band edge, from which the temperature is calculated.

What is the minimum bit error rate for optical modules
Minimum Receiver Power (sometimes referred to as Receiver Minimum Input Power) is the lowest level of optical power at which the module is guaranteed to operate without exceeding a specified bit error rate (typically BER ≤ 10⁻¹²). To perform a bit error rate test, a pre-defined data stream is sent through a network link input, then the output of the link at the receiving end is analyzed to. Bit Error Rate (BER) is a critical performance metric in optical communications that measures the number of errors occurring in a transmitted data stream over a certain period. It is defined as the ratio of the number of bits received in error to the total number of bits transmitted.

Unloading the optical cable
While unloading it is important that the cable drum should not be dropped directly on the floor because it may damage the drum/cable so drum must always be ofload by crane or fork lifter for the upper layers and for ground layer ramp can also be use to unload drum from truck. The two main causes of cable squirting are dimensional instability of the reel and unequal tensions along the cable. Improper handling. This document provides the guidelines for handling and storage of Optical fiber cable drums. How can we avoid such kind of problems?
