Are the transmit and receive functions the same for the 1310 optical module

A 1310nm single mode optical transceiver works by converting electrical data signals into optical signals at the 1310nm wavelength, transmitting them through single-mode fiber, and then converting them back into electrical signals at the receiving end. These devices, part number PW85ST, are designed to simultaneously transm t and re-ceive over a single optical fiber at frequencies from DC to 200MHz. Most systems operate by transmitting in one direction on one fiber and in the reverse direction on another fiber for full. With the optical CATV transmitter, the optical 4-way upstream receiver, the optical de-/multiplexer and the micro fibre nodes, Axing offers a complete fibre optic transmission link for downstream and upstream. The fibre optic technology uses 1550 nm in the downstream and 1310 nm in the upstream. BiDi SFPs connect to a fiber cable using only one simplex port, whereas standard transceivers have duplex fiber ports.

Fiber Optic Temperature Sensor Design Principles

In this chapter, a temperature sensor is demonstrated based on four different techniques; intensity modulated fiber optic displacement sensor (FODS), lifetime measurements, microfiber loop resonator (MLR) and stimulated brillouin scattering. Fiber Bragg gratings are very efficient at temperature sensing and are easy to implement; however, they always need additional techniques to discriminate the Bragg shifts by temperature and by strain/compression and they also require expensive phase-masks. Fiber-Bragg-Gratings (FBGs) are used for spot sensing, whereas Rayleigh, Brillouin and Raman scattering are used for distributed sensing in long fibers. This is done by adding a periodic variation to the refractive index of the fiber core. ▪ One of the main advantages of this technology is its iiiiintrinsic.
