AWG: 40/48 Waves Multiplexing/Demultiplexing Card

Part of the DWDM/CWDM/OTN transmission

AWG split-wave card is mainly used in the DWDM system to complete 40/48 optical wavelength multiplexing and demultiplexing functions in the C-band range, which can multiplex different wavelengths of light into one. Multiple optical channels multiplexed on the same fiber are separated by wavelength on the fiber. It is based on waveguide grating technology on silicon substrates design for precise channel coupling, low insertion loss, high channel isolation and high stability for 40/48-wave high-capacity DWDM systems.

OTDR Card

During OTDR testing, pulses generated by the pulse generator drive the laser diode (LD) to emit light pulses. These pulses are directed into the fiber under test through a directional coupler. Scattering occurs within the fiber due to impurities and bubbles, with some of this backward scattering (BACK SCATTERINGLIGHT) combining with Fresnel reflections from irregular fiber end surfaces. The resulting light is reflected back to the coupler and captured by photodiodes, where it is converted into electrical waves. Given the extremely weak nature of this reflected light, it undergoes repeated transmission, collection, averaging, and amplification before being processed by the network management platform. This system features high dynamic range and superior resolution
