What are the key performance indicators of a spatial light modulator
A spatial light modulator (SLM) addressed with Computer Generated Holograms (CGH's) can create structured light fields when an incident laser beam is diffracted by a phase CGH.

The light receiving module was damaged by the OTDR
A patch cord, launch fiber, or fiber segment has the wrong core size, backscatter coefficient, or mode. OTDR (Optical Time Domain Reflectometer) testing is a vital technique for characterizing and troubleshooting optical fiber networks. If the receiving power is low (RxPower Low), the signal received is too weak, possibly due to excessive transmission distance or fiber damage.

100G optical module with four channels for different light reception
This product is a parallel 100G QSFP28 optical module with 4 independent transmit and receive channels each capable of 25Gb/s operation. These standards often cause confusion when selecting the right module for your needs. The QSFP28 LR4 is a hot-pluggable, four-channel, and full-duplex optical transceiver module designed for long-distance transmission up to 10 km in the 100G Ethernet network with a working bandwidth of 1295nm to 1310nm. The 100G QSFP28 optical transceiver module is a high-speed optical communication module commonly used in application scenarios such as data centers, cloud computing, and high-performance computing. The commonly used module types include SR4, LR4, ER4, PSM4, ZR4, SR BIDI, and SWDM4.
