Infinera-XLM-8-C3-DTC-UTStarcom

The Infinera-XLM-8-C3-DTC-UT is a switching line module designed for deployment in UTStarcom’s TN series packet optical transport platforms. This 8-channel optical transport module operates in the C-band (1530–1565 nm) and incorporates integrated Dispersion Compensation Technology for extended reach metro and core network applications. The XLM-8-C3 terminates and switches traffic via multiple Traffic Aggregation Modules and provides flexible signal routing across the host chassis switching fabric.
