LMQ3926 QSFP-DD FR4 Optical Transceiver 4x100G CWDM4 2km

The LMQ3926-PC+ is a QSFP-DD Optical transceiver for 4x100Gb/s optical links. It meets the requirements of QSFP-DD MSA, operates from a 3.3V DC power supply and is offered in the commercial temperature range. The module has an aggregate link bandwidth in excess of 4x100Gb/s by multiplexing of 4 CWDM optical lanes, each lane capable of transmitting PAM4 53.125GBd over 2km on SMF optical fiber. It is fabricated with a rugged die cast metal housing and cage assembly. The device is Class I laser safety compliant and meets the EU Directive 2002/95/EC for RoHS compliance.
