LTA1304-PN QSFP28 Optical Transceiver
CWDM 4X25Gb/s 2km

The LTA1304 QSFP28 Optical transceiver is intended for the service with single mode fiber in 100G optical interconnect optimized for data -center applications. It meets the requirements of QSFP28 MSA, 100G-CLR4,CWDM4 MSA, operates from a 3.3V DC power supply and is offered in the narrow temperature range. The module has an aggregate link bandwidth in excess of 100Gb/s by multiplexing of 4 CWDM optical lanes, each lane capable of transmitting 25.78125Gb/s 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.
