LTA1303-PC+ QSFP+ Optical Transceiver

CWDM 4X10.3125Gb/s 2kM

The LTA1303 QSFP+ Optical transceiver is intended for the service with single mode fiber in 40Gb/s high speed data communications and computing applications. It meets the requirements of QSFP+ MSA, IEEE802.3ba 40GBASE-LR4, 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 40Gb/s by multiplexing of 4 CWDM optical lanes, each lane capable of transmitting 10.3125Gb/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 2011/65/EU for RoHS compliance.
