Description

100G QSFP28 CWDM4 TransceiverWestbury's 100G QSFP28 CWDM41 module is IEEE 802. 3bm compliant with the form factor in line with the MSA for pluggability into all QSFP28 ports. We have SR4, CWDM4, LR4 and ER4 lite versions to choose from depending upon the reach and fibre type. The optical connector consists of either LC or MPO. For AoCs we supply a cable which is terminated at both ends (optical connector does not apply). These products are low power consumption and have been

3/100G DR1 compliant • Digital diagnostic functions (via I2C) • Compliant with RoHS

3bs and QSFP-DD MSA • Supports receiver signal strength indicator (RSSI) and transmitter output power monitoring (TOPM) Applications: • 400Gb Ethernet • Datacentre optical interconnect Specification summary • Data Rate: 400G • Supply voltage: 3
