Description

This 100GBASE-XCWDM4 QSFP28 transceiver delivers 100G Ethernet over duplex single-mode fibre with an LC connector, using four 25G CWDM lanes in the 1271-1331 nm range. It supports link lengths up to 10 km, extending beyond the 2 km reach of the standard QSFP-100G-CWDM4 optic, while remaining interoperable with 100GBASE-CWDM4 optics at up to 2 km. Dual rate 100G/40G operation makes it suited to data centre interconnects, campus backbones and metro aggregation links.
