QSFP28 100G 2km transceiver
The QSFP28 100GBASE-LR 2km module is designed for data transmission using two single-mode (SM) fibers. It transmits data at speeds of up to 100 Gbps, over distances of up to 2km. It works with 4 CWDM 25Gb/s DML lasers and has 2xLC/UPC duplex optical connector type. Compliant with the MSA standard.
We program the modules before shipment to work with any manufacturer of switch, converter, server card. If you did not find the manufacturer's name in the list, select "Other" option at the end of the list.
Universal module, working reliably at distances up to 2km, but also on very short, 1-meter lines. You don't have to worry about the insertion laser being damaged, thanks to a properly designed receiving diode that is resistant even to long-distance lasers.
