Cisco QSFP-100G-CWDM4-S Compatible 100G-CWDM4 QSFP28 1310nm 2km DOM Duplex LC Transceiver Module for SMF

High bandwidth: It supports a 100Gbps data transmission rate to meet the demand for high-speed data communication. Saving fiber resources: By using CWDM technology, four wavelengths are multiplexed onto a single mode fiber, thus saving fiber resources. Suitable for short-distance transmission: Suitable for short-distance data center interconnection, server-to-server connection, and other application scenarios.

At the transmitter side, the QSFP28 CWDM4 optical module first converts four electrical signals with a transmission rate of 25Gbps into four CWDM optical signals and then multiplexes them on a single fiber to transmit a rate of 100Gbps. At the receiving end, the QSFP28 CWDM optical module first breaks down the optical input signals into four channels of CWDM optical signals and then converts them into four electrical output signals.

When using 100G QSFP28 CWDM4 optical modules, both ends need to turn on or off the FEC function at the same time (turning on the FEC function is to reduce the BER).
