Questions & Answers

Ask a Question

What are the advantages and applications of 100G CWDM4?

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.

How does 100G CWDM4 work?

At the transmitting end, 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 onto a single fiber to transmit at 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 a pair of 100G QSFP28 CWDM4 optical modules, do I need to turn on the forward error correction (FEC) function?

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