Description

The QSFP-100G-CWDM4 is a 100GBASE-CWDM4 QSFP28 optical transceiver that reaches up to 2km over duplex single-mode fibre with an LC connector. It supports dual-rate 100G/40G operation, making it well suited to data centre and campus links that need to bridge 100G and 40G ports over standard duplex SMF.

The module uses the 1271/1291/1311/1331 nm CWDM grid and complies with the 100G CWDM4 MSA and the QSFP28 SFF-8636 standard. With a maximum power consumption of 3.5W, it suits dense switch deployments where power and thermal budgets matter.

Features

- Dual-rate operation at 100G and 40G
- Up to 2km reach over duplex single-mode fibre
- Compliant with the 100G CWDM4 MSA
- Low power consumption of 3.5W maximum
- Standard LC duplex connector for simple cabling
