100G CWDM4 QSFP28 Optical Transceiver Module
Brand: Multi-Vendor (Commonly used in Cisco, Huawei, Juniper, Arista compatible form factors) · SKU: QSFP-100G-CWDM4 · MPN: QSFP-100G-CWDM4 · Category: Networking
The QSFP-100G-CWDM4 is a Quad Small Form-Factor Pluggable 28 (QSFP28) transceiver module designed for 100 Gigabit Ethernet links over Single-Mode Fiber (SMF). It utilizes CWDM technology, multiplexing four optical channels with center wavelengths at 1271 nm, 1291 nm, 1311 nm, and 1331 nm (or similar grids like 1270, 1290, 1310, 1330 nm depending on standard) onto a single fiber. It supports an aggregated data rate of 103.125 Gbps (4 x 25.78125 Gbps) and typically reaches up to 2 km. The module features a duplex LC connector, supports Digital Diagnostic Monitoring (DDM/DOM), and often requires Host Forward Error Correction (FEC). It operates on a single +3.3V power supply with maximum power dissipation generally around 3.5W. The electrical interface is CAUI-4 compliant, and it is compliant with the 100G CWDM4 MSA.
