The Cisco QDD-2X100-CWDM4-S is a QSFP-DD form factor transceiver supporting 200 Gbps data transmission over dual 100G lanes. Built by Cisco, it operates on single-mode fiber and connects via CS connectors across CWDM wavelengths from 1270 nm to 1330 nm.
This transceiver conforms to the QSFP-DD Multi-Source Agreement for high-density networking applications. It supports up to two kilometers of reach on SMF using coarse wavelength division multiplexing (CWDM). The module contains two optical transmit and receive paths enabling duplex communication at aggregate speeds of 200 Gbps.
