Cisco DP04QSDD-HE0 400GB DWDM SMF 120km Duplex LC/UPC QSFP-DD Transceiver

The Cisco DP04QSDD-HE0 is a 400 Gbps QSFP-DD transceiver module manufactured by Cisco. It supports single-mode fiber and uses duplex LC/UPC connectors for transmission over Dense Wavelength Division Multiplexing (DWDM) in the wavelength range of 1528.77 to 1567.13 nm.

This pluggable optical transceiver provides up to 120 km reach using standard SMF cabling, designed for high-capacity long-haul applications within telecom or data center networks that support DWDM infrastructure. The unit integrates with compatible QSFP-DD ports across select routing and switching platforms from Cisco or other vendors where supported, enabling dense port configurations through its compact form factor.
