Cisco QDD-400G-XDR4-S Compatible 400GBASE-XDR4 QSFP-DD PAM4 1310nm 2km SMF MTP/MPO-12 DOM Optical Transceiver Module
Cisco QDD-400G-XDR4-S compatible optical transceiver is a parallel 400Gbps Quad Small Form-factor Pluggable - Double Density QSFP-DD module for use in 400GBASE Ethernet. QSFP-DD XDR4 provides 400Gb/s throughput up to 2km over single-mode fiber (SMF) with host FEC using 1310nm wavelength. This transceiver is fully compliant with QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3bs 400GBASE-XDR4 and 400GAUI-8 standard. Its electrical interface is MSA compliant 76-pin edge type connector and the optical interface is MTP/MPO-12 APC connector. The full-duplex QSFP-DD transceiver implements 4 independent 106.26 Gbps PAM4 transmit and receive signal channels in each fiber for an aggregate 400 Gbps data rate. Built-in Digital Diagnostic Monitoring (DDM) support is present for real-time performance monitoring via 2-wire Interface (TWI/I2C). Our modules are factory pre-programmed for compatibility, perform identically to original Cisco QDD-400G-XDR4-S transceivers.
