Cisco QDD-400G-SR8-S Compatible 400GBASE-SR8 QSFP-DD PAM4 850nm 100m MMF MTP/MPO-16 DOM Optical Transceiver Module

Cisco QDD-400G-SR8-S Compatible 400GBASE-SR8 QSFP-DD PAM4 850nm 100m MMF MTP/MPO-16 DOM Optical Transceiver Module

Cisco QDD-400G-SR8-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 SR8 provides 400Gb/s throughput up to 100 meters over OM4 or 70 meters over OM3 multi-mode fiber (MMF) with host FEC using 850nm wavelength. This transceiver is fully compliant with QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3cm 400GBASE-SR8 and IEEE 802.3bs 400GAUI-8 standard. Its electrical interface is MSA compliant 76-pin edge type connector and the optical interface is MTP/MPO-16 APC connector. The full-duplex QSFP-DD transceiver implements 8 independent 53.125 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-SR8-S transceivers.
