Generic Compatible QSFPDD-400G-LR4 400GBASE-LR4 QSFP-DD PAM4 1310nm 10km SMF LC DOM Optical Transceiver Module
direcXource's QSFPDD-400G-LR4 optical transceiver is a parallel 400Gbps Quad Small Form-factor Pluggable - Double Density QSFP-DD module for use in 400GBASE Ethernet. QSFP-DD LR4 provides 400Gb/s throughput up to 10km over single-mode fiber (SMF) with host FEC using 1271nm, 1291nm, 1311nm, 1331nm wavelength. This transceiver is fully compliant with QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3cu 400GBASE-LR4 and IEEE 802.3bs 400GAUI-8 standard. Its electrical interface is MSA compliant 76-pin edge type connector and the optical interface is Duplex LC connector. The full-duplex QSFP-DD transceiver implements 4 independent 106.26 Gbps PAM4 transmit and receive signal channels in each wavelength 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 generic MSA transceivers.
