Generic Compatible QSFPDD-400G-LB 400G QSFP-DD 0dB 1.5-15W Passive Loopback Testing Module

direcXource's QSFPDD-400G-LB loopback is a 400Gbps Quad Small Form-factor Pluggable - Double Density QSFP-DD loopback module for cost effective port testing. QSFP-DD LB routes 400Gb/s data stream from transmitting side back to receiving side of the same host port by looping back the electrical signal. The QSFP-DD loopback module implements 8 independent 50 Gbps PAM4 transmit and receive signal channels in each differential trace for an aggregate 400 Gbps data rate. It also supports 8 channels 25 Gbps NRZ signals for 200 Gbps testing. This loopback is fully compliant with QSFP-DD Multi-Source Agreement (MSA) and IEEE 802.3cd 400GBASE-CR8 standard. The electrical interface is MSA compliant 76-pin edge type connector and the internal loopback by AC coupling internally. Our loopback is designed for R&D evaluation, production testing of QSFP-DD equipped network routers/switches, blade servers and adapter cards. Protocol-transparent design ensures widely compatibility with various signal standards, including 400 Gigabit Ethernet (400GbE), 8x HDR InfiniBand and proprietary interconnection. Real time temperature, voltage monitoring and CMIS memory map are accessible via 2-wire Interface (TWI/I2C). Different power dissipation class up to 16 W is programmable and an optional bicolor LED light is available to indicate the power status.
