Generic Compatible QSFP-40G-LB 40G QSFP+ 0dB 0W Passive Loopback Testing Module

Generic Compatible QSFP-40G-LB 40G QSFP+ 0dB 0W Passive Loopback Testing Module

direcXource's QSFP-40G-LB loopback is a 40Gbps Quad Small Form-factor Pluggable QSFP+ loopback module for cost effective port testing. QSFP+ LB routes 40Gb/s data stream from transmitting side back to receiving side of the same host port by looping back the electrical signal. The QSFP+ loopback module implements 4 independent 10 Gbps transmit and receive signal channels in each differential trace for an aggregate 40 Gbps data rate. This loopback is fully compliant with QSFP+ Multi-Source Agreement (MSA) and IEEE 802.3ba 40GBASE-CR4 standard. The electrical interface is MSA compliant 38-pin edge type connector and the internal loopback by AC coupling internally. Our loopback is designed for R&D evaluation, production testing of QSFP+ equipped network routers/switches, blade servers and adapter cards. Protocol-transparent design ensures widely compatibility with various signal standards, including 40 Gigabit Ethernet (40GbE), 4x QDR InfiniBand and proprietary interconnection. MSA memory map are accessible via 2-wire Interface (TWI/I2C).
