Generic Compatible QSFP-100G-LB 100G QSFP28 0dB 0W Passive Loopback Testing Module

Generic Compatible QSFP-100G-LB 100G QSFP28 0dB 0W Passive Loopback Testing Module

direcXource's QSFP-100G-LB loopback is a 100Gbps Quad Small Form-factor Pluggable QSFP28 loopback module for cost effective port testing. QSFP28 LB routes 100Gb/s data stream from transmitting side back to receiving side of the same host port by looping back the electrical signal. The QSFP28 loopback module implements 4 independent 25 Gbps transmit and receive signal channels in each differential trace for an aggregate 100 Gbps data rate. This loopback is fully compliant with QSFP28 Multi-Source Agreement (MSA) and IEEE 802.3bj 100GBASE-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 QSFP28 equipped network routers/switches, blade servers and adapter cards. Protocol-transparent design ensures widely compatibility with various signal standards, including 100 Gigabit Ethernet (100GbE), 4x EDR InfiniBand and proprietary interconnection. MSA memory map are accessible via 2-wire Interface (TWI/I2C). An optional bicolor LED light is available to indicate the power status.
