0dB Attenuation SFP/SFP+ Loopback Module

The FT-SFPPLUS-36 is a 0dB attenuation loopback module in an SFP/SFP+ package, built for testing and diagnostics of high-speed transceiver ports. It routes the transmit signal straight back to the receive side with no attenuation, letting technicians verify port operation, run burn-in cycles and isolate link faults without live traffic. The module supports data rates from 100Mbps up to 10.7Gbps and is hot-pluggable for quick insertion during maintenance. It includes a serial ID function plus automatic shutdown and self-protection circuitry. The design is fully compliant with the SFP+ MSA and the SFF-8431 standard, operates from minus 40 to 85 degrees Celsius, and runs on a 3.3V supply. As a Class 1 laser product it is safe for routine handling.
