12F MPO APC Female Loopback Single Mode with customizable attenuation

Product Overview

The 12-Fiber MPO/APC Female Loopback Module is engineered for high-performance optical network testing. It is specifically designed to simulate a complete optical circuit, enabling effective diagnostics and validation of single-mode fiber networks. With an angled physical contact (APC) polish and customizable attenuation, this loopback is ideal for testing applications in Telecom, Data Center, FTTH, and OTN infrastructures. It supports various transceiver interfaces such as QSFP, QSFP28, and OSFP, used in high-speed links up to 400G.
