25G SFP28 Active Electrical Loopback Module
The GSS-MPO250-LP SFP28 active electrical loopback module is designed for testing 25G SFP28 transceiver ports at the board level. It provides a cost-effective and low-loss method for SFP28 port testing by substituting a full-featured SFP28 transceiver. The module is packaged in a standard MSA housing compatible with all SFP28 ports, routing transmit data from the host internally to the receive data outputs and back to the host. It is ideal for R&D validation, production testing, and field testing.

Product Model: QSFP28 host board V1.30 PCB Marking: E206460 PCB Number: AL-85MA-0
QSFP28 Host Board V1.30 is a high-speed host-side evaluation/test PCB for 100G QSFP28 optical transceivers. The board routes the QSFP28 electrical interface to an arc array of gold SMA coaxial connectors around the top edge and to a QSFP28 cage/connector at the bottom center, enabling signal-integrity, compliance and interoperability testing of QSFP28 modules on the host side. PCB markings include E206460, AL-85MA-0 and the revision label "QSFP28 host board V1.30".
