Have you ever wondered how to evaluate the optical transceiver module interface when evaluating an FPGA?

One way to evaluate interfaces for optical transceiver modules is to insert a "loopback module" that loops back electrical signals into the cage of the optical transceiver module. This is a method of testing transmission and reception by returning the signal you sent and receiving it as is.

In fact, Intel Corporation is evaluating Intel Agilex 🄬7 using MultiLane's QSFP-DD loopback module.

Here are the three benefits of using MultiLane's QSFP-DD loopback module.

Please consider MultiLane's loopback module, which is relatively inexpensive and allows you to easily start testing.

MultiLane HCB is also available.

By using MultiLane's host evaluation board (HCB, Host Compliance Board), it is possible to extract electrical signals from the optical transceiver module port of network equipment and directly evaluate them.

The lineup covers a wide range from 1G to 400/800G, and supports multiple connectors. Please consider using it together with a loopback module.
