SFP/QSFP Loopback System

Passive Loopback Test Adapter

The electrical passive loopbacks from 10Gtek intend to support Datacom, Infiniband, Fiber Channel applications, which provides a method for port operations testing in board and system. They are hot pluggable, constructed of metal cast for excellent EMI performance. 10Gtek provides extensive loopbacks on SFP+, SFP28, QSFP+, QSFP28 and QSFP-DD.

The 10Gtek passive electrical loopbacks are used for testing transceiver ports in board level test. The electrical loopback provides a cost effective low loss method for port testing. These loopbacks are packaged in a standard MSA housing compatible with all SFP+/SFP28/QSFP+/QSFP28 ports. Transmit data from the host is electrically routed (internal to the loopback module) to the receive data outputs and back to the host. Since the loopback module does not contain laser diodes, photodiodes, laser driver or trans impedance amplifier chips, etc., it provides an economical way to exercise the ports during R&D validation, production testing and field testing.

Loopback Clamps and Gang Holders

10Gtek 4-port loopback clamps & gang holders enable simultaneous testing of four ports at once. They possess all features of a single SFP+/QSFP+ loopback test adapter with an extra lock-protection to ensure safe locking during the measuring process. Models of 1x2, 1x3, 1x4, 2x2 of loopback clamps and 1x2, 2x2 port to port gang holders with cable are available to provide, on SFP+ or QSFP+.

10Gtek loopback clamps and gang holders, also named ganged loopbacks, are used for testing ports under board level tests. These loopbacks test port operation in equipment where transceivers are to be installed. The loopbacks are packaged in a standard MSA housing.
