Timbercon asserts QSFP+ Passive Copper modules offer

Substituting the electrical loopback for a full featured transceiver provides a more cost-effective, low-cost alternative, Timbercon asserts.The electrical loopback is packaged in a standard MSA housing compatible with all QSFP+ Passive Copper ports.or transimpedance amplifier chips, it provides a more economical way to test QSFP+ Passive Copper during amp;D validation, production testing, and full system testing, Timbercon believes.In addition to the electrical loopback function, the QSFP/QSFP+ provides an MSA standard 2-wire serial communication interface to digital diagnostics and preloaded EEPROM two-page memory map.The addition of the QSFP+ Passive Copper to our XFP, SFP and SFP+ electrical loopbacks has strengthened our commitment to economical board testing as well as full system testing using our Armadillo optical loopbacks.Transmit data from the host is electrically routed (internal to the loopback module) to receive data outputs and back to the host. Because the electrical loopback module does not contain laser diodes, photodiodes, a laser driver
