Timbercon releases SFP+ electrical loopback for port testing

JUNE 4, 2009 -- In addition to the electrical loopback function, the EL-11-07001 provides an MSA-standard two-wire serial communication interface to digital diagnostics, preloaded EEPROM memory map, and enhanced housing for improved heat dissipation.

JUNE 4, 2009 -- Timbercon Inc. (search Lightwave for Timbercon) has finalized its SFP+ electrical loopback after three months of prototype testing. The company has completed all design and engineering phases and has begun manufacturing production quantities for sale to all SFP+ users and designers.

The Timbercon EL-11-07001 SFP+ electrical loopback is used for testing SFP+ transceiver ports in host/system boards. Substituting for a full-featured SFP+ transceiver with an optical Armadillo Loopback delivers a cost-effective method for port testing, says Timbercon. In addition to the electrical loopback function, the EL-11-07001 provides an MSA-standard two-wire serial communication interface to digital diagnostics, a preloaded EEPROM memory map (standard and customized), and an enhanced housing for improved heat dissipation.

The device contains two LED indicators that display its operating status. A green LED illuminates when the loopback is seated and blinks when the temperature is beyond the allowable range. A red LED illuminates for a power-down status and blinks when the loopback shuts down due to extreme temperature.

"The SFP+ electrical loopback adds another weapon to the test engineer's arsenal in both manufacturing and development environments. The addition of the SFP+ to our XFP, SFP, and HSSDC2 electrical loopbacks has continued our commitment to economical board testing as well as full system testing with our Armadillo optical loopbacks," says John Lee, vice president of Timbercon.

In addition to releasing the EL-11-07001, Timbercon is also beginning commercialization of an SFP+ host test board, developed to provide a testing and programming platform for both the SFP+ and SFP electrical loopbacks. The board will comply with the SFP+ MSA standards and will come complete with operation software and user manual.
