General Photonics TCA-1000 SmartLight

"It's no secret that PMD can have undesirable performance impacts on fiber optic data transmission links exceeding 10 Gb/s," said Steve Yao, President of General Photonics.

General Photonics, a market leader in optical networking instruments, modules and components, today announced the general availability of its TCA-1000 SmartLight™, a tunable ASE source with 50 GHz channel spacing on the ITU grid. With a FWHM bandwidth of 0.3 nm, this fully polarized light source can be used to emulate a 40 Gb/s signal for PMD effect tests; in-service link PMD measurement; PMD compensator evaluation; WDM channel testing; 40G system testing; and 40G component testing.

The TCA-1000 features a built-in polarization rotator allowing its use in conjunction with General Photonics’ PMDPro™ PMD-1000 polarization optimized PMD source to monitor or measure the PMD of an in-service WDM channel. It can also be used to evaluate the performance of PMD compensators with DOP feedback. It is an ideal light source for measuring spectrum-averaged values of parameters such as the insertion loss (IL), polarization dependent loss (PDL), and return loss (RL) of a fiber component on a 40 Gb/s signal for each WDM channel. The TCA-1000's polarization rotator rotates the output polarization by 45 degrees with a speed of 0.2 ms.

"It's no secret that PMD can have undesirable performance impacts on fiber optic data transmission links exceeding 10 Gb/s," said Steve Yao, President of General Photonics. "One of the major applications of the TCA-1000 is to aid our PMDPro to accurately measure the PMD values of in-service optical light paths with 50GHz spacing. Measurement on in-service links delivers advanced performance insight into service provider networks."

The TCA-1000 wavelength is C band. The wavelength channel can be tuned either via the front panel keypad or via the communication ports on the rear panel. Tuning speed is less than 10 seconds. Standard communication interfaces include RS-232, USB, Ethernet, and GPIB. Maximum power output is 16 dBm and the power attenuation range is 20dB. The output power level can be conveniently controlled via an internal VOA. Short term power stability is 0.004 dB over 1 minute and long term power stability is 0.05 dB for more than 8 hours.

Pricing and Availability
The TCA-1000 SmartLight is available immediately. Interested parties may contact General Photonics direct or a General Photonics channel partner near them for additional availability and pricing details.
