HANOVER, Md., March 15, 2014 — Pharad has introduced the MBC-DF-UC-U dither-free modulator bias controller for OEM applications including stable control of lithium niobate and gallium arsenide modulators.
The 2.5 × 2-in. device features continuous tuning of the modulator bias voltage via USB computer control. It operates in conjunction with onboard, in-line optical power monitors, eliminating the need for external optical couplers or photodetectors. The board’s dither-free control avoids pilot tones found in many bias controllers, making it suitable for high-performance analog fiber optic links.
