High Bandwidth Electrical Generators

Alnair Labs offers high-speed optical and electrical instruments for evaluating optical networks such as picosecond Electrical Pulse Generators (EPG) and Bit Error Rate Testers (BERT). The EPG can provide sine or square signal type with a pulse width as narrow as 30ps or with pulse width tunability from 50 to 250ps. The BERT can provide data rates up to 28 Gbps with rise/fall times of 15 ps. Alnair also offers a Programmable Optical Delay Line with delays at either 1.25 or 2.5ns and a Modular Lightwave Controller with options of Half-wave plates, Quarter-wave plates, and Polarizers.
