The UC INSTRUMENTS CA9803 4 x 28 Gb/s Bit Error-Rate Tester is a high performance, easy to use, all-in-one, costeffective, 4 x 28 Gb/s Bit Error Rate Tester (BERT) for current 100 G TOSA/ROSA components R&D and manufacturing environments as well as field installations. The CA9803 incorporates an internal reference clock, a pattern generator, clock recovery circuits, and a BER analyzer, in one compact module that provides both electrical and optical interfaces at data rates up to 28 Gb/s. The CA9803 is offered with an RS-232 or USB interface. The PPRBS outputs optical NRZ waveform with bit rate within 25 to 28 Gbps, with settable data pattern of 2^7-1, 2^9-1, 2^11-1, 2^15-1, 2^23-1, 2^31-1, and a fixed 64 bit userdefined pattern. The BERT system is controlled by external computer via a USB port, with full software support, drivers and programming guide for automation.
