Munich Instruments offers C-BERT for 4x25G optical transceiver, component testing

Test and measurement systems developer Munich Instruments is showing off the C-BERT MI-PE2810–4 quad 25 to 29 Gbps Bit-Error-Ratio Tester (BERT) series at ECOC 2014 in Cannes, France. The family of three instruments features a built in reference clock, PRBS generator, error counter, and clock data recovery (CDR) unit, as well as the ability to test all four channels simultaneously.

According to sources at the show, the instrument can be used in a variety of applications, but is likely to find particular favor in production environments because of its low cost and small size. The C-BERT has an internal, highly stable, low-jitter clock generator that Munich Instruments asserts renders an external clock unnecessary. The pattern generator and the error detector are integrated into a single 19-inch chassis.

The three variants address different applications. These include one option for 100-Gbps small form factor transceivers testing, including CFP2, CFP4, and QSFP28; another for 4x25G TOSA evaluation; and a third for ROSA testing.

The three variants are available now and have already been delivered to customers, the company sources said.
