All-in-one multi-channel optical module tester reduces evaluation time

100Gbit/s multi-channel optical modules can be inspected for manufacturing, using the All-in-One BERTWave MP2110A tester, released by Anritsu.

It is targeted at simultaneous bit error rate (BER) measurements and eye pattern analysis required for the evaluation of optical modules and devices used in optical communications systems, including 100GbE, InfiniBand EDR and 32G Fibre Channel.

To meet demand for increased data traffic volumes, within cost constraints, bit rates of optical modules used in data centres has increased from 10 to 25G. The BERTWave MP2110A is designed to meet these changing needs, with high-speed sampling to shorten measurement times and a high-sensitivity error detector performance to improve yields to reduce optical modules and devices production costs.

Instead of requiring two separate instruments for measuring the BER and analysing eye patterns, the MP2110A supports simultaneous measurements, saving equipment installation space. Maximum sampling speed has been increased to 250ksamples/s, reducing eye pattern analysis times for eye mask tests by 75 per cent compared to earlier instruments, says the company. It supports options for expanding the built-in bit error rate tester (BERT) to four channels at up to 28.2Gbit/s, and the built-in sampling oscilloscope to two channels. As a result, the MP2110A can perform simultaneous TRx BER measurements of multi-channel optical modules, such as QSFP28, and simultaneous two channel eye pattern analyses, dramatically reducing measurement times by up to 65 per cent compared to previous measurement systems, claims the company.

Minimum sensitivity is -15dBm (typical SMF), and the sampling oscilloscope optical interface supports accurate eye pattern analysis of signals that have been attenuated by switches, for example. PPG jitter performance is just 600fs rms (typical) and ED sensitivity is 25mV (typical) to support measurement with better performance than the device under test (DUT).
