For SONET/SDH equipment, the MP1590A accommodates tandem connection
and automatic protection switch (APS) tests.
It has built-in functions for concatenation mapping from OC-3c to OC-192c, BERT functions, as well as CID pattern and tandem connection
We showed that Lange couplers can be used as center stages of multisection couplers to realize a single coupler with a tight coupling coefficient by means of the tandem connection
Longer term, we believe Neutral Tandem can leverage its unique tandem connection
network to offer additional value-added services that could become significant revenue growth and profitability drivers," he added.
OTN networks are being implemented worldwide to provide robust and future-proof communications, with advantages such as Forward Error Correction (FEC), Tandem Connection
Monitoring (TCM), network scalability, as well as efficient and transparent transport of multiple types of signals including SONET/SDH and Ethernet.
In addition, the device can also monitor OTU2 section, path and tandem connection
performance, and relevant FEC error statistics.
In addition, the SONET/SDH processors support section and path trace, automatic protection switching (APS), and tandem connection
for improved SONET/SDH system reliability and monitoring.
