Bit Error Rate & BERT Meter (part2)

Bit Error rate control & Bit Error testing (BERT) is crucial to network performance especially for Ethernet, SDH, DWDM and OTN Networks that are based on Optical transmission.   What is a BERT Meter (BER Tester)? A BERT Meter is an electronic device that is used to measure the Bit Error Rate. There are many equipment vendors that manufacturer that sell BER Testers. Some of the popular companies are JDSU, Anritsu and EXFO. However, their prices & features vary a lot. Below is one of the famous BERT Meter model as an example (courtesy JDSU).       How to Read More …

Bit Error Rate & BERT

Performance of the transmission system is of crucial importance to communication quality of the whole communication network. Good performance can be achieved through proper control over Bit Error Rate & BERT. The major factors affecting the performance of SDH transmission network includes bit error, jitter and wander. So, what are the Bit Errors? Why are they so important to control? Do the Bit errors affect my network performance? These are some of the questions that every network engineer and optical transmission engineer must know. Let’s dissect these questions & their answers one by one. “Bit Error is the amount of Read More …
