The items came quickly, worked instantly. The beauty of a Bidi is that it handles a network connection on only one fiber. Bidi stands for bidirectional if you don’ T know. It can send and receive on one fiber using two wavelengths. So if fiber channels are limited these are the answer, speed and latency seemed just fine with the one conductor.

I am using these in Netgear.
They just work! ~1G throughput without any tweaking required.
