Features
full duplex over single fiber; dc to 160 mHz link bandwidth; link budgets of 2 km [1.25 miles]
or greater; 40 dB isolation; other transmitter/receiver configurations, housings, and connector
options available
Duplexers contain two devices per module so they may communicate in opposing
directions simultaneously and independently. May be used to multiplex two signals to a
single fiber and where dual fiber solution is neither possible nor economical.
