Product description:
The Fiber optic Circulator from O/E Land Inc. is a non-reciprocating, one directional, 3-port devices which is used in variety of optical systems. The signal entering from Port 1 will exit from Port 2 with minimal loss, while a signal entering from Port 2 will exit from Port 3 with minimal loss. On the other hand, the device provides isolation of all the signals trying to propagate in opposite direction, i.e., from Port 2 to Port 1, and from Port 3 to Port 2 respectively. It is polarization-independent device, with low polarization-dependent loss (PDL). The optical path is epoxy free, thereby enabling relatively high-power applications. The isolator has compact design and features high stability and reliability. This product meets the Telcordia GR-1221-CORE reliability standard.
