Dual Fiber-optic Patch Cords

-
A Dual Fiber-optic Patch Cord has two optically isolated fibers. One side ends with a dual ferrule guiding pin or a guiding socket connector. The other side of the patch cord can also end with a dual ferrule connector or with separate FC connectors for each fiber. The Dual Fiber-optic Patch Cord can transmit independent optical signals when used with a Separate Light Path 2x2 Fiber-optic Rotary Joint. Using dual patch cords with a 1x2 Fiber-optic Rotary Joint is optically more efficient but more expensive than using a branching patch cord with a 1x1 Fiber-optic Rotary Joint.
