Product Details
Fiber Optical Coupler
The coupler is a detachable connection device between the optical
fiber and the optical fiber. It precisely connects the two end
faces of the optical fiber, so that the optical energy output of
the transmitting fiber can be coupled to the receiving fiber to the
maximum extent, and make it intervene in the optical link so as to
minimize the impact on the system. The coupler and optical fiber,
also divided into single mode and multi-mode two, its role is to
achieve optical signal division and circuit, or used to extend the
fiber link components, the coupler can convert the optical signal
into electrical signal, the multi-mode signal coupling into single
mode signal, belonging to the field of optical passive components.
Some people will also call the coupler adapter, connector, flange,
etc.
