Fiber optics Coupler

Fiber optic coupler is an fiber optic equipment with at least three or more fiber optic ends; the function of fiber optic coupler is to split the input fiber optic light into several parts to the output fiber ends at a certain ratio. The fiber optic coupler can be made with single mode fiber optic cable or multi mode fiber optic cables.

There are single window fiber optic couplers and dual window fiber optic couplers. Single window means single wavelength with a narrow wavelength window, dual window fiber optic couplers is with two wavelengths with a wide wavelength window for each.

Fiber optic coupler specification include the numbers of input and output ports, usually input is one cable port while output is many cable ports,for example ,a 1X2 60:40 ratio fiber optic coupler can split a beam of the fiber optic light into two parts at the ratio of 60:40 and sent separately into the other two fibers on the other side of the fibre optic splitter. the fiber optic couplers can be with different kinds of fiber optic connectors, usually it is with SC, SC/APC,FC,FC/APC,ST, or LC fiber optic connectors.

Input and output cables length is also optional, for example, 1 meter input cable length and 1 meter for each of the output cable length.

Insertion loss refers to the attenuation caused by insertion of fiber optic components.Huihong fiber optic couplers and fiber optic splitters are available in various styles, sizes, connector types, splitting ratios, and wavelength. High quality ,good looking and fast delivery.

we also supply planar fiber optic couplers.Planar technology is the latest in passive fiber optic equipment manufacturing. It adopts semiconducter fabrication techniques to build compact fiber-optic devices.

Features: Single mode and Multimode fiber couplers Various connector types optional Various splitting ratios from 50:50 to 1:99 Multiple packaging options(Box type,stainless steel type,module type) PC, UPC and APC connector polish types optional
