Multimode Fiber Optic Coupler

Fiber Optic Coupler (MM FBT Coupler ) are fabricated from Corning’s multimode fibers with core diameters of 50um ,62.5um or 100um. Standard multimode couplers are commonly used in short distance communications with LED sources operating at 1310nm or 850nm. Multimode couplers are wavelength independent over a broad range of wavelengths (600nm to 1610nm) with uniform modal power distribution launch condition, multimode tree/star couplers NX4(n=1,2,4) NX8(n=1,2,8) NX16(n=1,2,16) port ratios are available.

A fiber optic splitter is a device that splits the fiber optic light into several parts by a certain ratio. PLC splitters offer a better solution for larger applications. Waveguides are fabricated using lithography onto a silica glass substrate, which allows for routing specific percentages of light. As a result, PLC splitters offer accurate and even splits with minimal loss in an efficient package. PLC (Planar Lightwave Circuit) Splitters are Single Mode Splitters with an even split ratio from one input fiber to multiple output fibers. Available split counts are: 1xN and 2xN (N for 2, 4, 8, 16, 32, 64). PLC Splitters are available with 900µm loose tube singlemode fiber and terminated or unterminated as per your needs.
