Standard Multimode Fiber Coupler
A1XN optical splitter divides input optical power among multiple fibers at specified splitting ratios for different applications. Fused-biconical-taper (FBT) multimode couplers operate over600–1700nm. Performance can be tested at a user-specified center wavelength; standard products are tested at850nm or1300nm. The company offers FBT multimode couplers using50/125um,62.5/125um and105/125um fibers. Modal noise in multimode transmission can cause variations in test results and splitting ratios, so a low-coherence LED source is used to test their specifications.

Single-mode dual-wideband tree/star coupler / 1x4 - Operating wavelength: 1310/1550±40 (*1310/1550±20) or Customized Single-mode dual-wideband tree/star coupler / 1x4 - Maximum insertion loss: 7.3 (*7.2) Single-mode dual-wideband tree/star coupler / 1x4 - Uniformity: 1.6 (*1.4)
Fused biconical tapering brings two or more stripped fibers together in a defined arrangement, fuses them under high heat and simultaneously stretches them from both sides to form a special double-taper waveguide in the heated region for optical power coupling. A splitter/coupler distributes one optical input to multiple or two outputs, or combines multiple or two inputs into one output. Port configurations include X, Y, star and tree couplers.
