The F-SMM900 Passive Dual-Clad Fiber is a passive, dual-cladding, Multi-Mode (MM) fiber that combines both Single-Mode (SM) and multi-mode fiber characteristics within a single fiber. The fiber has a germano-silicate single-mode core, a pure silica inner cladding to guide the pump light and a fluorine-doped secondary cladding to give outstanding power handling over a full range of environmental conditions. The fiber does not rely on a low index polymer coating, so it can be stripped, cleaved and spliced like a standard telecoms fiber, without the need to apply a low index recoat material.
F-SMM900 has been designed specifically to be used in conjunction with Fibercores Dual-Clad Erbium/Ytterbium Doped Fiber (F-CP1500Y), Multi-Mode Pump Fiber (F-MM105) and Isolating Wavelength Division Multiplexer (F-CP-IWDM). In order to minimize losses throughout the system and maximize efficiency, the optical characteristics of these fibers have been matched for high splice compatibility.
