450～2400m SM MM PM Fiber optic reflectors
Fiber Bragg Grating Reflectors are engineered to reflect light back through the fiber when entering via connectors. These components can be used to create fiber interferometers or build low-power fiber lasers. They are particularly well-suited for accurately measuring back-reflection specifications in transmitters, amplifiers, and other optical devices.
Our fiber returners are available in single-mode (SM), polarization-maintaining (PM), and multimode (MM) fiber variants. The fiber ferrule features a protective silver-coated layer that delivers an average reflectivity of ≥97.5% across the 450 nm to maximum wavelength range. Encased in a φ9.8mm (0.39-inch) stainless steel housing, the ferrule's end connects to either a 2.0mm narrow-pin connector (FC/PC, compatible with SM/PM/MM fibers) or an FC/APC connector (compatible with SM/PM fibers). For PM fibers, the narrow pin is precisely aligned with the fiber's slow axis. Each jumper cable includes a protective cap to prevent dust or contaminants from adhering to the ferrule's end.
