Couplers, Splitters & Combiners

1×3 Single Mode Monolithic Fiber Optic Coupler/Splitter

The FCTM series 1×3 Monolithic Single Mode Coupler utilizes Our fused biconical taper technology and compact packaging to deliver exceptional optical performance. With superior uniformity, low excess loss, and minimal polarization sensitivity — achieved through precision automated fabrication — this device is ideal for high-performance light splitting or combining across a broad wavelength range. Standard operating wavelengths include 1310 nm, 1490 nm, and 1550 nm, with dual- and triple-band configurations also available. The coupler is housed in a compact 3 mm diameter, 54 mm long tube, making it well-suited for space-constrained integration.
