Single Mode Dual Window 1310& 1550nm 1×4 FBT Fiber Optic FC Coupler
Optic Coupler Brief Introduces:
Fiber Fused Couplers / Splitters include wideband fused fiber
couplers, polarization-insensitive miniature circulators, and fused
single-mode wavelength division multiplexers.
MMFC series multi-mode single-window wideband fused fiber couplers
are highly stable for multiport optical signal splitting. SWFC /
DWFC series fused single or dual window wideband fiber 1x2 (2x2)
couplers provide accurate optical signal coupling and splitting
over a wide bandwidth with high performance and high reliability.
MIOC 3- or 4-port polarization-insensitive miniature circulators
feature excellent optical characteristics over a wide wavelength
range. SWD fused single-mode wavelength division multiplexers are
manufactured using fused biconical taper technology.
