Single-mode coupler module box

1x3 / P-Typical Excess Loss: 0.4 dB 1x3 / P - Maximum insertion loss: 5.6 dB 1x3 / P-Uniformity: 0.8 dB

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.

Operating Wavelength: 1270/1310/1490/1550/1620/single window/dual window/full band Return Loss: ≥50/55 Operating Temperature: −5~+70 ℃

OE photonics' MxN fiber star coupler is a customized waveguide-based device widely used in passive optical modules, CATV, and related communications.

Return loss: max:55 dB Directivity: max:60 dB PDL: max:0.2 dB

The main specifications of OE photonics' polarization-maintaining fiber coupler are listed below.

Operating Wavelength: 1310 or 1550 or customized Return Loss [Excluding connectors; Adding connectors reduces RL by 5dB]: ≥50 dB Optical Power: max:500 mw

OE photonics' polarization-maintaining coupler/splitter uses fused-biconical-taper or planar-waveguide power splitting. PM fiber transmits two orthogonal linear polarizations stably while maintaining their states. It is widely used in WDM and FTTx systems.
