Fiber Optic ST Connector Coupler 1 × 2 Ratios Wideband Optical
Couplers
Optic Coupler Brief Introduces:
Singlemode Couplers 1X2 and 2X2 offer very low insertion loss, low
polarization dependence, and excellent environmental stability.
Accurate coupling ratio's from 50/50 to 1/99 are available with
very tight uniformity. The Singlemode Standard Coupler components
perform power splitting and monitoring functions in all kinds of
optical communication systems.
Geehe's Fiber Couplers with more stability, and widely used by
brands and brand manufacturers, also get Brazil Anatel Certificate,
tapered (FBT) technology, and are fully compliant with Telcordia
GR-1209/1221 standards for network applications.
Fiber Optic Coupler Features& Benefits:
Low Excess Loss
High Stability And High Reliability
Ultra-low PDL and temperature sensitivity
Low insertion loss over entire bandwidth and temperature (typical
IL change <±0.1dB)
- Low PDL
