Low PDL Flame-fused Optical Fiber Directional Couplers For CATV
System
Optic Coupler Brief Introduces:
Fiber Optic FBT splitter is a type of optical power management
device that is fabricated using Fused technology, which features
small size, high reliability, cheap cost, and good
channel-to-channel uniformity and is widely used in PON networks to
realize optical signal power splitting.
As the Top manufactures of fiber optic couplers, Geehe's equipment,
and Test equipment are all imported from Japan, more precision, the
workers with 15 years experience, the products are high stability
and reliability.
Fiber Optic Coupler Features& Benefits:
- Thermal stability of parameters
- Low insertion and polarization-dependent losses
- Wide range of housings and fiber connectors
- Unlimited choice of power split ratio and unusual operating range
- Versions optimized for full 1260-1650 nm band available
- Possible custom solutions
- Test reports with a full spectral profile of attenuation available
on demand
