1X2 Steel Tube Type 1310 / 1490 / 1550nm Fiber Optic FBT Coupler
FBT Coupler Description
Fiber Optic FBT splitter is a type of optical power management device that is fabricated using Fused Biconical Tape Technology.
It 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.
SUNET provides whole series of 1xN and 2xN spliiter products that are tailored for specific applications .All products meet GR-1209-CORE and GR-1221-CORE.
The single mode standard coupler features low excess loss, high stability and reliability. It is built by asymmetric coupling technique. The operating bandwidth of this normal coupler is expanding to ±40nm, and the ultra broadband coupler is expanding to ±80nm. The DWC has the same coupling ratio on both 1310nm and 1550nm communication windows, and with low excess loss and low PDL. DWC are widely used for communication systems, fiber optic cable coupler CATV, and FTTH.
FBT Coupler Feature
1. Low Excess loss
2. Low PDL
3. Environmentally stable
4. Good Thermal Stability
FBT Coupler Application
1. Long-haul Telecommunications
2. CATV Systems & Fiber Optic Sensors
3. Local Area Network
