Looking for a cost-effective and reliable solution to split optical signals in fiber optic networks? Our 1×2 FBT Splitter is the ideal choice for singlemode fiber applications that require precise optical signal distribution across two output ports. Manufactured with high-quality SMF-28 fiber and available with various connector options, this fused biconic taper (FBT) splitter is a popular solution in FTTH, CATV, LAN, and PON networks.
Engineered for low insertion loss, high reliability, and wide operating wavelength ranges, the 1×2 FBT splitter is well-suited for both indoor and outdoor environments. It features a compact design, excellent performance stability, and customizable configurations to meet a variety of optical distribution needs.
What is a 1×2 FBT Splitter?
The 1×2 FBT Splitter is a passive optical component used to split or combine optical signals. In the FBT (Fused Biconic Taper) fabrication process, two or more optical fibers are fused together by applying heat while being stretched and tapered under precise control. This fusion allows the input signal to be evenly or unevenly distributed between two output fibers.
The 1×2 configuration consists of one input and two output ports, making it ideal for point-to-multipoint applications such as distributing a single optical signal to multiple endpoints or monitoring systems.
Key Features of the 1×2 FBT Splitter
- Low Insertion Loss & Polarization Dependent Loss (PDL)
Ensures consistent signal strength and low transmission loss across both output channels. - Wide Wavelength Range (1260nm – 1650nm)
Compatible with most singlemode applications, including 1310nm and 1550nm wavelengths. - Compact & Rugged Design
Space-saving package options with enhanced mechanical stability for long-term field use. - High Channel Uniformity
Maintains a consistent splitting ratio across outputs. - Customizable Connectors & Ratios
Supports SC/APC, SC/UPC, LC, FC, and other connector types. Split ratios from 1/99 to 50/50 available. - Excellent Reliability
High temperature resistance and durability for long-term use in harsh environments.
Applications
The 1×2 FBT Splitter is widely used in:
- Fiber to the Home (FTTH) networks
- Passive Optical Networks (PON/GPON/EPON)
- Local Area Networks (LAN)
- CATV systems
- Test equipment and laboratories
- Signal monitoring and sensing systems
Its compact size and adaptability make it suitable for use in splice trays, wall-mount boxes, enclosures, and patch panels.
