1x2 Fused Biconical Taper (FBT) Optical Splitter, Bare Fiber Termination

Product Description & Features

Overview

The 1x2 FBT splitter is a compact, high-reliability passive optical device designed to split a single input signal into two equal outputs using Fused Biconical Taper (FBT) technology. This model features bare fiber termination (no pre-installed connectors), offering flexibility for custom connectorization or fusion splicing during installation. Ideal for applications requiring low-loss, cost-effective signal distribution in fiber-optic networks.

Key Features

1. FBT Technology Advantages
   • Uniform Split Ratio: 1:2 division with
   • Low Insertion Loss: ≤0.3dB (typical), ≤0.6dB (max) per output for minimal signal degradation.
   • High Return Loss: ≥55dB to eliminate back reflections and ensure signal integrity.
2. Bare Fiber Design
   • Customizable Termination: No pre-installed connectors allow field installation of SC/APC, LC/APC, or other connector types.
   • Fusion Splicing Ready: Direct splice to patch cords or pigtails for permanent, low-loss connections.
3. Broadband Compatibility
   • Wide Wavelength Range: Supports 1260–1650nm for use in O-, E-, S-, C-, and L-band networks.
   • Singlemode Fiber: Optimized for G.652D/G.657A fiber types (ITU-T standards).
4. Compact & Robust Design
   • Small Form Factor: Space-efficient for dense installations in telecom cabinets or outdoor enclosures.
   • Heat-Resistant Sleeve: Protects the fusion-tapered region from thermal expansion or environmental stress.
5. Environmental Adaptability

   • Wide Temperature Range: Operating from -40°C to +85°C for harsh indoor/outdoor conditions.

   • High Humidity Tolerance: Resistant to moisture (5%–95% RH non-condensing).

Technical Specifications

Typical Applications

1. FTTH/FTTx Networks: Distribute signals to residential or business subscribers.

2. Local Area Networks (LANs): Split data traffic between servers or switches.

3. CATV/IPTV Systems: Branch video signals to multiple receivers.

4. Fiber Sensing Systems: Split light sources for distributed sensing applications.

Competitive Advantages

• Cost Efficiency: FBT technology reduces costs compared to PLC splitters for small split ratios.

• Field Flexibility: Bare fiber ends enable customization for unique connector requirements.

• High Stability: FBT process ensures consistent performance over time and temperature fluctuations.
