Fused Biconical Taper (FBT) Coupler/Splitter 2:98, 1:99, SMF28e Fiber - High Reliability from China Suppliers and Factory
Product description
Miniaturized Fiber Optic Coupling Devices feature compact size, excellent performance, and convenient connectivity:
- Compact Size: Miniaturized design with significantly reduced dimensions. Coupler size can be as small as diameter 2.4mm, length 35mm.
- Low Insertion Loss: Insertion loss is typically low, often ≤0.2dB. Helps reduce optical signal energy loss during coupling, maintaining signal strength and transmission quality.
- High Return Loss: High return loss, ≥50dB for UPC type, ≥60dB for APC type. Effectively reduces optical signal reflection, minimizing interference from reflected light, and improving system stability and reliability.
- High Compatibility: Good compatibility with different types of optical fiber.
- Strong Environmental Adaptability: Complies with industry standards like Telcordia GR-1221. Operates stably from -40°C to 85°C, exhibiting good environmental adaptability to meet various application scenario needs.
Product Applications
- Optical fiber communication system
- Cable TV
- Passive optical network
