Specifications of Fiber Optic Splitter Box

Fiber optic splitter boxes are passive devices that divide optical signals from a single input into multiple outputs, available in 1×N and 2×N models with PLC or FBT technology, supporting various split ratios, connector types, and packaging formats.

Overview

A fiber optic splitter box is a passive optical component used to distribute optical signals from a central office or optical line terminal (OLT) to multiple endpoints, such as optical network units (ONUs) or terminals (ONTs) in FTTH networks . These devices are essential for point-to-multipoint communication and are widely used in GPON, XGS-PON, and other PON standards .

Types of Splitters

1. PLC (Planar Lightwave Circuit) Splitters
   • Provide uniform splitting, ideal for high split ratios (1×8, 1×16, 1×32)
   • Compact and suitable for large-scale deployments
   • Low insertion loss (≤3.8 dB) and low polarization dependent loss (≤0.2 dB)
   • Wide operating wavelength: 1260–1650 nm
   • Can be packaged in ABS plastic modules, mini modules, or bare fiber formats
2. FBT (Fused Biconical Taper) Splitters
   • Cost-effective for small split ratios (1×2, 1×4)
   • Slightly less uniform than PLC, but suitable for simpler networks
   • Typically used in legacy or low-density applications

Models and Configurations

• 1×N and 2×N Splitters: Single or dual input fibers split into multiple outputs
• Split Ratios: Customizable, e.g., 1:2, 1:4, 1:8, 1:16, 1:32
• Connector Types: SC, LC, FC in APC or UPC styles
• Packaging Formats:
  • Bare fiber for integration into splice trays
  • Wall-mounted or optical distribution boxes
  • Plastic cassette modules with ruggedized fiber jackets (2.0 mm)
• Environmental and Mechanical Specs:
  • Operating temperature: -40°C to 85°C
  • High return loss, excellent channel-to-channel uniformity, and mechanical stability
  • Compliance with Telcordia GR-1209-CORE and GR-1221-CORE standards

Fiber Optic Distribution Boxes

Splitter boxes are often integrated into fiber optic distribution boxes, which provide:

• Splicing, splitting, and distribution in a sealed, IP68-rated enclosure
• Cable clamping, fixation, and storage for feeder and distribution fibers
• Protection against environmental factors while maintaining network reliability

Applications

• FTTH and FTTX deployments
• LAN, WAN, and metro networks
• CATV and telecommunications networks
• High-density network expansions requiring scalable and reliable optical distribution

Key Considerations

When selecting a fiber optic splitter box, consider:

• Required split ratio and number of outputs
• Type of splitter (PLC for high uniformity, FBT for cost efficiency)
• Connector type and packaging format for network integration
• Environmental conditions and compliance with industry standards
• Customization options for labeling, logo, or OEM requirements Fiber optic splitter boxes are versatile, scalable, and essential components for modern optical networks, providing efficient signal distribution while minimizing fiber usage and network footprint.
