Core Differences Between FBT and PLC Splitters
FBT (Fused Biconical Taper) Splitters and PLC (Planar Lightwave Circuit) Splitters are two mainstream passive components in optical communications. Their core differences lie in manufacturing process, performance, cost, and application scenarios, as detailed below:
| Comparison Item | FBT Splitter | PLC Splitter |
| Manufacturing Principle | Multiple fibers are fused and tapered; power is split in the coupling region | Based on quartz substrate, using semiconductor lithography and etching to integrate optical waveguides for power splitting |
| Operating Wavelength | Supports only 850nm, 1310nm, 1550nm; wavelength-sensitive | Full-band coverage: 1260–1650nm; compatible with CWDM/DWDM, no wavelength limitation |
| Splitting Capacity | Max 1×4; higher ratios require cascade (e.g., 1×8 = two 1×4 units) | Native support 1×2 to 1×64; stable at high channels without cascading |
| Splitting Uniformity | Poor; up to 1.5dB loss variation for 1×8, easy uneven splitting | Excellent; ≤0.5dB loss variation, highly uniform output |
| Size & Package | Mostly bare fiber or ABS box, relatively large (e.g., φ3×60mm) | Cassette type / ABS box / micro module, compact size, high integration |
| Cost | Low cost for low channels (1×2/1×4), mature process | High cost for low channels; obvious cost advantage for high channels (1×32/1×64) |
| Stability | Average; weak environmental resistance, medium long-term reliability | High; wide temperature range (-40℃~+85℃), strong anti-interference, high reliability |
Selection Guide
- For 1×2/1×4 low-channel applications with limited budget and fixed wavelengths (1310/1550nm only), choose FBT for high cost performance.
- For 1×8 and above high-channel applications, full-band support (including E-band), or long-term stability, choose PLC, ideal for FTTH and 5G networks.
- For standard cabinet deployment (19-inch rack, chassis), prioritize plug-in PLC splitters for compact size and easy maintenance.
Key Features & Benefits
Our FBT splitters are characterized by compact size, high mechanical reliability, cost-effectiveness, and excellent channel-to-channel uniformity. They are widely deployed in PON (Passive Optical Network) architectures to efficiently split optical signals for FTTH, FTTB, and broadband access applications.
