Fiber Optic SplitterSignal Distribution
PLC and FBT splitters from 1×2 to 1×64 — GPON/EPON compatible, multiple package options.
Overview
A fiber optic splitter divides a single optical input into multiple outputs — or combines multiple inputs into one — without any electrical power. It is the key passive component in every PON (Passive Optical Network) deployment, enabling one OLT port to serve dozens of subscribers. TTI Fiber supplies both PLC (Planar Lightwave Circuit) and FBT (Fused Biconical Taper) splitters to match every network topology, budget, and split-ratio requirement.
Our PLC splitters use semiconductor-grade silica waveguide technology for uniform splitting across the full 1260–1650 nm wavelength window, compatible with GPON, EPON, XGS-PON, and 10G-EPON. Split ratios range from 1×2 through 1×64. Package options include bare fiber (steel tube), ABS box, LGX cassette, mini plug-in module, and 1U rack-mount tray.
FBT splitters remain cost-effective for low-ratio splits (1×2 to 1×4) and wavelength-selective applications such as CATV 1310/1550 nm WDM. Every fiber optic splitter is 100% factory-tested for insertion loss, uniformity, return loss, and directivity, backed by a 25-year design life and ISO 9001 quality management.

Configuration guide
Choose a Fiber Optic Splitter by installation need
Choose the split ratio from the number of end points first, then confirm wavelength window, connector polish, enclosure format, and the loss allowance in the complete link budget. PLC is the general choice for uniform PON splitting; FBT remains useful for low-ratio or wavelength-specific work.
| Project need | Starting configuration | Why it fits | Related model |
|---|---|---|---|
| Low-ratio or wavelength-specific split | FBT, 1×2 or 2×2 | Use an FBT splitter when the design is a small split and the project calls for its 1310/1490/1550 nm options. | FBT Splitter |
| Standard FTTH or FTTB branch | PLC, 1×8 | A 1×8 PLC module is a practical starting point for uniform PON distribution across the documented 1260–1650 nm window. | PLC Splitter 1x8 |
| Higher subscriber density | PLC, 1×32 or 1×64 | Use a higher split ratio only after checking insertion loss against the available optical budget and the intended OLT/ONU design. | PLC Splitter 1x32 |
| Redundant OLT input architecture | PLC, 2×N | A dual-input PLC configuration supports protected or redundant input designs where a single-input module is not appropriate. | PLC Splitter 2xN |

Frequently Asked Questions
PLC (Planar Lightwave Circuit) splitters use waveguide chip technology for precise, uniform splitting — best for high-ratio splits (1×8 and above). FBT (Fused Biconical Taper) splitters fuse two fibers together — simpler and more cost-effective for low-ratio splits (1×2, 1×4) and wavelength-selective applications.
Bare fiber (steel tube) for splice closures and tight spaces. ABS box for wall-mount distribution boxes. LGX cassette for rack-mount patch panels. Mini plug-in module for compact ODF trays. Choose based on your installation location and access requirements.
Yes. Our PLC splitters operate across the full 1260–1650 nm window, supporting simultaneous GPON data (1310/1490 nm) and CATV video overlay (1550 nm) without the need for separate splitting stages.
A 1×8 PLC splitter has a typical insertion loss of approximately 10.5 dB (maximum 10.8 dB per ITU-T G.671). This includes the theoretical splitting loss of ~9.0 dB plus excess loss of ~1.5 dB.
Yes. We manufacture 2×4, 2×8, 2×16, 2×32, and 2×64 dual-input PLC splitters for redundant OLT architectures and protection switching applications.
