FBT Coupler Splitter 1×N / 2×N | Low Cost, Custom Split Ratios, OEM/ODM Support

FBT (Fused Biconical Taper) coupler splitters are passive optical devices fabricated by fusing and stretching multiple fibers into a tapered region, enabling the splitting or combining of optical signals. Ideal for PON, CATV, FTTH, LAN/WAN, and optical sensing applications, these splitters offer low cost, flexible split ratios, and ease of integration.

Why Choose Our FBT Coupler Splitters

Low Cost & Efficient: Economical manufacturing via fiber fusion makes FBT couplers a cost-effective choice for low- to medium-channel applications. 

Adjustable Split Ratios: Real-time fusion process allows flexible customization of splitting ratios (e.g., 1×2, 1×4, 2×2, or tree/star configurations). 

Wideband Operation: Supports dual or multiple windows like 1310/1490/1550 nm, depending on fiber type.

Compact & Reliable: Available in ABS box, steel tube, cassette or bare forms, offering durable housings for field deployment. Meets Telcordia GR-1209/1221 and RoHS standards. 

Product Configurations

FBT Couplers 1×N (1 input, N output) for standard splitter deployments.

FBT Couplers 2×N (dual-input) for redundancy or bidirectional signal distribution.

Available in steel tube, ABS box, cassette, or loose fiber formats for flexible installation environments.

Specifications Overview

Split Ratios: Common options include 50/50 split (1×2), 1×4, 1×8, and custom ratios via cascading tree/star designs.

Wavelength Options: Typically available for 1310 nm, 1490 nm, 1550 nm, and wide-band variants. 

Insertion Loss: Usually low; example FBT 50/50 ABS module IL ~3.8 dB (typical).

PDL & Return Loss: Polarization-dependent loss typically ≤0.2 dB; return loss ≥50 dB.

Operating Temp: –40 °C to +85 °C.

Applications

FTTH / GPON / EPON access networks—splitting feeders to multiple ONUs.

CATV distribution systems in building or campus networks.

LAN, WAN and general optical signal branching in telecom equipment.

Cost-sensitive, low-output-count deployments like MDU or campus links.
