Product Description
The Kerns Technology Multi-mode 1xN Fused Taper Coupler is a high-performance passive optical component designed to split 1 input multi-mode optical signal into N outputs (or combine N signals into 1) via fused taper technology. Optimized for 850nm/1310nm (or dual-band 850/1310nm), it supports flexible port counts (1x2, 1x4, etc.) and custom split ratios (1:99 to 50:50), with OM3/OM4 multi-mode fiber compatibility.
With low insertion loss, uniform signal distribution, and compact packaging options (e.g., φ3.0×L54), this coupler operates reliably in short-distance, high-bandwidth systems, making it a core component for data centers, multi-mode sensing, and optical signal distribution.
Product Features
1. Multi-mode & Dual-Band Compatibility
Supports 850nm/1310nm (or dual-band 850/1310nm) and OM3/OM4 50/125μm/62.5/125μm multi-mode fibers—matches mainstream multi-mode system specifications.
2. Flexible 1xN Configuration
Available in 1x2, 1x4, 1x8 (or custom N) port counts, with split ratios from 1:99 to 50:50 (uniform/non-uniform) to fit diverse signal distribution needs.
3. Low Loss & Uniform Performance
Typical insertion loss: ≤0.5dB (1x2, 50:50) minimizes signal attenuation.
Split ratio tolerance: ±4% ensures consistent signal power across output ports.
4. Compact & Customizable Design
Multiple packaging options: Small-form-factor (e.g., φ3.0×L54) or standard (90209.5mm) to fit space-constrained setups.
Tailored options: Custom fiber types, connectors (FC/SC/LC), and tail fiber lengths.
Product Applications
This multi-mode 1xN coupler is widely used in:
Data Centers: Short-distance (≤550m) 10Gbps/40Gbps multi-mode fiber interconnects (e.g., server-to-switch links).
Multi-mode Fiber Sensing: Signal distribution in 850nm/1310nm-based temperature/strain sensing systems.
Optical Signal Distribution: Multi-port signal routing in industrial control and monitoring equipment.
Test & Measurement: Signal splitting for multi-channel optical characterization tools.

FAQs
Q1: What’s the advantage of multi-mode fused couplers?
A1: They enable high-bandwidth (up to 40Gbps) signal distribution in short-distance (≤550m) systems, with lower cost and easier termination than single-mode alternatives—ideal for data centers.
Q2: Can I customize the port count and split ratio?
A2: Yes. We offer standard 1x2/1x4/1x8 configurations, and can design custom N-port couplers with split ratios (e.g., 20:80) to match your system’s signal needs.
Q3: How do connectors affect performance?
A3: With connectors, insertion loss increases by 0.3dB, and return loss decreases by 5dB. We provide factory-terminated connectors (FC/SC/LC) for optimal compatibility.
Q4: What’s the maximum bandwidth supported?
A4: It supports up to 40Gbps (OM4 fiber, 850nm, ≤150m) and 10Gbps (OM3 fiber, 850nm, ≤300m)—matches mainstream multi-mode communication standards.
