Passive Optical Components — China Supplier & Manufacturer
Passive optical components require no power and form the optical distribution network (ODN) between the OLT and the ONT. Fiber Optic Telecom (FOT) supplies PLC splitters, patch cords, fast connectors, adapters and distribution boxes for FTTH, PON, CATV and enterprise fiber networks.
Model Comparison
| Model | Type | Key specification | Configuration |
|---|---|---|---|

| Fiber Optic Patch Cords (Jumpers) | Patch cord | IL ≤0.2 dB, RL >50 dB | SM/MM, FC/SC/LC/ST |
| Fiber Fast Connectors | Connector | IL ≤0.3 dB, RL APC ≥60 dB | SC/LC, UPC/APC |
| Fiber Optic Adapters | Adapter | IL ≤0.2 dB | Simplex/Duplex/Hybrid |
| Fiber Optical Distribution Box | Enclosure | 2–72 cores | Wall/pole mount |
Specifications reflect the published catalog. Confirm the exact model, optional features and compatibility with FOT before ordering.
How to Choose
- Match the splitter ratio to your PON design — GPON typically uses 1:32 or 1:64; 1:128 is the practical maximum. Add the splitter insertion loss to your optical budget.
- Choose the right connector polish — UPC (≥50 dB return loss) for data, APC (≥60 dB) for CATV and PON to minimize back-reflection.
- Select single-mode vs. multimode — single-mode (G.652A/G.657A) for long-reach PON/FTTH; multimode only for short data-center links.
- Pick the packaging for the location — mini-tube and ABS splitters fit distribution boxes; cassette and rack-mount splitters suit ODF frames; outdoor boxes need UV-resistant sealing.
- Use fast connectors for drop cables — field-installable fast connectors avoid splicing in FTTH/FTTR drops; verify the cable diameter (0.9/2.0/3.0 mm) before ordering.
Frequently Asked Questions
Equipment Buyer Questions
What is a PLC splitter?
A Planar Lightwave Circuit splitter divides one optical input into multiple outputs on a quartz substrate, used in PON/FTTH to share one OLT port among many subscribers.
What insertion loss should I expect?
Listed PLC splitters specify 4.0 dB (1×2) to 21.0 dB (1×64); add ~0.5 dB margin for connectors and splices in your optical budget.
What is the difference between UPC and APC connectors?
UPC has a flat blue polish (return loss ≥50 dB); APC has an angled green polish (return loss ≥60 dB) that suppresses back-reflection — required for CATV and recommended for PON.
Do FOT distribution boxes support outdoor mounting?
Yes — listed distribution boxes are UV-resistant and weatherproof, supporting wall and pole mounting for outdoor FTTH/PON deployment.
Can FOT supply custom splitter ratios and packaging?
PLC splitters are available in 1×N and 2×N from 1:2 to 1:64 in mini-tube, ABS, cassette and rack-mount packaging. Confirm the configuration and quantity with FOT.
