High-Quality Optical Fiber Patch Cords from China Suppliers - SC, FC, LC, UPC/APC | Reliable Factory Manufacturing
An Optical Fiber Patch Cord (also called fiber jumper or patch cable) is a fundamental passive component for connecting optical devices in fiber-optic networks, featuring pre-terminated connectors at both ends.
Its key role is to establish temporary or permanent optical connections between devices like transceivers, switches, patch panels, PLC splitters, and FAUs, facilitating signal transmission with minimal loss (typically 0.5m–10m in length).
The transmission medium, available in single-mode (SMF, 9/125 μm) for long-distance, high-bandwidth applications or multi-mode (MMF, 50/125 μm or 62.5/125 μm) for short-range, high-data-rate scenarios.
Cladding (around the core) ensures total internal reflection, while a protective polymer coating prevents mechanical damage and moisture intrusion.
Materials like aramid yarn (Kevlar) or steel wire enhance tensile strength, resisting breakage during installation or handling.
Outer sheaths (PVC, LSZH, OFNR/OFNP) meet safety needs. Pre-installed connectors (SC, LC, ST, FC, MPO/MTP) with PC, UPC, or APC polishing minimize loss.
- Low Insertion & Return Loss: Typical insertion loss <0.3 dB, return loss >45 dB (UPC) or >60 dB (APC), ensuring signal integrity.
- High Compatibility: Standardized connectors and fiber types match global industry specifications, enabling universal use.
- Mechanical Durability: Reinforced structure withstands bending, twisting, and repeated plug-unplug cycles (≥1000 times).
- Environmental Adaptability: Operates stably in temperatures ranging from -40°C to +85°C, suitable for indoor or outdoor use.
- Flexible Configurations: Customizable in length, fiber type (SMF/MMF), connector type, and jacket material to fit specific application needs.
- By Fiber Type: Single-mode Patch Cord (for long-haul communication, PON networks) and Multi-mode Patch Cord (for data centers, LANs).
- By Connector Type: SC-SC, LC-LC, SC-LC, ST-FC, MPO-MTP, and more.
- By Jacket Material: PVC (cost-effective, indoor), LSZH (low smoke zero halogen, public areas), and OFNR/OFNP (flame-retardant, vertical/riser).
Connect servers, switches, and storage devices to patch panels, supporting high-speed Ethernet (10G/40G/100G).
Link base stations, OLTs (Optical Line Terminals), and ONUs (Optical Network Units) in PON/FTTH systems.
Facilitate connections between network hardware in offices, campuses, or industrial facilities.
Used in fiber optic testing setups to verify signal performance, insertion loss, and overall network integrity.
