China Optical Fiber Patch Cord Factory: Professional SC, FC, LC UPC/APC Connectors - Reliable Suppliers for Data Centers
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.
Core Definition & Function
It is a short-length optical fiber (typically 0.5m–10m) with standardized connectors attached to each end. 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.
Key Components & Structure
Optical Fiber Core
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 & Coating
Cladding (around the core) ensures total internal reflection, while a protective polymer coating prevents mechanical damage and moisture intrusion.
Strengthening Member
Materials like aramid yarn (Kevlar) or steel wire enhance tensile strength, resisting breakage during installation or handling.
Jacket
Outer sheath (PVC, LSZH, or OFNR/OFNP) provides additional protection and meets fire safety or environmental requirements.
Connectors
Pre-installed at both ends (e.g., SC, LC, ST, FC, MPO/MTP), polished (PC, UPC, or APC) to minimize insertion loss and return loss.
Critical Features
- 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℃ to +85℃, suitable for indoor (data centers, offices) or outdoor (telecom cabinets) use.
- Flexible Configurations: Customizable in length, fiber type (SMF/MMF), connector type, and jacket material to fit specific application needs.
Common Types & Classifications
- 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, etc.
- By jacket material: PVC (cost-effective, indoor use), LSZH (low smoke zero halogen, safe for public areas), OFNR/OFNP (flame-retardant, for vertical/riser applications).
Typical Applications
Data Centers
Connect servers, switches, and storage devices to patch panels, supporting high-speed Ethernet (10G/40G/100G).
Telecommunication Networks
Link base stations, OLTs (Optical Line Terminals), and ONUs (Optical Network Units) in PON/FTTH systems.
Enterprise & Campus Networks
Facilitate connections between network hardware in offices or industrial facilities.
Test & Measurement
Used in fiber optic testing setups to verify signal performance, insertion loss, and network integrity.
