LC to LC OM1 Multi-mode Fiber Optic Patch Cord
This 'LC to LC OM1 Multi-mode Fiber Optic Patch Cord' is a critical component for building efficient, reliable fiber optic networks.
- LC denotes the small-form-factor (SFF) LC duplex connector, specifically engineered for high-density cabling environments to maximize rack and panel space utilization.
- OM1 refers to the multimode fiber grade, featuring a classic 62.5/125µm core/cladding diameter. It remains the go-to choice for legacy building and campus backbone networks, supporting LED light sources and traditional Ethernet/Fibre Channel applications.
The LC to LC OM1 patch cord remains a reliable, standards-compliant, and cost-efficient workhorse for maintaining and extending legacy multi-mode fiber infrastructure. Whether upgrading enterprise networks or supporting high-density AI-ready data centers, selecting a supplier with proven quality systems and scalable capacity ensures both performance and long-term investment protection.
Component Parts & Materials
The patch cord comprises four precision-engineered components:
| Component | Material | Function |
| Optical Fiber (Core) | High-quality 62.5/125µm OM1 graded-index multimode fiber (silica glass) | Physical transmission medium for optical signals. |
| Tight Buffer (Coating) | LSZH (Low-Smoke Zero-Halogen) or PVC | Provides primary mechanical protection and flame retardancy. |
| Strength Member | Aramid yarn (Kevlar®-equivalent) | Delivers superior tensile strength, preventing fiber stress during pulling and installation. |
| Outer Jacket | Orange flame-retardant material (LSZH, OFNR, or OFNP rated) | Orange is the industry-standard color code for OM1 fiber; provides environmental and abrasion protection. |
Product Specifications & Features
- Connector Type: LC to LC Duplex – both ends feature LC interfaces with zirconia ceramic ferrules ensuring precision alignment and ultra-low insertion loss.
- Structural Design:
- Duplex (Zipcord) construction: Two fibers side-by-side support bidirectional transmission; labeled A/B for easy polarity identification.
- Polarity: TIA/EIA compliant, typically Type A (straight-through) for standard equipment interconnection.
- Performance Highlights:
- Low Insertion Loss: Standard ≤0.3dB; premium grades achieve as low as 0.15dB.
- High Return Loss: ≥30dB (UPC polish), minimizing back-reflection and signal distortion.
- Durability: Supports ≥500 mating cycles with performance variation ≤0.2dB.
- Operating Temperature: -20°C to +70°C (commercial grade).
