FLYPROFiber LC to LC OM3 1M/3ft
The FLYPROFiber LC to LC OM3 patch cable in a compact 1 meter length is designed for high-density Ethernet applications, data centers, and premise installations. This duplex link supports 10Gb Ethernet connections and is suitable for connecting 10G SR, 10G LRM, and SFP+ transceivers. Its OM3 multimode construction provides broad compatibility with standard OM3 cabling systems, making it a versatile option for modern networks.
Key specifications emphasize stability and low loss: insertion loss is kept under 0.3 dB, and return loss is at least 30 dB. The 50/125 μm fibre and cladding are engineered for bending insensitivity, helping minimize signal degradation in tight cabinet layouts. The LSZH jacket enhances safety and reduces in-building risk, especially in dense data center racks.
FLYPROFiber LC to LC OM3 2M-6Pack (OM3 Multimode)
This 2-meter, six-pack of LC to LC OM3 multimode patch cables is ideal for high-density installations where multiple server blades or switch chassis require short, reliable interconnects. The cables feature a bend-tolerant 7.5 mm minimum bend radius and a low insertion loss profile (≤0.3 dB) with high return loss (≥30 dB), ensuring stable performance in crowded racks and SAN cabinets. The LSZH jacket helps improve safety in shared spaces and reduces hazard exposure during installation.
With 10G/40G Ethernet suitability, these patch cables pair well with 10G SR/10G LRM transceivers and SFP+ modules. The design intends straightforward interoperability with standard OM3 cabling systems, making it easy to scale networks without replacing existing infrastructure.
FLYPROFiber LC to LC OM4 2M
The OS2-equivalent OM4 patch cable in a 2-meter length offers higher bandwidth and lower attenuation for high-speed networks. Its 40/100Gb compatibility supports QSFP+/SFP+ transceivers, making it a strong choice for data centers and enterprise networks looking to future-proof interconnects. The cable’s LSZH jacket delivers fire-safety benefits in indoor environments, and the 7.5 mm bend radius ensures resilience in tight cable management layouts without sacrificing performance.
YUTIANHOME 165ft/50m OM3 Outdoor Armored LC to LC
This long, outdoor-rated LC to LC patch cable is built for rugged environments. The Industrial TPU jacket provides strong tensile strength, water resistance, UV exposure protection, and temperature resilience from -20°C to 70°C. The armor and glass fiber yarns offer dual protection against rodents and physical damage, making it suitable for outdoor deployments, temporary networks on construction sites, or any installation requiring durable, weather-resistant cabling. It supports multimode OM3 performance, enabling 10G/40G Ethernet connections over moderate distances.
Buying Guide: Key Purchase Considerations
- Fiber type and bandwidth: Choose OM3 or OM4 for multimode applications demanding 10G/40G/100G Ethernet. OM4 offers higher bandwidth and improved performance over longer runs.
- Jacket material and environment: LSZH jackets are safer for indoor installations, while TPU armoring suits outdoor or industrial settings. Consider temperature range, flexibility, and bend radius for cabinet layouts with dense fiber routes.
- Length and routing: Short patches (1–2 m) are common inside racks, while longer runs (50 m) suit cross-room or data-center backbone links. Matching length to the link budget helps minimize unnecessary attenuation.
- Connectors and compatibility: LC-LC duplex cables pair with SFP+/SFP transceivers and standard OM3/OM4 cabling systems. Ensure transceiver compatibility and forestall mismatch losses.
- Durability factors: Low insertion loss and high return loss improve transmission stability, especially in high-density environments. Consider bend radius to avoid macrobending losses in cabinets.
- Outdoor and armored options: For exposed or rugged installations, armored or armored-tube designs reduce damage risk but may cost more and be stiffer.
- Number of cables: In high-density cabinets, multi-pack options (e.g., 6-pack) simplify deployment and improve cable management efficiency.
Overall, LC to LC fibre patch cables with OM3 or OM4 multimode cores, LSZH jackets, and proper bend radius are well-suited for modern data centers and enterprise networks seeking reliable, scalable connectivity. For outdoor or harsh environments, armored variants provide added protection at the cost of flexibility.
