Fiber Optic Cables

Choose single-mode (SMF) for long-distance, high-bandwidth links and multimode (MMF) for shorter runs inside buildings; match the cable to the transceiver or equipment specifications and the intended distance and bandwidth requirements

Common connectors include LC, SC, ST, and MPO/MTP; pick the connector that matches your network devices or use adapters/patch panels to convert between types, and ensure ferrule alignment and polish type are compatible for low loss

OM3/OM4 are multimode grades optimized for higher data rates over specified distances, while OS2 is a single-mode grade with low attenuation for long runs; check attenuation (dB/km), modal bandwidth, and launch conditions to verify the cable meets your distance and bandwidth needs

Select indoor-rated cables for in-building use and outdoor or armored cables for direct-burial or riser/duct installations; follow the specified minimum bend radius, protect against moisture and UV if outdoors, and account for tensile load limits during pulls

Prices vary by fiber type, length, connectorization, and armoring; budget options and simple patch cables are generally under $50, while long runs, pre-terminated trunks, and armored or MPO assemblies can range from tens to several hundred dollars, with many products averaging around the low triple digits

Use an optical power meter and visual fault locator or OTDR for testing, keep connectors clean with proper cleaning tools, avoid kinks and maintain minimum bend radius, and have terminations performed or verified by trained technicians if precise loss budgets are required

Pre-terminated cables provide predictable loss and faster deployment for known lengths and connector types, while field termination offers flexibility for custom lengths or difficult runs but requires specialized tools and skilled technicians to meet loss specifications
