Best practices for dependable links
Whether you are building a campus backbone, turning up a service-provider access network, or hardening an industrial control environment, SmartFIBER Singlemode 9/125 connectors provide the dependable, standards-based terminations required for efficient installation and long-term performance in low-voltage outdoor and mixed-use environments.
Typical constructions include connectorized singlemode 9/125 assemblies such as simplex or duplex jumpers, pigtails, and pre-terminated trunks using common connector types (e.g., LC or SC) with UPC or APC polishes. Options can include riser or plenum indoor jackets and armored or non-armored builds. Availability may vary by part number—please contact Windy City Wire for current selections. All stock SmartWire cables come standard with SmartWire Glide lubrication to reduce pull friction by up to 70%.
OM1 is a multimode fiber with a larger core (typically 62.5/125 μm) designed for shorter-distance, lower-bandwidth applications and legacy LED light sources. OM3 is laser-optimized multimode (50/125 μm) engineered for higher bandwidth and higher-speed links (e.g., 10G and above) over short-to-mid distances, common in modern data centers with VCSEL laser transmitters. OS1 is singlemode fiber (9/125 μm) intended for long-distance, very high-bandwidth links using laser transmitters—ideal for campus backbones, metropolitan, and long-haul runs. In short: OM1 = legacy multimode for short runs; OM3 = high-performance multimode for higher speeds in buildings/data centers; OS1 = singlemode for the longest distances and highest capacity.
