Indoor OM3 multimode fiber optic cable

Indoor OM3 multimode fiber optic cables are 50/125 µm laser-optimized fibers designed for high-speed 10G Ethernet and indoor backbone applications, available in plenum or riser-rated versions.OverviewOM3 fiber is a 50-micron multimode fiber optimized for laser-based equipment, supporting 10 Gbit/s Ethernet over distances up to 300 meters at 850 nm. It is commonly used in data centers, enterprise backbones, and campus networks where high bandwidth and low latency are required. OM3 fibers are tight-buffered, making them easier to terminate and suitable for indoor installations without additional fan-out kits .Key FeaturesFiber Type: Multimode OM3, 50/125 µm, Corning ClearCurve or equivalent .Bandwidth: 2000 MHz·km at 850 nm, supporting high-speed data transmission .Attenuation: Maximum 3.0 dB/km at 850 nm and 1.0 dB/km at 1300 nm .Strand Counts: Available in 2, 6, 12, 24, and 48 strands for flexible deployment .Jacket Ratings: Plenum (OFNP) or riser (OFNR), flame-retardant, low-smoke PVC or FEP for safety in indoor spaces .Strength Members: Aramid yarn for tensile strength and durability during installation .Tight Buffer Diameter: 900 µm for easy handling and termination .Bend Radius: Minimum 7.2 cm during installation and 4.8 cm during operation for 6-strand cables .ApplicationsIndoor OM3 multimode fiber is ideal for:Data Centers & Server Farms: High-density interconnections between servers, switches, and storage devices .Enterprise & Campus Networks: Multi-floor or multi-building backbone cabling .Telecom & Backhaul Networks: Short-range high-speed links within buildings .High-Resolution Video & Media Centers: Supports 4K/8K video transmission .Healthcare & Research Facilities: Real-time transmission of large datasets like MRI or genomic data .Installation ConsiderationsIndoor Use: Tight-buffered design allows direct termination to equipment.Plenum Spaces: OFNP-rated jackets meet NFPA 262 standards for low smoke and flame resistance .Riser Spaces: OFNR-rated cables suitable for vertical runs between floors.Custom Lengths: Many suppliers offer cut-to-length options and pre-installed pulling eyes for easier installation .Indoor/Outdoor Options: Some OM3 cables are rated for both indoor and outdoor use, with UV-resistant jackets and water-blocking features .SummaryIndoor OM3 multimode fiber optic cables provide high-bandwidth, low-latency connectivity for modern enterprise and data center networks. They are available in multiple strand counts, plenum or riser ratings, and tight-buffered designs for easy installation and termination. With support for 10G Ethernet and beyond, OM3 cables are a reliable choice for short- to medium-range indoor backbone and interconnect applications .
