What is 50/125 Um Multimode Fiber Optic Cable?

The 50/125 um multimode fiber optic cable is a glass-based optical waveguide featuring a 50-micron light-carrying core and a 125-micron cladding layer, manufactured in compliance with ITU-T G.651.1 and ISO/IEC 11801 international standards. Available in OM2, OM3, and OM4 grades, this multimode fiber supports high-bandwidth applications over distances up to 550 meters at 10 Gbps, making it ideal for intra-building and campus-level network deployments.

50/125 Um Multimode Fiber Optic Cable Manufacturing and Production Process

Production of 50/125 multimode fiber optic cable begins with precision preform fabrication using Modified Chemical Vapor Deposition (MCVD) or Outside Vapor Deposition (OVD) processes in ISO Class 1000 cleanroom environments. The fiber drawing tower maintains strict diameter tolerances within ±1 micron, followed by UV-cured acrylate coating application. Each cable assembly undergoes 100% attenuation and bandwidth testing per IEC 60793-2-10, with full RoHS, REACH, and UL compliance certification.

50/125 Um Multimode Fiber Optic Cable Technical Specifications

Core/Cladding Diameter: 50/125 ±1 μm. Numerical Aperture: 0.200 ±0.015 (OM3/OM4). Attenuation: ≤3.0 dB/km at 850 nm, ≤1.0 dB/km at 1300 nm. Minimum Overfilled Launch Bandwidth: 500 MHz·km (OM2), 1500 MHz·km (OM3), 3500 MHz·km (OM4). Effective Modal Bandwidth (EMB): ≥2000 MHz·km (OM3), ≥4700 MHz·km (OM4). Operating Temperature: -20°C to +70°C. Maximum Tensile Load: 600 N (during installation).

Initial coating issue on small portion of batch — supplier resolved promptly

Ordered 5,000 meters of OM3 50/125 multimode fiber for a hospital data center project in Boston. About 400 meters from one spool showed minor UV-cured acrylate coating irregularity that our technicians flagged during installation prep. We contacted the supplier immediately — they responded within 6 hours, issued a replacement spool within 10 days, and provided a written QC report explaining the root cause. Remaining 4,600 meters performed to full IEC 60793-2-10 spec. The after-sales response was genuinely good. Upgraded from initial concern; will give them another chance on next project.

Competitive pricing for OM2 bulk order — delivery slightly delayed but resolved

Sourced 20,000 meters of OM2 50/125 um multimode fiber for a commercial tower structured cabling project in Dubai. Fiber met ISO/IEC 11801 Class OM2 requirements — bandwidth at 500 MHz·km confirmed in our lab. Pricing was 15–20% below regional market rates for equivalent spec product. Shipment arrived 4 days later than the initial estimate due to a transit delay in transit hub, but the logistics team proactively communicated updates and expedited final leg delivery. CE and RoHS certificates were complete. Would rate 5 stars if delivery timeline reliability improves.

Good value OM3 fiber for FTTH aggregation — minor labeling inconsistency

Ordered 12,000 meters of OM3 50/125 multimode cable for FTTH aggregation nodes across three sites in Queensland. Fiber performance was solid — bandwidth confirmed at 1500 MHz·km OFL, attenuation within spec at both 850 nm and 1300 nm. Price per meter was competitive versus local distributors by roughly 18%. Only minor issue: spool length labeling on two reels was off by about 15 meters, which caused minor planning adjustments. Not a major problem but worth noting for precision project planning. Overall strong value proposition; would order again with a clarification request on spool tolerances.
