Om4 tail fiber

OM4 tail fibers are high-performance 50/125 µm multimode fiber pigtails designed for high-speed data networks, offering low insertion loss, low back reflection, and compliance with international standards.Overview of OM4 FiberOM4 is a multimode fiber (MMF) standard with a 50 µm core and 125 µm cladding, optimized for high-speed short-range applications such as 10G, 25G, 40G, and 100G Ethernet. Compared to OM3, OM4 has a higher modal bandwidth of 4700 MHz·km, lower attenuation (3.0 dB/km), and supports longer transmission distances (e.g., 100G Ethernet up to 100 meters) ( ). OM4 fibers are commonly used in data centers, enterprise networks, and telecommunication applications.OM4 Tail Fiber / Pigtail FeaturesOM4 tail fibers, also called pigtails, are short lengths of fiber terminated with a connector on one end, used for fusion or mechanical splicing to optical cables or patch panels ( ). Key features include:Cable Type: 900 µm tight-buffered LSZH (Low Smoke Zero Halogen) for indoor useConnectors: SC, LC, ST, or FC, optimized for low insertion loss and low back reflectionStandards Compliance: IEC, TIA/EIA, Telcordia, and multimode fiber TIA/EIA 492AAAAPerformance: Insertion loss typically ≤0.25 dB, return loss >28 dBOperating Temperature: -20°C to +60°CApplications: Termination of optical networks, patch panels, wall boxes, optical distribution frames (ODFs), and splice cassettesAdvantages of OM4 Tail FibersHigh Data Rate Support: Suitable for 40G/100G networks due to high modal bandwidthReliable Termination: Factory-assembled pigtails ensure consistent quality and low signal lossFlexibility: Can be used for both fusion splicing and mechanical splicingColor Coding: Standardized aqua jacket for easy identification in multimode networksUse CasesOM4 tail fibers are widely used in data centers and enterprise networks where high-speed, short-distance connections are required. They are ideal for connecting switches, servers, and patch panels, and for upgrading existing OM3 networks to support higher bandwidth without replacing the entire cabling infrastructure.In summary, OM4 tail fibers provide a reliable, high-performance solution for terminating multimode fiber networks, ensuring low loss, high bandwidth, and compliance with industry standards ( ).
