This ST/UPC OM4 multimode fiber patch cable acts as a high‑performance link piece within fiber‑optic networks, bridging optical transceivers and fiber termination enclosures to establish dependable live‑fiber connections. Unlike coaxial cabling fitted with woven shielding layers, data transmission relies entirely on light signals moving through precision‑made glass cores, eliminating risks brought by electromagnetic interference. Built around OM4 laser‑optimized multimode fiber, it adopts a delicate 50μm‑65μm glass core surrounded by low‑refractive‑index glass cladding, which confines light beams inside the core and minimizes optical attenuation. Its violet‑hued outer jacket meets IEC and RoHS regulatory standards. Standard lengths range from 1 m to 4 m. Manufactured complying with global eco‑friendly criteria, this cable assembly delivers stable low‑loss transmission and supports high‑bandwidth 40G/100G Ethernet up to 150 meters.
1.ST/UPC Bayonet Twist‑Lock Connector Resists Vibration‑Triggered Dropouts
Featuring a proven bayonet twist‑locking mechanism, this ST/UPC patch cable maintains firm mating even under constant shaking and physical pulling. It works reliably within industrial‑automation sites and broadcast venues where unexpected link loss cannot be tolerated. With insertion loss ≤0.2 dB and return loss ≥50 dB, it preserves solid signal integrity despite ongoing mechanical strain throughout its service life.
2.OM4 Laser‑Calibrated Multimode Fiber for High‑Speed 40G/100G Links
Constructed with 50μm OM4 multimode fiber, this violet‑jacketed jumper supports 40G and 100G Ethernet at distances reaching 150 meters under 850 nm wavelength, doubling the effective transmission range of OM3 variants. It serves as a preferred cabling option for data‑center backbone trunks, high‑performance computing clusters and enterprise core network infrastructures with heavy bandwidth demands.
3.Violet Color‑Coded Jacket Enables Quick Field‑Level Cable Differentiation
The violet outer sheath complies with TIA‑598‑C global cabling color‑coding specifications for OM4 laser‑optimized multimode fiber. On‑site technicians can instantly tell it apart from orange‑jacketed OM1/OM2 and aqua‑colored OM3 patch cables, lowering mis‑wiring risks during installation and routine maintenance. Tough flame‑retardant jacket material satisfies IEC and RoHS standards for reliable indoor deployment.
4.Multiple Standard and Custom Lengths for Optimized Cabinet Cabling
Ready‑to‑ship standard sizes cover 1 m, 2 m, 3 m and 4 m. This OM4 ST/UPC patch jumper avoids surplus cable loops for clean, organized cable routing. Custom‑tailored lengths are available to match unique rack configurations. Appropriately sized cabling cuts down cable congestion and improves internal air circulation inside densely‑populated equipment rooms.
5.Eco‑Conscious Manufacturing Supports Green‑Focused Network Projects
Produced under rigorous environmental‑protection protocols, this fiber patch cable contains zero lead, mercury, cadmium or other hazardous substances. This non‑toxic cabling choice fits sustainable network‑infrastructure builds, while sustaining excellent optical parameters and long‑term operational stability.
