This ST‑terminated OM4 multimode fibre patch cable functions as a high‑speed optical link for short‑reach high‑bandwidth infrastructure, bridging optical transceivers and termination hardware to establish stable light‑path connections. Unlike shielded coaxial wiring, data transmission relies entirely on light beams travelling through fine‑structured glass cores, free from electromagnetic interference. Built around OM4 multimode fibre, it features hair‑thin 50μm‑65μm core surrounded by low‑refractive‑index glass cladding to constrain light propagation. Its violet‑coloured outer sheath complies with IEC and RoHS regulatory standards. Standard stock lengths cover 1 m‑4 m. Manufactured following eco‑friendly production protocols, this assembly delivers consistent low‑loss performance and supports 40G/100G Ethernet traffic across distances up to 150 metres.
1. OM4 Laser‑Optimised Fibre Handles 40G / 100G High‑Speed Workloads
Constructed with premium OM4 multimode fibre, this ST patch cord delivers enhanced modal bandwidth and reduced attenuation versus OM3 variants. It sustains stable 40G and 100G data throughput up to 150 metres at 850 nm wavelength. It serves as a dependable cabling option for data‑centre inter‑rack links, enterprise‑grade backbone networks and high‑performance computing setups.
2. Robust ST Bayonet‑Lock Connectors Withstand Vibration Interference
Equipped with ST straight‑tip interfaces on both ends, the quarter‑turn bayonet locking structure creates firm mechanical engagement. This design guards against accidental loosening or disconnection, well‑suited for industrial premises and telecommunication sites subject to mechanical shock. High‑precision zirconia ceramic ferrules secure low‑loss transmission and maintain steady performance across repeated mating cycles.
3. Violet LSZH Sheath Combines Fire‑Safety and Eco‑Friendly Properties
The distinctive violet outer casing follows TIA‑598‑C colour‑coding rules for OM4 multimode fibre, enabling instant visual distinction among various cable grades. Made of LSZH low‑smoke‑zero‑halogen compound, it satisfies IEC and RoHS criteria. It minimises emission of poisonous halogen fumes under fire conditions, offering safe deployment inside data‑centres and public‑access buildings.
4. Optimised Glass‑Core Architecture Preserves Signal Quality
High‑purity glass core paired with low‑refractive cladding effectively traps light inside the core area. This structural design curtails signal dissipation during transmission. For multimode applications, it achieves insertion loss ≤0.3 dB and return loss ≥35 dB to sustain stable high‑speed data throughput.
5. Broad Compatibility and Flexible Length Customisation for Rack Deployment
Off‑the‑shelf lengths range from 1 m to 4 m, with custom‑specified sizes available upon request. Properly dimensioned jumpers eliminate surplus cable slack for tidy cable routing. Fully interoperable with standard‑spec ST adapters and patch panels, it fits seamlessly within 40G/100G network infrastructure to interconnect transceivers, termination boxes and patch‑panel hardware.
