StarTech.com 1m LC to LC OM5 Duplex Fiber Optic Cable, 50/125µm LSZH

StarTech.com 1m OM5 LC to LC Duplex Fiber Cable | LSZH LOMMF

The StarTech.com 1m (3.3ft) LC to LC (UPC) OM5 Multimode Fiber Optic Cable, 50/125µm Duplex LOMMF Zipcord, VCSEL, 40G/100G, LSZH Fiber Jumper Cord is designed for high-speed SWDM applications. It supports 40G and 100G connectivity over short distances. This cable is ideal for modern UK data centres requiring reliable multimode performance. Its LSZH jacket adds safety for indoor installations.

Key Technical Metrics

SWDM Support for 40G/100G Networks

This OM5 cable supports Shortwave Wavelength Division Multiplexing (SWDM). It operates across 850-953 nm VCSEL wavelengths. This allows four lanes of data over a single duplex pair. You can achieve 40G and 100G speeds without upgrading to single-mode fibre. It is a cost-effective upgrade for existing multimode infrastructure.

Engineered for Low Insertion Loss

Precision ceramic ferrules ensure accurate core alignment. This minimises insertion loss and prevents signal degradation. The UPC polish improves return loss compared to older PC standards. Because the cable is Laser-Optimized Multi-Mode (LOMMF), it performs reliably with VCSEL sources. This guarantees stable connectivity in high-density racks.

Backward Compatibility with OM4/OM3

This OM5 patch cord is fully backward compatible with OM4 and OM3 networks. You can use it in legacy 10G environments without issue. It ensures a seamless transition as you scale bandwidth. However, you must verify that your existing patch panels support LC connections. This cable does not change your current network topology.

LSZH Safety for UK Installations

The LSZH jacket emits minimal smoke and zero halogen when exposed to heat. This is critical for confined spaces like trains, aircraft, or server rooms. It meets UK building code requirements for low-toxicity cabling. Because of this, it is safer for staff during an emergency. Always confirm local fire regulations for your specific installation site.

Robust Mechanical Design

The cable features a 6 cm bending radius. This prevents sharp kinks that can damage the fibre core. The 2.9 mm diameter offers durability while remaining flexible. It operates between -20°C and 60°C. This range covers most UK indoor environments. The green jacket allows for easy identification in complex cable runs.
