This StarTech.com 3m (9.8ft) LC to LC (UPC) OM5 Multimode Fiber Optic Cable, 50/125µm Duplex LOMMF Zipcord, VCSEL, 40G/100G, LSZH Fiber Jumper Cord is engineered for high-speed data centres. It supports Shortwave Wavelength Division Multiplexing (SWDM) for 40G and 100G networks. The LSZH jacket ensures safer installation in confined spaces. This cable connects LC-equipped network hardware over a 3-metre run.

Slim Specs Table

Engineered for SWDM and 40G/100G Networks

This OM5 duplex cable supports SWDM across 850–953 nm wavelengths. It enables higher bandwidth over fewer strands. Because it is Laser-Optimized Multi-Mode Fibre (LOMMF), it minimises insertion loss. You can deploy it for 40G and 100G Ethernet links.

The UPC polish improves return loss. So signal integrity remains stable in high-density racks. This design suits VCSEL sources used in modern transceivers.

Backward Compatibility with OM4 and OM3

This multimode 50/125µm patch cord is backward compatible with OM4 and OM3 networks. It works with existing 10G infrastructure. However, you must verify transceiver compatibility for your specific hardware. This ensures reliable connectivity in mixed environments.

The LC connectors suit standard SFP and QSFP ports. Always check your device documentation before purchase.

LSZH Safety for UK Installations

The cable features a Low Smoke Zero Halogen jacket. It emits minimal smoke and toxic fumes if exposed to extreme heat. This is critical for trains, aircraft, and industrial settings. It also meets residential building code requirements in the UK.

Because safety standards vary, confirm local compliance for your installation site. The green jacket aids visual identification in cable trays.

Precision Engineering and Reliability

Precision ceramic ferrules ensure correct fibre alignment. This reduces insertion loss and prevents connection issues. The cable is tested to meet or exceed TIA/EIA-568 standards.

It operates from -20°C to 60°C. Storage temperature range is the same. The bending radius is 6 cm, so avoid tight loops during installation.

Optimal Performance with VCSEL Sources

This LOMMF OM5 cable is ideal for 850–953 nm VCSEL and 1300 nm LED sources. It supports extended wavelengths for SWDM applications. This enhances signal quality over OM4 cables.

The duplex design allows full-duplex communication. So data flows bidirectionally without interference.
