Fibre optic cable ROLINE OM4 LC/LC 20m

Fibre optic cable ROLINE OM4 LC/LC 20m is a 20‑metre duplex multimode cable with OM4 (50/125 µm) fibres and LC connectors on both ends. The OM4 fibre and low‑loss connector quality provide very low insertion loss and support high‑bandwidth applications such as 10 Gb/s Ethernet, Fibre Channel and OIF links to extended distances. Material and jacket meet ROLINE quality standards; the cable is supplied in purple.

Advantages

The assembled cable uses low‑loss LC connectors to achieve reduced insertion loss and improved return loss compared with standard connectors, which helps maintain signal integrity over longer runs. OM4 modal bandwidth (4,700 MHz·km) enables support for 40 and 100 Gigabit Ethernet in data centre and campus backbones while keeping installation flexibility and durability expected from ROLINE products.

Suitable for

• Data centre interconnects and server rack uplinks
• Campus backbone links and building risers
• High‑speed Ethernet (40G/100G) and 10 Gb/s Fibre Channel links
• Short to medium‑distance multimode fiber runs up to recommended OM4 distances

How to use

Route the duplex cable between LC‑terminated ports, ensuring LC connectors are aligned and clicked into place in the corresponding transceiver or patch panel ports. Avoid tight bends and maintain the cable’s minimum bend radius during installation. Verify link performance after installation using appropriate test equipment and follow standard multimode fiber handling practices to keep connectors clean and undamaged.

Recommendations

Use the low‑loss LC connections for links where minimizing insertion loss and maximizing return loss are important. For 40G/100G applications verify transceiver and channel specifications for OM4 support and observe recommended OM4 maximum distances for your specific equipment.
