Fibre optic cable CUC Exertis Connect 392821

The CUC Exertis Connect 392821 is a 1 m OM4 fibre optic cable with SC and ST connectors designed for high-speed network links. Featuring a 50 µm core diameter and duplex configuration, this multimode cable supports fast data transmission and reliable signal integrity for data centre and enterprise environments. The construction and OM4 grade ensure lower attenuation and improved modal bandwidth compared with lower-grade multimode fibres, making it suitable for short- to medium-reach links where high throughput is required.

Advantages

This OM4 fibre offers predictable performance for multimode systems, providing higher bandwidth and lower loss per metre than OM2 and OM3 in equivalent conditions. The SC and ST connector combination allows compatibility with a wide range of networking equipment and patch panels. At 1 metre length the cable is compact and easy to route inside racks and enclosures, enabling tidy installations and short patch connections with minimal excess slack.

Suitable for

• Short-range multimode connections within data centres and server rooms
• Patch panel to switch or transceiver links in enterprise networks
• High-speed LAN backbones and storage area network (SAN) interconnects
• Optical test setups and lab environments requiring OM4 performance

Key specifications

• Fibre type: Multimode OM4
• Core diameter: 50 µm
• Connector types: SC (one end) and ST (other end)
• Configuration: Full duplex (duplex multimode)
• Length: 1 metre
• Typical applications: Short- to medium-reach high-speed links

How to use

Connect the SC and ST connectors to the corresponding ports on your networking devices, transceivers or patch panels, ensuring the connectors are clean and free from dust before insertion. Align each connector with the device port and insert gently until it clicks or seats firmly; avoid forcing connectors to prevent endface damage. For duplex operation, ensure both fibres are correctly oriented to maintain transmit/receive pair continuity. Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer-recommended minimum bend radius for multimode fibre to preserve optical performance.

Usage recommendations

Inspect and clean connector endfaces with appropriate fibre cleaning tools before each use. Store unused cables in a protective bag or reel to prevent contamination and mechanical damage. For critical links, verify signal integrity with an optical power meter or appropriate diagnostics after installation.
