Black Box EFN110-020M-LCLC

Overview

The Black Box EFN110-020M-LCLC is a multimode fiber patch cable designed for reliable short-distance data transmission within data centers, wiring closets, and laboratories. Measuring 65.6 feet (20 meters) in length, it connects devices such as top-of-rack switches, SAN equipment, and patch panels with minimal signal loss. The cable features OM1 fiber and LC connectors on both ends, making it a practical choice for maintaining consistent bandwidth in environments where space and signal integrity are critical.

Key features

• OM1 multimode fiber ensures dependable data transmission over short distances, ideal for internal network connections.
• LC connectors occupy less space than traditional SC connectors, allowing for higher port density on patch panels and switches.
• Ceramic ferrules in the connectors reduce insertion loss to approximately 0.3 dB, preserving signal strength across connections.
• Durable PVC jacket withstands temperatures from –4 to 167°F, suitable for climate-controlled server rooms and areas with occasional temperature changes.
• Bright orange jacket color makes it easy to identify and trace multimode fiber links during maintenance and troubleshooting.

Key specs

• Fiber type: OM1 multimode
• Length: 65.6 feet (20 meters)
• Connector type: LC to LC
• Insertion loss: approximately 0.3 dB
• Jacket material: PVC
• Operating temperature range: –4 to 167°F (–20 to 75°C)

Connectivity and compatibility

This cable is compatible with networking equipment that supports LC multimode fiber connections, including switches, SAN devices, and patch panels. Its LC-to-LC configuration is especially useful in high-density environments where maximizing port availability is important. The OM1 fiber supports standard multimode transmission protocols commonly used in enterprise and data center networks.

Ideal uses and environments

The EFN110-020M-LCLC fits well in data centers, telecommunications closets, and laboratory setups where short-reach fiber connections are needed. It is a strong choice for linking rack-mounted equipment or patching between panels during network upgrades and maintenance. The cable’s temperature tolerance and flexible jacket also make it suitable for locations with varying environmental conditions, such as production floors or campus telecom rooms.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
