4-Core LC to LC Single-Mode Armored Fiber Patch Cable on Reel

A Four-Fiber LC Connection for Deployable Single-Mode Links

The HHD Fiber 4-core single-mode armored fiber patch cord is a factory-terminated LC-to-LC cable assembly supplied on a portable reel. The reference configuration combines G.657.A1 single-mode fiber, a 5.0mm black TPU main cable and flexible spiral stainless-steel armor for temporary AV, broadcast and field network connections.
Each end has 2  two duplex LC/UPC connectors arranged as two duplex pairs.  Cable length, breakout length, connector protection and reel arrangement can be selected for the project.

Ruggedized LC/UPC Fiber Patch Cord Features

Four single-mode fibers in one main cable: Two LC/UPC duplex pairs at each end provide clearly defined connections for compatible single-mode equipment.
Flexible armored fiber optic cable: A 5.0mm black TPU outer jacket and spiral stainless-steel armor add mechanical protection during handling and installation.
Protected breakout ends: Connector housings and dust caps help protect the LC tails during storage and transport. They do not make exposed LC connections waterproof.
Portable reel storage: The carry handle, reel and securing strap keep the main cable and connector tails together for transport, payout and retrieval.
Project-specific termination: Specify the overall length, breakout length, fiber pairing and identification before production.

This assembly may also be described as a 4-fiber armored cable assembly, 4-strand single-mode armored fiber cable or armoured fibre optic patch lead on a reel.

Typical Applications

Live events and AV rental: Temporary single-mode connections between equipment positions fitted with compatible LC optical interfaces.
Broadcast and outside production: Pre-terminated fiber links for production racks, OB support and venue equipment where the fiber and transceivers match.
LED screen systems: Fiber connections for compatible video processors or converters using the specified single-mode LC interface.
Temporary field networks: Reel-mounted links for short-term installations, maintenance and network restoration.
Use protected routing where the cable crosses pedestrian or vehicle routes. This TPU tactical assembly is not a direct-burial cable.
Choosing a 2-Core or 4-Core Fiber Assembly
A two-core cable contains two fibers and can provide one conventional duplex fiber pair. This four-core cable contains four fibers and can provide two such pairs, depending on the equipment and fiber mapping. Additional fibers may also be reserved as spares.
Fiber count does not determine the transmission speed of each link. Select the fiber type, transceivers, connector polish and optical loss budget for the intended system.

For compatible multimode equipment, see our 4-Core OM3 Armored Fiber Patch Cord on Portable Reel.

Setup and Cable Care

1. Position the reel securely and release the protected connector tails. Pay out the main cable without pulling on the LC connectors or breakout legs.
2. Inspect and clean the LC end faces before connection. Match the fiber numbers, duplex pairing and Tx/Rx polarity to the equipment.
3. Maintain the specified bend radius during retrieval. Fit the dust caps, return the connector tails to their protective housings and secure the cable for storage.

Frequently Asked Questions

Does four-core mean four duplex connections?

No. This assembly contains four optical fibers. In a conventional two-fiber transmit/receive arrangement, they form two duplex fiber pairs. Each end has four LC/UPC connectors grouped into two duplex pairs.
Is this single-mode or OM3/OM4 multimode cable?
This page describes the G.657.A1 single-mode version. OM3 and OM4 are multimode fiber types and must be selected to match compatible equipment; they are not interchangeable descriptions of this product.

Is this a quad-fiber armored jumper?

Yes, when “quad-fiber” means a four-fiber cable assembly. The stated termination here is four LC/UPC connectors at each end, arranged as two duplex pairs. Confirm the actual interface rather than relying on the word “quad” alone.

Are the LC connections waterproof?

Standard LC/UPC connections are not sealed outdoor interfaces. The dust caps and protective housings are for connector protection and storage; this page does not assign an IP rating to the complete assembly. Protect connected LC ends in a suitable enclosure where the environment requires it.

Can I order a different cable or breakout length?

Yes. Specify the required overall length, breakout length at each end, quantity and equipment arrangement. The reel is selected to suit cable storage, handling and the required bend radius.
