Fibre optic cable QOLTEC 54033 3 m SC to LC, 9 µm singlemode, yellow, full duplex

QOLTEC 54033 is a 3 m fibre optic patch cable with an SC connector on one end and an LC connector on the other. The cable uses a 9 µm core singlemode fibre suitable for long-distance or high-speed point-to-point links. The yellow outer jacket denotes singlemode fibre and the full duplex configuration supports simultaneous transmit and receive channels for network equipment, transceivers, switches and fibre patch panels in data centers and telecom installations.

Advantages

The QOLTEC 54033 combines a standard SC connector with a compact LC connector to provide compatibility with a wide range of devices while saving rack space where LC ports are used. Its 9 µm singlemode fibre ensures low attenuation and stable signal transmission over longer distances compared with multimode options. The full duplex wiring enables simultaneous two-way communication, simplifying deployment for network uplinks and transceiver pairs. The yellow jacket and standard connector types make identification and maintenance straightforward in multi-cable environments.

Suitable for

• Interconnecting switches, routers and transceivers in enterprise and data centre racks
• Patch panels and fibre termination panels with SC or LC ports
• Point-to-point singlemode links where compact LC connections are required
• Telecom and carrier optic installations that use full duplex singlemode cabling

Key specifications

• Cable length: 3 m
• Fibre type: Singlemode, 9 µm core diameter
• Connector A: SC (single connector)
• Connector B: LC (single connector)
• Configuration: Full duplex
• Jacket colour: Yellow (singlemode identification)

How to use

Before installation, verify that the connected devices use singlemode ports and that the SC-to-LC connector combination matches the equipment. Route the cable without tight bends and avoid stress near the connector ferrules. Insert the SC connector into the SC adapter or port until it clicks and align the LC connector with the LC port, pressing gently until it latches. For full duplex links, ensure transmit and receive channels are crossed or aligned according to the device port labelling to establish correct signal flow.

Usage recommendations

Handle connectors by the boot and housing to avoid touching ferrules. Use dust caps when connectors are not in use and clean fibre endfaces with approved fiber cleaning tools prior to mating. Maintain bend radius greater than the manufacturer’s minimum and secure the cable to prevent strain on connectors in racks and panels.
