Fiber Optical Duplex Cable InLine LC/ST 50/125µm OM3 3m

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 3m is a 3-metre multimode patch cable engineered for high-speed data transmission in local area networks and structured cabling. It combines an LC connector on one end with an ST connector on the other, supports full-duplex operation and uses a 50/125 µm core/cladding diameter matched to OM3 multimode performance. The cable is designed to preserve signal integrity over short- to medium-distance links and to integrate with equipment that requires LC or ST terminations.

Advantages

This OM3 multimode duplex cable provides low attenuation and controlled modal bandwidth suitable for gigabit and 10 Gigabit Ethernet over multimode fibre. The LC and ST connectors offer wide device compatibility: LC for modern transceivers and ST for legacy equipment. The 3 m length balances reach and manageability in racks, patch panels and desktop setups. The cable jacket and connector ferrules are built to sustain repeated insertions and maintain optical alignment.

Suitable for

• Patch connections between switches, routers and transceivers in data centres and telecommunications rooms
• Connecting network equipment that uses LC port to devices with ST interfaces
• Short- to medium-distance multimode fibre links carrying high-speed Ethernet (1G/10G)
• Laboratory test setups and education environments requiring reliable multimode links

How to use

Identify the LC and ST ports on your equipment and ensure both ends are clean before installation. Insert the LC connector into the corresponding LC transceiver or port until it clicks into place. Align and plug the ST connector into the ST receptacle using the bayonet coupling, twisting the connector sleeve to secure it. Route the cable to avoid tight bends and mechanical stress; maintain minimum bend radius recommended for multimode patch cables. Verify link status on connected devices and perform optical power or link diagnostics if necessary.

Usage recommendations

Keep connector endfaces protected with dust caps when not connected and clean with approved fiber cleaning tools before mating. Avoid repeated sharp bends and heavy compression; store the cable coiled gently. For critical links, test insertion loss and return loss after installation to confirm performance meets network requirements.
