Optical patchcord TB LC-LC OM4 duplex 3m

TB Optical patchcord LC-LC OM4 duplex 3m is a multimode fiber jumper designed for short- to medium-range high-speed links. It features LC connectors on both ends in a duplex configuration and OM4 graded-index multimode fiber to support enhanced bandwidth for 850 nm applications. The 3-meter length makes it suitable for connections inside data centers, telecom closets and network equipment racks where low insertion loss and consistent performance are required.

Advantages

This optical patchcord delivers reliable multimode transmission with low insertion loss and stable mating performance thanks to precision LC connectors. The OM4 fiber improves modal bandwidth compared with lower-grade multimode fibers, enabling higher data rates over the intended distance. The duplex configuration simplifies duplex transceiver hookups and reduces cable clutter in rack environments.

Suitable for

• Interconnecting switches, transceivers and patch panels inside data centers
• Short-run links between network racks and telecom closets
• High-density installations requiring LC duplex connections
• Multimode 10G/40G/100G links over OM4-rated distances

When it may not be suitable

This patchcord is multimode OM4 and intended for short- to medium-range fiber links; it is not suitable for long-haul or singlemode deployments that require singlemode fiber and different connectors. It should not be used where direct outdoor burial, continuous flexing, or exposure to harsh environmental conditions is expected unless protected by additional conduit or housing.

Key specifications

• Fiber type: OM4 multimode
• Configuration: Duplex
• Connector type: LC to LC
• Length: 3 m
• Typical applications: 850 nm multimode transceiver links
• Performance characteristics: low insertion loss, stable mating

How to use

Route the patchcord between ports ensuring bend radii are respected to avoid micro-bending losses. Insert each LC connector into the corresponding LC port until it clicks, matching duplex orientation for transmit/receive alignment. When disconnecting, press the latch on the LC connector and pull straight out. Avoid excessive twisting or tension on the cable during installation and secure excess length with cable management to maintain performance.

What to consider before purchase

• Confirm equipment supports LC duplex connectors and OM4 multimode fiber
• Verify 3 m length is appropriate for rack-to-rack or panel-to-equipment runs
• Assess whether singlemode fiber or outdoor-rated cabling is required instead

Usage recommendations

For best results, use this LC-LC OM4 duplex patchcord in indoor, controlled environments with proper cable management, maintain bend radius, and periodically inspect connector endfaces for contamination. Cleaning connectors before mating helps preserve low insertion loss and reliable links.
