40Gb OM3 Multimode Duplex LC to LC Fiber Cable - 164ft

Our review of this 164ft OM3 multimode LC to LC fiber cable finds it best for network engineers and data center technicians who need reliable 10 Gigabit connectivity with a plenum safety rating. The bottom line: this cable delivers consistent performance with SFP+ transceivers and other VCSEL-based networking gear while offering a tight, flexible zipcord design that simplifies routing in congested SAN cabinets. Installation is straightforward thanks to embossed A/B labeling and removable dust caps, and the OFNP plenum rating makes it a safer choice for in-ceiling or air-handling spaces.

Key Features

• OM3 LOMMF 50/125 fiber: Supports 10 Gigabit and Fibre Channel links and is optimized for VCSEL transceivers, ensuring reliable high-speed connections.
• LC to LC duplex connectors: Small form factor LC connectors with zirconia ferrules provide precise alignment and low insertion loss for SFP+ and Gigabit modules.
• OFNP plenum jacket: Plenum-rated construction meets UL 910 standards for safer installation in air-handling spaces and ceiling runs.
• Bend-insensitive design: Tight 7.5mm bending radius reduces macro-bending loss and makes routing inside crowded cabinets or trays much easier.
• Tight-buffered zipcord: 2.0 x 4.2mm duplex cable with embossed A/B clips and numbered jacket rings speeds identification and troubleshooting.
• Protective features for installation: Removable dust caps and adjustable clips protect fiber ends during installs while allowing individual fiber access.

Who It's For

Network administrators who run 10GbE or Fibre Channel SAN links and need a durable, standards-compliant multimode patch cable will appreciate this OM3 duplex option, particularly in high-density racks where tight bends and many turns are common. The plenum rating is a clear advantage for installations that pass through ceiling plenums or other air-handling spaces.

Those building long-haul singlemode links, requiring specialty connector types, or needing pre-terminated fanouts for direct device terminations should look elsewhere, because this product is strictly a multimode LC to LC patch cable built for short, high-speed network runs and equipment interconnects.

Pros & Cons

Pros

• Reliable performance with SFP+ transceivers and common Ethernet modules, confirmed by users to work well with Cisco and Netgear gear.
• Plenum-rated OFNP jacket adds safety for in-ceiling and air-space installs without sacrificing flexibility.
• Clear A/B labeling and removable dust caps make installation and maintenance faster and less error-prone.
• Bend-insensitive fiber and slim LC boots simplify routing in dense cabinets and reduce risk of signal loss from tight turns.

Cons

• As a multimode OM3 patch cord, it is limited to short-reach multimode applications and is not suitable for long singlemode links.
• Field termination or different connector types require separate adapters or assemblies since this is a fixed LC to LC cable.

Our Verdict

For anyone deploying short-reach 10 Gigabit or Fibre Channel links in racks or data center cabinets, this OM3 LC to LC 164ft cable is a pragmatic choice that balances build quality, safety, and flexibility. Its plenum rating and bend-insensitive design make it especially good value where routing space is tight or air-handling space is involved, though singlemode or custom-terminated needs will require other options.

Frequently Asked Questions

Will this work with SFP+ 10Gb transceivers?
Yes. The OM3 multimode fiber and LC connectors are compatible with VCSEL-based SFP+ transceivers for 10 Gigabit links.

Is the cable safe for ceiling plenum installation?
Yes. The OFNP plenum jacket meets UL 910 standards and is intended for use in air-handling plenums.

Can I use this with Gigabit Ethernet modules?
Yes. OM3 is backward compatible with Gigabit Ethernet standards such as 1000Base-SX and other multimode protocols.
