OM4 LC to LC 50m (165ft) Fiber Patch Cable - HighSpeed 40G/100G

In this review of the OM4 LC to LC 50m (165ft) fiber patch cable, the bottom line is simple: this cable is aimed at network engineers and data center technicians who need reliable multimode links for 10G, 40G, and short 100G runs. The reviewer found the cable delivers predictable performance thanks to its OM4 50/125m multimode construction and LSZH jacket, and it is especially useful where space and duct routing matter. If you need a duplex LC-LC patch cord rated for modern shortreach Ethernet transceivers, this cable is worth considering.

Key Features

• OM4 multimode core: 50/125m fiber construction gives higher modal bandwidth for extended 10G and 40G reach compared with older multimode grades.
• Duplex LC to LC connectors: Small form factor LC ends enable high density patching in racks and panels and plug directly into common SFP+ and QSFP+ transceivers.
• LSZH jacket: Low smoke zero halogen outer jacket reduces toxic emissions in confined telecom rooms and improves safety in enclosed spaces.
• Performance specs: 4700 MHzkm @850nm bandwidth and recommended reaches for 10G/40G/100G give predictability for link planning in enterprise environments.
• Low insertion and return loss: Typical insertion loss around 0.3dB and return loss near 30dB help maintain stable signal integrity across connections.

Who It's For

The cable is best for IT teams, data center operators, and integrators who deploy 10G SR, 40G BIDI SR or shortreach 100G connections and need a tidy LC duplex solution for patch panels and transceivers. It is also suitable for upgrading multimode runs where higher OM4 bandwidth is required without reterminating trunk fibers.

Those who should look elsewhere include users requiring singlemode longhaul links, outdoor rated armored cables, or specialty connector types other than LC. For simple consumer use at very short distances, cheaper generic patch cords may suffice.

Pros & Cons

Pros

• High OM4 bandwidth supports longer 10G and 40G runs compared with OM3 and older multimode cables.
• Compact LC duplex connectors save panel space and are compatible with common SFP+ and QSFP+ modules.
• LSZH jacket improves safety in enclosed installations and is easier to route through existing ducts.

Cons

• Not intended for singlemode or longdistance links, so it is limited to shortreach multimode applications.
• Fixed length may require planning to avoid excess slack in very dense racks.

Specifications

Our Verdict

The OM4 50m LC to LC patch cable is a practical choice for enterprise and data center professionals who need consistent shortreach multimode performance and a compact form factor. With solid insertion and return loss figures, LSZH safety benefits, and compatibility with 10G and 40G optics, it represents good value for standard multimode patching tasks where singlemode or outdoor features are not required.

Frequently Asked Questions

Can this cable be used for 40G connections?
Yes, OM4 multimode is the preferred specification for many 40G shortreach transceivers and the cable supports the recommended distance for 40G at 850nm.

Will it work with SFP+ and QSFP+ modules?
Yes, the duplex LC connectors are compatible with common 10G SFP+ and QSFP+ transceivers that accept LC multimode patch cords.

Is the jacket suitable for indoor use in racks and ducts?
Yes, the LSZH jacket is designed for indoor telecom rooms and ducts where reduced smoke and halogen content are required.
