LC-SC OM1 Fiber Patch Cable 40M - High-Speed Multimode

In this review of the LC-SC OM1 Fiber Patch Cable 40M, the bottom line is clear: this cable is aimed at network engineers and IT teams who need a reliable, short-range multimode link with low insertion loss. The reviewer found the Corning OM1 glass core and ceramic ferrules deliver predictable performance for patching in racks and telecom closets, and the reinforced 2.0mm zip-cord jacket makes handling and routing straightforward during installation. For environments that need dependable 10Gb short-range connectivity without specialty fiber, this cable performs as expected.

Key Features

• Corning OM1 core: The genuine 62.5/125um glass provides consistent multimode performance and predictable modal bandwidth for short-range Ethernet links.
• LC to SC termination: Precision 1.25mm LC and 2.5mm SC ceramic ferrules keep connector loss low so signal integrity is preserved across patch panels and equipment ports.
• Supports multiple Ethernet speeds: Rated for 1Gb, 10Gb, 40Gb and short-range 100Gb links at appropriate distances, making it versatile for mixed-speed racks and telecom rooms.
• Reinforced zip-cord jacket: The 2.0mm OFNR PVC jacket is flexible and resistant to kinking, simplifying routing in tight cable management runs.
• Low connector loss: Typical insertion loss around 0.30 dB and max 0.50 dB help maintain link margin for short multimode runs.

Who It's For

This cable suits data center technicians, enterprise network operators, and telecom staff who need an affordable, tested multimode jumper for patch panels, switches, and SFP transceivers. The 40m length fits intermediate rack-to-rack runs and longer horizontal paths inside larger rooms.

It is not intended for long-haul singlemode links or for installations that require bend-insensitive or armored outdoor cable. Buyers needing extended reach beyond multimode limits or specialized jacket ratings should consider alternate fiber types.

Pros & Cons

Pros

• High-quality Corning OM1 glass and ceramic ferrules deliver reliable, low-loss connections for short-range links.
