Belkin Duplex Optic Fiber Cable
The Belkin F2F402LL-01M is a new duplex multimode fiber optic cable built for high-speed network links. It uses OM3-rated 50/125 micron fiber and terminates in two LC UPC male connectors at each end. The 3.28 ft length suits short patch runs between switches, transceivers or patch panels. Every unit is 100% tested and backed by a lifetime limited warranty.
Multimode fiber distance limits
OM3 multimode fiber supports high bandwidth over short distances, typically up to a few hundred metres depending on the transceiver and data rate. Beyond that reach, signal attenuation and modal dispersion require single-mode cable. The 3.28 ft patch length here is well within the comfortable range for OM3, so insertion loss is minimal. Installers must still observe bend-radius limits and keep connectors clean to maintain performance.
OM3 50/125 micron fiber rating
The defining specification is the OM3 laser-optimized 50/125 micron multimode rating, which determines compatibility with 10 GbE, 40 GbE and 100 GbE short-reach optics. If your equipment calls for OM4 or single-mode fiber, this cable will not meet the link budget. Buyers needing longer runs or different connector types such as SC or MTP should select a different cable.

Questions about this item
Which length of this Belkin duplex fibre cable should I choose?
The cable is supplied in a single 3.28 ft length with LC male connectors on both ends, so no alternative lengths are offered for this model.
What does the 50/125 µm rating mean when the cable is installed?
The 50/125 micron core and cladding are OM3 laser-optimised multimode fibre, designed for high-speed data transmission over short distances in network equipment.
What does the LC duplex interface limit in practice?
Each end carries two LC male connectors, providing a duplex link that fits standard LC ports on switches, transceivers and patch panels.
