Keyed fiber optic patch cables provides fast and easy connection identifications, they prevent improper connections of separate networks, huihongfiber LC secured connectors work with the corresponding same color LC adapters, available in OS2, OM1, OM2, OM3 types.

Features of Keyed LC fiber optic patch cables

Provides fast and easy network identification
Manage multiple networks w/reduced risks
Prevent improper connection of separate networks w/common access points.
LC secure connectors mate only w/same-color LC adapters
Connector and adapter colors must match, or the keying will prevent them from carrying the signal
Added security: Secured LC Keyed connectors won't even mate with standard LC adapters
Keyed LC connector solution is available in singlemode (OS2), 62.5 um multimode (OM1), standard 50 um (OM2) and laser-optimized 50 um multimode (OM3/OM4)

To choose suitable optical fiber patch cord

The difference of OM4 and OM3 optical fibers:
1. OM4 was developed specifically for VSCEL laser transmission and allows 10gbps rate with distance up to 550 meters (compared to 300 meters with OM3).
2. The effective modal bandwidth for OM4 is more than double of OM3.
3. For OM4 patch cable, it is 4700 MHz.km while for OM3, it is 2000 MHz.km.
