How to Choose the Right OM4 Configuration
Use these quick checks to match the right ST to ST OM4+ cable to your deployment.
Confirm Distance & Bandwidth
OM4 supports strong medium-distance performance for high-speed links. If your run needs longer reach or future long-haul growth, singlemode OS2 may be the better fit.
Select Cable Length
Choose the length that matches your route cleanly so you avoid excess slack and keep the installation organized.
Choose Jacket Type
Use OFNR for standard spaces, OFNP for plenum-rated areas, and LSZH where low-smoke, halogen-free cable is preferred.
Match the Connector Layout
ST on both ends gives you a rugged, secure connection style that works well in network closets, telecom rooms, test setups, and equipment racks.
Advantages Over Previous Fiber Types
