ACT 30m Singlemode 9/125 OS2 Indoor/Outdoor Cable, 12 Fibers, LC-LC UPC, LSZH Yellow RL4503

Long fiber optic runs between buildings or across harsh indoor/outdoor environments often fail because standard cables cannot handle moisture, temperature swings, or tight bend radii. The ACT RL4503 solves this with a 30-meter, 12-fiber singlemode OS2 cable that is built for both indoor and outdoor use, terminated with LC/UPC connectors on each end. Its yellow LSZH jacket reduces toxic smoke in case of fire, making it suitable for public spaces and industrial sites.

Who is it for

Network installers and IT managers who need a reliable, pre-terminated backbone link for campus networks, factory floors, or between distribution points. It is also a good fit for anyone upgrading to high-speed singlemode links without field-terminating fibers.

Main features

• 12 singlemode fibers (9/125 µm OS2) in one cable for multiple parallel links or future expansion
• LC/UPC connectors on both ends for low insertion loss and easy patching
• Indoor/outdoor rated jacket (LSZH) withstands UV, moisture, and temperature changes
• Low attenuation: <0.4 dB/km at 1310 nm and <0.3 dB/km at 1550 nm
• Return loss >50 dB ensures clean signal for high-speed protocols

Tips

For outdoor installations, protect the connectors with dust caps when not in use and consider using a pull sock or conduit for the first few meters from the building entrance.
