ACT RL4501 10 m Singlemode OS2 9/125 µm Indoor/Outdoor Fiber Optic Cable, 12 Fibers, LC/UPC to LC/UPC, LSZH Yellow

Long-distance, high-bandwidth links in mixed indoor/outdoor environments often fail because ordinary patch cords cannot withstand temperature swings, moisture, or UV exposure. The ACT RL4501 solves this by providing a pre-terminated 12-fiber singlemode OS2 trunk built for both indoor and outdoor use, with LC/UPC connectors on both ends for fast, reliable deployment.

Who is it for

Network installers and IT teams who need a durable, ready-to-pull multi-fiber backbone between buildings, across campuses, or inside large facilities. It is ideal for connecting switches, patch panels, or fiber distribution units where 12 singlemode channels are required.

Main features

• 12 singlemode fibers, 9/125 µm OS2, for long-reach, high-speed transmission.
• Pre-terminated with LC/UPC connectors on both ends, eliminating field splicing.
• Indoor/outdoor rated LSZH yellow jacket: low smoke, zero halogen, UV and moisture resistant.
• 10 meter length, suitable for many cross-connect or backbone runs.
• Low insertion loss (<0.3 dB per connector) and high return loss (>50 dB UPC) for clean signal integrity.

Tips

Use bend-insensitive routing practices: avoid sharp bends and maintain the manufacturer's minimum bend radius to preserve performance. For outdoor transitions, protect connectors with dust caps until mating and use suitable enclosures at building entry points.
