LWL duplex adapter cable 1st side LC duplex, 2nd side 2xST E9/125 5.0 m. The LC duplex fiber optic patch cables from Telegärtner are suitable for use within structured cabling (ISO/IEC 11801) in environments such as data centers, office buildings, telecommunications rooms, and any other locations where fiber optic patch cables are needed. Among all components of a transmission path, patch cables are subjected to the highest loads and the greatest wear. Therefore, many users rely on patch cables from Telegärtner: optimally coordinated components, the highest quality standards, a thoroughly controlled manufacturing process, and 100% attenuation testing ensure safe and reliable network operation. The patch cables in categories OM3-OM5 (IEC 60793-2-10 Type A1a.2-4, ITU G.651.1) and OS2 (IEC 60793-2-50 Type B1.3, ITU G.657.A1) also feature bend-optimized fibers to enable optimal transmission even in tight spaces.
