EFB Elektronik INFRALAN U-DQ(ZN)BH 4G 50/125 OM5 LSZH nero CPR Dca

The EFB Elektronik INFRALAN U-DQ(ZN)BH 4G 50/125 OM5 LSZH Black CPR Dca is a high-performance loose tube fiber optic cable designed for demanding indoor and outdoor installations. With 4 multimode fibers of OM5 class, it supports wideband multimode fiber (WBMMF) technology for high-speed data transmission over short to medium distances. The cable features a low smoke zero halogen (LSZH) jacket, ensuring safety in confined spaces, and meets CPR fire class Dca-s2, d2, a1 for European construction regulations.

Advantages

OM5 fiber enables transmission over multiple wavelengths, increasing capacity without additional fibers. The LSZH jacket reduces toxic and corrosive emissions during fire, making it ideal for public buildings and data centers. The loose tube construction provides excellent protection against moisture and mechanical stress.

Suitable for

• Data center backbone cabling
• Local area network (LAN) installations
• Building and campus backbone networks
• Industrial environments requiring flame-retardant cables
