Siemens 6XV1873-3AH30 SIMATIC NET FO Standard Cable 50/125 4xBFOC 3 m Industrial Network Cable

The Siemens 6XV1873-3AH30 is a 3 m SIMATIC NET FO Standard Cable 50/125, a glass multimode fiber-optic jumper preassembled with four BFOC connectors for 2x2 fiber-optic connections. Rated for indoor and outdoor installation, it carries a maximum attenuation of 2.7 dB/km at 850 nm and supports Industrial Ethernet and PROFIBUS links over glass fiber where electrical isolation or long, EMI-immune runs are needed.

Selection Notes

At 3 m, this jumper is sized for a patch panel to switch or NIC connection inside one cabinet, or between adjacent cabinets, not for a machine-to-machine backbone run. The 50/125 OM2 fiber and 2.7 dB/km attenuation figure leave most of the 5000 m 100BaseFX or 3000 m PROFIBUS distance budget unused at this length, so the choice here is about connector fit (four BFOC ends) and cabinet layout rather than reach. Pick a longer preassembled length when the two ends sit in different cabinets or on different machine bases; a shorter one only adds unnecessary slack.

Applications

Fiber-optic PROFIBUS and Industrial Ethernet backbone links between SIMATIC NET components, and BFOC patch connections on switches or panels where a run crosses drive, welding, or other high-EMI cabling.
