The BLACK BOX LBH120A-H-20K-SC is a hardened mini industrial Ethernet switch designed for harsh environments where space and reliability are critical. With one single-mode SC fiber port and four 10-/100-Mbps RJ45 ports, it enables unmanaged switching between multiple traffic segments in factories, power plants, mining operations, and military sites. Compact, rugged, and DIN rail mountable, it operates in temperatures from -13 to 140º F (-25 to 60º C) and supports long-distance fiber connections up to 20 km, making it ideal for industrial networking, FTTH, and transportation applications.
