LINKOH LK9012P8C4F Industrial Switch is an unmanaged Gigabit Ethernet Switch that features

8-Port Gigabit RJ45 + 4-Port Gigabit SFP optical port, which is equipped with an IP40-rated rugged case for stable operation in heavy industrial demanding environments. Being able to operate under the temperature ranging from -40℃ to +75℃. It provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curbside traffic control cabinets.
