Moog Protokraft Viking series 4+2 port Copper + Fiber Ethernet switches consist of 4x 10/100/1000Base-T ports with autonegotiation and auto MDI / MDIX circuitry plus 2x 100Base-FX or 1000Base-SX ports in a wall or floor mounted inline MIL-DTL-38999 connector assembly.

The Viking series 4+2 port Copper+Fiber Ethernet switch consists of two Ethernet interfaces for inline port cable consolidation applications. The Copper interface of the Viking series 4+2 port Copper + Fiber switches is a D38999 size 19-35 connector with 4x IEEE-802.3U:2005 compliant 10/100/1000Base-T Ethernet ports plus the 28 VDC power supply input pins. The fiber optic interface of the Viking series 4+2 port Copper + Fiber Ethernet switch is a D38999 size 19-11 connector with 2x 100Base-FX or 1000Base-SX fiber optic Ethernet ports. Designed to operate in harsh environments, these 4+2 port Fiber + Copper Ethernet switches feature excellent thermal characteristics, high tolerance to vibration and shock and corrosion resistant housings operated with 28V power supply. Standard case operating temperature range is -40°C to +85°C, with a standard storage temperature range of -55°C to +100°C. They operate from +28 VDC power supplies.
