Model 4199 allows a Cat 5e device connected to the switch's COMMON connector to access any of four fiber optic networks connected to the A, B, C, or D ports. The Model 4199 automatically remains in the last position when power is lost and returned.

Model 4198 8-Way Fiber Optic Switch Converter with Remote Control accesses any of eight fiber optic network ports, 1-8, from a computer connected to the COMMON 100 Base-TX port. Internal circuitry insures isolation between networks or devices.

Model 7357 Cat5e RJ45 A/B/OFFLINE Switch with 10/100 Base-T LAN Telnet Access allows sharing a device connected to the COMMON port among two other devices connected to A and B ports. Secure off-line position stops all data throughput for the unit.

Model 4502 USB Type-A A/B Switch serves many applications: switches between two USB devices without having to disconnect cables; enables sharing a USB device between 2 PC's; connects a computer to multiple USB devices.

Model 4187 ST Duplex 100BaseFX AB Switch with Remote Port accesses either of two Fiber 100BaseFX ports from a 100BaseFX "COMMON" port. The switch is compliant with 802.3u 100BaseFX standard. Graphical User Interface (GUI) option is offered.

Model 4196 SC Duplex A/B/C/D/OFF-LINE Switch allows a fiber optic device connected to the SC Duplex COMMON connector to access any of four fiber optic networks connected to A, B, C, or D ports or to disconnect completely from all output ports.

The QuickSwitch® 4195 Fiber Optic Switch / Converter allows accessing two separate fiber optic 100 Base FX ports (A and B) from a 100 Base TX Fast Ethernet port (COMMON). The fiber optic / twisted pair copper conversion is built-in!

QuickSwitch® 4193 fiber optic network switch / converter accesses any of eight fiber optic networks from one computer. Simple pushbutton switching eliminates plugging and unplugging patchcords, minimizing connector wear and increasing reliability.

QuickSwitch® 4192 fiber optic network switch allows a fiber optic device connected to the SC duplex COMMON connector to access any of four fiber optic networks connected to the A, B, C or D ports, or to disconnect completely from all output ports.

The QuickSwitch Model 4189 allows accessing any one of four separate fiber optic network ports, 1, 2, 3, or 4 from a computer connected to the COMMON 100Base-TX port. The fiber optic / twisted pair media conversion is built in.
