The CX82051MSTR-2 Unmanaged Ethernet Switch from Pelco is an unmanaged Ethernet switch that provides (5) 10Base-T/100Base-TX ports and (1) 100Base-FX port that accepts two fibers. This model uses ST fiber connectors over multi-mode fiber and is capable of transmission distances up to 3.7 miles (6km).
Two fibers are required to transport bidirectional data over the fiber port. The fiber port on the switch is forced to full-duplex 100Mbps operation. Networking functions for each of the five 10Base-T/100Base-TX ports (RJ-45 twisted-pair copper ports) are user-selectable by means of a rotary switch. Autonegotiation allows a 10Base-T/100Base-TX port to automatically negotiate between 10Mbps and 100Mbps data rates and between full-duplex and half-duplex modes. If autonegotiation is not desired, a port can be forced to specific modes of operation: 10 Mbps or 100 Mbps data rate, half-duplex or full-duplex mode, and enabling/disabling of flow control.
The auto MDI/MDI-X feature allows each RJ-45 port to connect to either a straight-through or crossover RJ-45 cable. The unit's modular design makes it well suited for standalone or rackmount use. A rackmount kit and other accessories are separately available.
This solution uses ST fiber connectors over multi-mode fiber and is capable of transmission distances up to 3.7 miles (6km)
This model differs from the "FX" version of the product in its conformal coating, which is required for operation in environments with relative humidity above 95% (condensing)
