Description

Intended for Multidrop Self-Healing Ring topologies, the TC3720 Ethernet Fiber Optic Switch interconnects up to six 10/100M devices at each drop. The ring can consist of either multimode or single mode fibers or CAT5 UTP cables. Fault recovery time is less than 250 milliseconds.

The TC3720 offers a sophisticated Self-Healing Ring scheme. Fault conditions are detected on both Tx and Rx, upstream and downstream of each unit, and automatically re-routed to maintain Ring integrity. If both upstream and downstream fiber breaks, the Point-to-Point Protocol (PPP) can be used over the TC3720 optional internal V.90 modems to provide IP connectivity to a Server/Router through Public Switched Telephone Network.

A Web-based configuration user interface is provided to view and change network settings such as IP Address, Subnet, Gateway, Speed, Half/Full Duplex, Name, Password and other parameters. It also monitors the fiber ring status, alarm conditions, fault locations for local and remote units. The TC3720 can also be configured through a serial console (Out-of-Band).

The TC3720s store-forward switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol. This improves predictable response times under heavy network loads.

The TC3720 offers two multimode (1300nm) or single mode (1300/1550nm) ports and six independent Ethernet 10/100-Base Auto-Sensing switched ports. There are two optional versions (Model TC3720T) for extreme temperature applications  (-20 to 70C, -40 to 80C).

Power is 12VDC, optional 24Vdc, -48Vdc, 125Vdc or 115/230VAC. Power redundancy is standard on 12Vdc. The unit is 19" rack mountable. Optical connectors can be ST, FC or SC.

Typical Application (Application Questions)

The TC3720 is frequently used to interconnect Remote Terminal Units (RTUs) or Programmable Logic Controllers (PLCs) in Utility substation SCADA Networks that require multiple channels and the reliability of a Self-healing Ring Topology. It is also used for similar connectivity applications in Traffic Control, Industrial Process Control and Security System Networks.
