Ideal for mission critical fiber optic ring networks, the TC3820 Redundant Ring Gigabit Ethernet Switch provides maximum reliability through its sophisticated redundant ring technology. If a fiber cable or device failure occurs, the data path automatically switches over within 250 msec. to the secondary path to maintain Ring network integrity.Available with SNMP Management, the Model TC3820 1000Base-SX/LX Switch provides six 10/100M copper ports and two Gigabit fiber ports. It can be daisy-chained and supports distances between switches up to 100 km.

The Ring can be single mode or multimode fiber (1300/1550nm) or CAT5 UTP cables. The TC3820 is IEEE 802.3, 802.3u, 802.3x and 802.z compliant.Industrial Hardened, Rugged or Outdoor versions are available for harsh environments (e.g. Process Control applications in Manufacturing, Utility, SCADA, Transportation, & Traffic Control). These versions exceed all pertinent Utility and Traffic Control environmental and temperature specifications (-40°C to 80°C).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 TC3820 can also be configured through a serial console (Out-of-Band).

The TC3820's store-forward switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol.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

Because it functions like an Ethernet bridge (connects multiple Ethernet segments to prevent unnecessary network traffic), it creates an efficient sub-divided switched LAN that provides full and transparent bandwidth for each segment.

The TC3705's modern switching technology eliminates the congestion problem inherent to the contention-oriented Ethernet CSMA/CD protocol. This improves predictable response times under heavy network loads. Previously, expensive routing technology was used to alleviate congestion from heavy traffic loads.Power is 12VDC, optional 24Vdc, -48Vdc, 125Vdc or 115/230VAC with an external power cube. The TC3705S is the standalone/wallmount unit. The TC3705R rackmount version fits into the TCRM192 or TCRM196 19" rackmount card cages. Optical connectors can be SC, ST or FC.
