Applications
The
TC3820 is frequently used to interconnect Remote Programmable Logic
Controllers (PLCs) in high bandwidth applications, such as
interconnecting traffic control video cameras, that require multiple
channels and the reliability of a Self-healing Ring Topology.

Description
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 38 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 (substation hardened) and Traffic Control
environmental and temperature specifications (-40°C to 80°C). It
complies with IEC 61850 & IEEE 1613 standards.
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.
