Tech Supply carries a complete line of TC Comm fiber optic modems, gigabit switches, singlemode to multimode converters, emergency phones, oil refinery switches, traffic control switches, train control switches, fiber optic telephone extenders ranging
from simple "quick talk" extenders to multi-line (24 channel) PBX line
extenders allowing you to use existing fiber optic cable to run your voice needs
over 2 fiber strands or install fiber optic cable one time and use fiber optics
for security proof voice, data, IP, video services on one media- fiber
Multi-Drop Fiber Multiplexer w/Virtual Channel Mapping
Featuring Virtual Channel Mapping, the TC2850 Serial Data Multi-Drop Fiber Multiplexer enables concurrent applications, cost-saving benefits & reduced polling time.
Features
- Virtual Channel Mapping (VCM) Enables Concurrent Applications, Cost-Saving Benefits & Reduces Polling Time
- Sophisticated Self-Healing Ring
- All Digital Design
- Hardened Temperature version exceeds NEMA & CALTRANS specs
- Protocol Transparent
- RS-232, RS-422, RS-485 (2/4-wire)
- Data rates up to 120 Kbps
- Multimode (1300nm) or Single Mode (1300/1550nm)
- Built-In Power Redundancy
- Optical Loop Integrity Test
- Local Dry Contact Alarm Relay
- Rackmount or Standalone
Applications
Because the TC2850 effectively
enables two independent communications
networks in one self-healing
ring topology, it can be used to run
multiple applications concurrently.
For example, it enables virtual pointto-
point configurations, such as a
dedicated telephone circuit, within a
Self-Healing Ring network (See diagram
on back page).
It is also used in larger networks, with
multiple port SCADA Host Controllers,
to speed up polling times. Typical
application environments include
SCADA, Traffic Control, Process
Control, Security, Oil & Gas, and
Energy Management.
