D9100EWDM Series- Point-To-Point/Line Terminating RS-232 Data Transceiver, Single Fiber Operation: This fiber optic data transceiver transmits and receives full duplex RS-232 data over one multimode or single mode optical fiber, and may be linked for use in point-to-point, point-to-multipoint, or star network architectures. Provides for transmission distances of up to 46 miles without requiring any manual adjustments. Optical attenuators are never required, even when using very short run lengths of fiber with minimal insertion loss. The D9100EWDM series is ideal for use in traffic signalization networks where the fiber count may be limited.

D9100WDM Series - RS-232 Multi-Drop Transceiver, Single Fiber Operation: This fiber optic data transceiver provides full duplex RS-232 multi-drop (drop and repeat) communications in poll and respond master/local network topologies over one multimode or single mode optical fiber. Transmission distances of up to 46 miles between transceiver units may be accommodated without requiring manual adjustments or optical attenuators. Optional battery back-up provides for uninterrupted data communications in the event of a loss of prime 115/230 VAC operating power. The D9100WDM series is ideal for use in traffic signalization networks where the fiber count may be limited.


D1200 Series -T1/E1 (CCITT) Transceivers provide T1 or E1 fiber optic point-to-point data transmission over multimode or single mode fiber optic cable.

D9100E Series- Point-To-Point/Line Terminating RS-232 Data Transceiver: This fiber optic data transceiver transmits and receives full duplex RS-232 data, and may be linked for use in point-to-point, point-to-multipoint, or star network architectures. Provides for transmission distances of up to 42 miles (69 km) without requiring any manual adjustments. Optical attenuators are never required, even when using very short run lengths of fiber with minimal insertion loss. Available in one or two fiber variants, the one fiber device is product series D9100EWDM and is ideal for use in traffic signalization networks where the fiber count may be limited.

D9100 Series - RS-232 Multi-Drop Transceiver: This fiber optic data transceiver provides full duplex RS-232 multi-drop (drop and repeat) communications in poll and respond master/local network topologies. Transmission distances of up to 42 miles (69 km) between transceiver units may be accommodated without requiring manual adjustments or optical attenuators. Available in one or two fiber variants. Optional battery back-up provides for uninterrupted data communications in the event of a loss of prime 115/230 VAC operating power. Available in one or two fiber variants, the one fiber device is product series D9100WDM and is ideal for use in traffic signalization networks where the fiber count may be limited.

D19100SHR Series - RS-232, RS-422 or RS-485 Fault-Tolerant, Self-healing Ring Transceiver: Provides user-selectable mixed RS-232, RS-422, or RS-485 true fault-tolerant, multi-drop data transmission over multimode or single mode optical cable. Multiple/floating master operation significantly enhances the reliability of the network by virtually eliminating the possibility of a single point of failure. Provides for transmission distances of up to 37 miles (60 km) without requiring any manual adjustments. Optical attenuators are never required, even when using very short run lengths of fiber with minimal insertion loss. This unit requires only two optical fibers to provide full duplex communications.

D9200 Series-Point-to-Point RS-232 Transceiver Unit with Handshake, optically transmits the full complement of control/handshaking signals for those systems where software and/or hardware considerations require live handshake capability. Available in one or two fiber variants, the one fiber device is ideal for traffic signalization networks where the fiber count may be limited.
