The RLH Fiber Optic Alarm Card has been newly updated to allow monitoring AC Power Supplies in addition to monitoring of DC power sources. This system is a great way to monitor power sources while maintaining complete high voltage isolation.

This new system provides a method of remotely monitoring an RLH 120VAC powered battery backed High Density or Low Density DC power supply, and transmitting normal and alarm status through a single strand of fiber optic cable.

The system requires an RLH Alarm Transmit Card, and an RLH Alarm Receive card. The Transmit Card is connected directly to the AC and DC power source to be monitored. The Alarm Receive Card is located at the opposite end of the fiber optic cable and is locally powered. Upon loss of power, the alarm terminals will open and LEDs display the status of the power supplies being monitored.

The DC PWR INPUT on both Alarm Cards is not polarity sensitive, and the system will operate up to 2 miles over multimode fiber and up to 6 miles over single mode fiber. The RLH Fiber Alarm system card are the standard RLH Fiber Optic Link form factor, and are designed to easily and conveniently fit into the wide array of housings and enclosures RLH industries supplies.

For additional features and information, please refer to the RLH AC DC Fiber Optic Power Monitor and Alarm System Data Sheet.

Fiber optics is the most reliable and safest method of transmitting data or voice services verses all other known copper or radio transmission methods. Now the RLH research and design team has engineered a method for transporting power over fiber optic cable thanks to the advent of our new RLH POF System.

These new systems promise to be widely used by Telephone, Power and Wireless companies that are interested in providing only the best high voltage isolation for copper Telco lines entering high voltage areas.

The RLH DS3 Fiber Converter T3/E3 is a member of the modular RLH Fiber Optic System family and is currently available in any quantity. It converts standard T3 (44.736Mbps) or E3 (34.368Mbps) coax to fiber conversion, and can be used by telco service providers and enterprise level users to connect to communication devices such as Utility, Wireless, PBX, Multiplexers, Routers and video servers via fiber optic cable.

The T3/E3 system operates n pairs extending distances over fiber, improving noise immunity and quality of service while improving intrusion protection, high voltage communications protection and network security.

Being framing independent, the T3/E3 operates with framed or unframed data. It also operates with channelized or fractional unchannelized data streams. It supports B3ZS line coding for T3 (DS3) and HDB3 for E3. RLH DS3 Fiber Converter T3/E3 models are available with multimode, single-mode, and single-fiber (single-mode) options. ST, SC, LC and MT-RJ fiber connector types are supported. Distances of up to 120km for single-mode dual-fiber, 40km for single-mode single-fiber and 5km for multimode fiber are supported.

The T3/E3 supports standard RG-59, 75 ohm coax cabling. Line build-out is user selectable accommodating short-haul distances under 225ft. (68.5m) and long-haul distances up to 1245ft. (380m) for T3 (DS3) and 1445ft. (440m) for E3.

Individual coax and fiber port access can be controlled, providing the network administrator with an easy mechanism for controlling usage and access to the network. The RLH DS3 Fiber Converter T3/E3 features extensive local and remote loop back user-selectable diagnostic modes. Local loop-backs facilitate individual coax or fiber loop back operations. Remote loop back facilitates setting a remote T3/E3 converter to “Slave” loop back mode, in order to test the integrity of the fiber and the remote converter.

Additional diagnostic features include forcing of all 1’s data patterns (AIS) to the coax or fiber interfaces and generating and monitoring a Pseudo Random Bit Sequence (PRBS) per ITU O.151 specification. These diagnostic features combined with the informative and easy to read LED display facilitate quick installation, fault detection, isolation and correction.

The RLH DS3 Fiber Converter T3/E3 modules are compatible in all RLH fiber housings, rack-mountable chassis (19-inch or 23-inch), including the RLH Slim Line single rack space card housings, with any combination of practically all AC or DC 24VDC or 48VDC power supplies. Card can also be used in 1, 2, 3, 4, 6, 7 or 10, 11-card Shelf arraignments which permit high density installations. RLH DS3 system fiber cards are hardened for extreme weather environments.
