The new RLH Analog Current Loop Fiber Optic Link Card is designed to be used as an interface card for industrial process controls such as water flow meters, pressure and temperature sensors.

This new card is perfect for HVP applications, and where superior noise, electrical and RF interference rejection are important. The analog current loop card operates on 4-20mA, 0-10VDC and transmits over fiber optic cable.

RLH Telco Turn-key Units are pre-configured cabinets and pedestals that offer a fast and convenient way to set up a Fiber Optic Link/Telco Demarc system outside the ZOI or at the CFJ.

Systems include an RLH Card Shelf pre-wired to a terminal, terminal test lead, 25 pair gas tube protected terminal and 8 or 14 card NIU Housing. Turn-key units offer rapid and uniform installation at the job site and are ready for fiber and telco plug-in. Telco Turn-key units offer substantial cost savings and have all necessary copper and fiber equipment housings and connection terminals pre-installed and pre-wired.

Turn-key Telco Units can be installed into RLH Type-03/07 pedestals, galvanized steel, aluminum or fiberglass cabinets, and are covered by our lifetime warranty.


At RLH we have always engineered our fiber optic link equipment to meet or exceed industry requirements. Now as more customers are standardizing on the main Bellcore (now Telecordia) Network Equipment-Building System (NEBS) requirements, along with important sister documents for design and operation, our NEBS Level 3 compliance testing is nearly complete. This is the most stringent of the NEBS suite of tests, and we are pleased that the testing process has been uneventful.

This is just another example of the way in which we design, engineer and manufacture our Carrier Class equipment in the USA to meet the highest performance standards.

Because of our commitment to quality and reliability, we are the only manufacturer in the industry today that offers a UNCONDITIONAL LIFE TIME WARRANTY on our fiber optic link products.

RLH Industries, Inc. is a world leader in fiber optic link products and engineering services for the telecommunications industry. Located in Orange, California, USA, RLH Industries has been designing, engineering and manufacturing fiber optic solutions since 1988. RLH is recognized as an innovator in the fiber optics industry, and has pioneered solutions for High Voltage Isolation, PCS and Critical Communications applications.

Our Fiber Optic Link products are made in the USA, where our quality control is second to none. We offer the only UNCONDITIONAL LIFE TIME WARRANTY in the telecommunications industry because of our oversight and commitment to excellence.

The major difference between transformer and fiber optic HVPE systems could be described as picking up a hot frying pan with a thick hot pad, verses picking it up with a thin hot pad.  Everyone knows how to pick one up, but they would prefer having the highest isolation between them and the hot pan so as not to risk getting burned.

From an electrical protection point of view, fiber optic systems offer the highest level of protection for those who have to work with communication circuits within "hot" power substation environments.
