1. Both CO (Central Office) and SUB (Subscriber) interface ends of a Fiber Optic Link Short Haul installation will necessarily be located inside of the high voltage area. Therefore, the Fiber Optic Link equipment must be mounted on an all dielectric platform such as a 3/4" plywood backplane.
   
2. ALL Fiber Optic Link CO Cards CAN BE powered via the copper telco pairs. However, your telco must have power available on ALL pairs.
3. ALL Fiber Optic Link CO Cards (except 2W POTS) can also be powered via 24-48 VDC connected to auxiliary terminals on the Cards. However, to maintain electrical isolation between CO and SUB interfaces, Short Haul CO AND SUB CARDS CANNOT BE POWERED FROM THE SAME SOURCE.
4. ALL Fiber Optic Link SUB Cards (except 2W POTS) are powered via 24-48 VDC connected to auxiliary or PS terminals on the Cards. 2W POTS Cards can only be powered via 24 VDC.
5. The maximum fiber optic cable length for Short Haul Fiber Optic Link Equipment is 66 feet (20 meters). The maximum fiber length for T-1 Cards is 33 feet (10 meters).

Ordering Hints:

1. Part Number example: 8806-1232-03.
   

   The first four digits of the part number (8806) indicate the product line, i.e., Fiber Optic Link.
   
   The next two digits of the part number indicate whether the card processes analog information (12XX) or digital information (13XX).
   
   The next two digits indicate the type of card. Thus, XX32 would indicate a 2 Wire (POTS) Card; XX33 indicates a 4 Wire Data Card.
   
   Finally, the last two digits indicate the model number. This is only important to RLH since most models are BACKWARD COMPATIBLE.
   
   Therefore, the card in the example above is a Fiber Optic Link, analog, 2 Wire (POTS) Card, Model 3.
   
   
   
2. To aid in ordering, CO and SUB Cards for the SAME service are ALWAYS 10 digits apart. Thus, the 2 Wire CO Card is part number 8806-1232-03. The part number for the corresponding 2 Wire SUB Card is 8806-1242-03. Every service type must have a CO and SUB Card.
   
   
3. Fiber Optic Link UNITS consist of a Fiber Optic Link Card INSTALLED in a Single Fiber Optic Link Housing. The part numbers for CO and SUB UNITS are ALWAYS CONSECUTIVE with the SUB unit having the lower number. Thus, a Fiber Optic Link 2 Wire SUB Unit will have the part number 8806-1201-03. While the 2 Wire CO Unit will be numbered 8806-1202-03.
