CONNECT FIBERS TO OPTICAL CARDS
Summary: This procedure describes the processes required to properly connect the inbound and outbound fiber optic cables to the correct ports on the optical cards. The optical connector configurations may vary from SC, ST, or FC fiber connectors, dependent upon the type of equipment ordered. Optical cards include the 2488, 622, and 155 RICs and the 155 SM/MM CRS cards. Note that on the 155 SM/MM CRS cards, there are two ports that may be utilized. If ordered, fiber connector adapters may be changed out on the RIC and 155 SM/MM CRS cards. The 155 MM card does not have a modular adapter.
Danger: Do not look into the ends of optical fibers. Exposure to invisible LASER radiation may cause serious retinal damage or even blindness. Verify the optical source is disabled through the use of an optical power meter before handling optical fibers.
Caution: Use caution when routing wires and cables. Avoid severe bending and routing over sharp edges. Use grommet material when possible to avoid wear on cable insulation.
Caution: Allow sufficient fiber length to permit routing without severe bends. Fibers may be permanently damaged, or signal degradation may be experienced if fibers are bent or curved to a radius of less than 1.5 inches (3.81 cm).
Caution: Modules can be damaged by electrostatic discharge. Before handling any modules connect your wrist to an equipment ground using an approved
Caution: Using excessive force when seating cards and modules into the backplane may result in physical damage to the backplane pins or module connectors, and if power is applied, may result in serious electrical damage to both the modules or the backplane.
A. Fiber Routing
1.Check site plans to determine the fiber connection required. The RIC cards and 155 CRS SM/MM optical cards have modular adapters that can be changed to meet customer applications for either FC, SC, or ST type connectors. These adapters must be ordered separately if changes are required. The 155 CRS MM cards will be equipped per customer requirements from the factory as should the RIC and 155 CRS SM cards. Refer to Figure
2.Tag and identify the optical fibers from the source (fiber distribution panel, etc.) before routing them to the Cellworx STN shelf (ex. 155/622, Clockwise/Counterclockwise, Slot no., In/Out, rack no., etc.)
