Formula 1: 568A Equation for 850nm fiber:
(# of mated connections x 0.75) + (# of splices x 0.3) + (length x 3.75dB/1000m) = OLB*
Formula 2: 568A Equation for 1300nm fiber:
(# of mated connections x 0.75) + (# of splices x 0.3) + (length x 1.5dB/1000m) = OLB*
Formula 3: 11801 Equation for 850nm fiber:
(# of mated connections x 0.75) + (# of splices x 0.3) + (length x 3.5dB/1000m) = OLB*
Formula 4: 11801 Equation for 1300nm fiber:
(# of mated connections x 0.75) + (# of splices x 0.3) + (length x 1dB/1000m) = OLB*
*Optical Link Budget (OLB) is the loss measured in a fiber link. Loss in the
connectors, the splices, and the cable are added up to the total link loss or
OLB.
The TIA 568A Equation and the ISO 11801 Equation specify the OLB. Each
has certain PASS/FAIL criteria based on the number of connectors and
splices located along the cable to be tested. These amounts can be
entered as test limits. OMNI Scanner then calculates optical power loss as
follows: Max. Loss (dB) = Cable Loss + Connector Loss + Splice Loss.
The Optical Link Budget (OLB) is the PASS/FAIL point in dB. The number
of connections and splices is entered in the first Autotest screen.
