CERTIFICATION METER - Creating User-Definable Cabling Standards
Some companies have their own set of optical fiber loss parameters – such as fiber loss, connector loss and
splice loss – that they need their network to adhere to. Thus, the FiberMeter allows the user to configure two
user-definable cabling standards for the purpose of fiber certification.
These standards are defined when selecting the fiber standard during the Link Wizard process.
NOTE: one of the key parameters for defining these custom cabling standards is fiber loss (dB per kilometer).
Each custom standard supports a different range of optical losses (for up to 2 wavelengths), thus it is important
to know what the fiber loss is because this determines which user-definable standard to use.
USER DEFINED #1 supports fiber losses for up to two wavelengths from 0.01 dB to 2.55 dB per kilometer
USER DEFINED #2 supports fiber losses for up to two wavelengths from 0.1 dB to 25.5 dB per kilometer
