dcmFiberCoefficient
Module: SL-DCM-MIB
OID (symbolic): SL-DCM-MIB::dcmFiberCoefficient
OID (numeric): 1.3.6.1.4.1.4515.1.14.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The fiber chromatic dispersion coefficient. For example the chromatic dispersion coefficient value for G.652 fiber is 17 ps/(nm km). For G.655 is 6 ps/(nm km) For G.656 is 14 ps/(nm km) The default value is 17.
What is dcmFiberCoefficient?
This read-write Integer32 sets the chromatic dispersion coefficient of the fiber type being compensated, in ps/(nm km), defaulting to 17 (matching G.652 fiber; G.655 is 6, G.656 is 14). An admin sets this to match the actual fiber type deployed on the link, since using the wrong coefficient would cause the DCM to under- or over-compensate dispersion. Setting it to 6 for a G.655 fiber deployment ensures the DCM's range calculation uses the correct dispersion coefficient for that fiber.
