Wavelength-Division Multiplex Small Form Factor Pluggable (PXFP-WDM) Optical Transmitter Module Interface Specification

Many service provider networks are fiber constrained. The cost of fiber construction is prohibitive in most applications and many service provider systems have link distances that significantly exceed 20 km. The use of a PON Extender architecture utilizing WDM optics enables multiple 10G PON links to be deployed on different wavelengths over a single fiber at distances much greater than 20 km.

WDM pluggable optics compatible with PON OLT line cards enable a multi-wavelength link between the OLT platform and a PON Repeater. This standard defines these optics for use in PON OLTs.
