The fiber connection must conform to both the Optical Budget and Fiber Length specifications. It
is possible to have a fiber connection longer than 3 km with less than 9 dB of loss; however, the
CTX670 Remote Expansion Cabinet is sensitive to signal delay and cannot be guaranteed to
operate at distances greater than 3 km.
