Note1: All values specified are without connectors.
Note2: Higher performance specifications are available upon request.
Note3: Fiber type Corning SMF-28e.
Note4: Channel count is from low to high for mux and high to low for demux if mux & demux are packaged in one cassette. In this
case the first channel & last channel in P/N is for mux
