OPTICAL JUMPER UNIT

摘要

PROBLEM TO BE SOLVED: To provide an optical jumper unit that includes a wavelength selective optical filter capable of transmitting communication light having a wavelength up to 1625 nm and blocking test light of a U-band.SOLUTION: An optical jumper unit includes a wavelength selective optical filter 2132 provided on a side of ports for an N-SLT (N-system Subscriber Line Terminal) in an optical multiplexer/demultiplexer which multiplexes or demultiplexes communication light of an S-band outputted from the N-SLT and communication light of a C-band outputted from a V-SLT (V-system Subscriber Line Terminal). An installation angle α of the filter relative to a vertical cross section of a target optical fiber 2131 is 5.5° or more and 6.0° or less.SELECTED DRAWING: Figure 5
