1. A cable arrangement comprising:
an optical cable extending between opposite first and second ends, the first end being terminated at one single-fiber plug connector, and the second end being terminated at one plug connector;
a sealed enclosure disposed along the optical cable between the first and second ends so that a first portion of the optical cable extends out of the sealed enclosure to the first end and a second portion of the optical cable extends out of the sealed enclosure to the second end; and
a wave division multiplexer disposed within the sealed enclosure, the wave division multiplexer being configured to multiplex optical signals carried over the optical cable to the first end and to demultiplex optical signals carried over the optical cable to the second end.
 
12. An optical system comprising:
a signal source;
a plurality of subscribers including a plurality of network subscribers and a dedicated subscriber;
a fiber optic network extending between the signal source and the plurality of subscribers;
a drop terminal disposed along the fiber optic network, the drop terminal including a plurality of output ports;
a drop cable extending from a first of the plurality of output ports of the drop terminal to a first of the plurality of network subscribers to carry power split optical signals to the first network subscriber; and
a cable extending from a second of the plurality of output ports of the drop terminal to the dedicated subscriber to carry wavelength split optical signals to the dedicated subscriber, the cable extending fully between two plug connectors, wherein the cable or the two plug connectors include a wave division multiplexer configured to generate the wavelength split optical signals.
