Abstract
A passive optical network includes one or more multi-service terminals each having a housing and a plurality of ruggedized plug-receiving distribution ports accessible from outside the housing. The multi-service terminals also each include an optical power splitter or wave division multiplexer for splitting an optical signal and directing the split signal to the plug-receiving distribution ports. Some of the multi-service terminals provide a different power split ratio from others of the multi-service terminals.
Claims16
An optical system comprising:
- a first enclosure that receives a first optical cable, the first enclosure defining a sealed interior;
- an optical circuit disposed within the sealed interior of the first enclosure, the optical circuit configured to split power from optical signals carried over the first optical cable into two split signals;
- a second enclosure separate from the first enclosure, the second enclosure defining a sealed interior containing an optical power splitter, the second sealed enclosure including a plurality of ruggedized optical ports;
- an optical fiber that carries a first of the split signals from the first sealed enclosure to the second sealed enclosure, wherein the first of the split signals is input at the optical power splitter, wherein the optical signals carried over the optical fiber are not further split between the optical circuit and the second enclosure;
- and
- an optical distribution cable that carries a second of the split signals away from the first sealed enclosure.
