Abstract
A blade-type optical transmission apparatus includes a plurality of main-signal blades, each of which is provided with an external optical signal interface unit, a cross-connect unit, and an internal optical signal interface unit, a blade enclosure in which the plurality of main-signal blades are enclosed, and a back plane which is situated inside the blade enclosure and provides a ring connection for the internal optical signal interface unit between the main-signal blades.
Claims7
A blade-type optical transmission apparatus, comprising:
- a plurality of main-signal blades, each of which is provided with an external optical signal interface unit, a cross-connect unit, and an internal optical signal interface unit;
- a blade enclosure in which said plurality of main-signal blades are enclosed;
- a back plane which is situated inside said blade enclosure and provides a two-fiber ring connection for the internal optical signal interface unit between the main-signal blades, wherein the two-fiber ring connection has two fibers connecting between each two adjacent ones of the main-signal blades;
- and
- a bypass blade, which is attached to a portion of said blade enclosure that is configured to receive one of the main-signal blades, and partitions the ring connection provided by said back plane.
