초록 ▼

An optical interface includes a rack mountable enclosure that includes multiple slots for retaining multiple insertable fiber optic (FO) modules. The FO modules include a first set of interconnection ports that connect to remote radio units (RRUs), a second set of interconnection ports that connect to a baseband unit (BBU), and a third set of monitoring ports that connect to monitoring/text equipment. The FO modules contain fiber splitters that split off uplink/receive and downlink/transmit signals carried on optical fibers to the third set of monitoring ports. The FO modules may insert in different orientations and directions into different rack mountable enclosure configurations for higher density and more configurable connectivity. A splitter holder is located within the FO module and provides improved optical fiber routing for more integrated module port interconnectivity.

The optical fiber module of claim 1 including a splitter holder located within the modular container including multiple channels each retaining the fiber splitters and optical fibers associated with a different one of the RRUs. 8. The optical fiber module of claim 7 wherein some of the optical fibers wrap around rounded ends of the splitter holder. 9. The optical fiber module of claim 7, wherein the splitter holder includes an oval shaped profile with flat top and bottom sections and round ends sections extending between the top and bottom sections. 10. The optical fiber module of claim 9, including: a first set of optical uplink fibers extending from the first set of interconnection ports, over the flat top section of the splitter holder, and to first ends of an upper set of the fiber splitters located on the flat top section of the splitter holder;a second set of optical uplink fibers extending from second ends of the upper set of fiber splitters, around one of the round end sections and along the bottom section of the splitter holder, and connecting to one of the second set of interconnection ports; anda third set of optical uplink fibers extending from the second ends of the upper set of fiber splitters, along the top section of the splitter holder and connecting to the third set of monitoring ports. 11. The optical fiber module of claim 9, including: a first set of optical downlink fibers extending from the second set of interconnection ports, along the bottom section of the splitter holder, and to first ends of a lower set of the fiber splitters located on the bottom section of the splitter holder;a second set of optical downlink fibers extending from second ends of the lower set of fiber splitters, around one of the round end sections and along the top section of the splitter holder, and connecting to one of the first set of interconnection ports; anda third set of optical uplink fibers extending from the second ends of the lower set of fiber splitters, along the bottom section of the splitter holder and connecting to the third set of monitoring ports.
