Abstract: A method is disclosed for testing optical fiber connection quality of an optical drop fiber between a telecommunications system and a subscriber connection box in a multi-dwelling unit or other subscriber premises before connection to other subscriber equipment. An end of the optical fiber to be tested is placed in a fiber-holding device, which holds the fiber end in alignment with a suitable reflective body. An optical signal is provided from the system direction which is reflected by the reflective body back towards the system. The reflected signal is detected by a suitable instrument, preferably an optical time domain reflectometer (OTDR), to confirm acceptable signaling quality of the optical path between the system and the fiber end.

Abstract: An optical fibre transmission distribution assembly, wherein the assembly comprises at least a first splitter having a first split ratio of 1:x (where x is an integer) connected to optical drop cables leading to subscribers, and at least a second splitter having a second split ratio of 1:y (where y is an integer and is different from x), and transfer means whereby an optical drop cable connected to the first splitter can be transferred to receive split optical signals from the second splitter, thereby enabling the signal in the transferred drop cable to be further split by addition of a third splitter at a ratio of 1:p (where p is an integer), to provide p subscriber connection points each having a 1:p*y split ratio at the subscriber end of the transferred drop cable.

Abstract: A splice closure including a frame having a partition wall to define front and rear access areas for the closure. The frame carries one or more splice trays on a first surface portion making the splices accessible from the front or first access area. A slack storage compartment is provided on the second surface portion. The slack storage compartment includes one or more pairs of opposing sidewalls that define an access opening for the slack that is accessible from the rear access area. An extension member for the frame is disclosed for obtaining greater amounts of slack from the cable, such as for a taut sheath cable splice. A tandem longitudinal arrangement of splice trays is also disclosed and may be used for a taut sheath ring splice or for repairing a severed cable. A method is disclosed for making a taut sheath optical fiber splice to the severed cable.
