Problems solved by technology

However, for extremely small separator modules, it is not feasible to fit any additional devices inside the module housing
Also, the cost of the splitter module will be increased by the cost of the attenuator
In addition, the reliability of the attenuated splitter module will be affected by the additional attenuation device

Embodiment Construction

[0020] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, in which some but not all are shown. Indeed, the concepts may be embodied in many different forms and should not be construed as limitations herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Wherever possible, the same reference numerals will be used to refer to the same components or parts.

[0021] One of the most commonly used devices for fiber-to-the-home (FTTH) applications is the 1x32 and 1x16 splitter modules. The network architecture was designed based on the power transmitted through the devices with insertion losses of 15dB and 12dB, respectively. However, not all output fibers may be required by the network. Possible use of 1x4 and 1x8 splitter devices. The insertion loss of 1x4 and 1x8 splitter devices can be 6dB and 9dB respectively, resulting in transmit power that is to...

Abstract

A splitter module (100), comprising an enclosure and a splitter device (104(1) and 104(2) with one or more splitter legs (108) mounted in the enclosure. Each splitter leg has an optical fiber (112) therein extends for a certain length from the splitter. At least one of the splitter legs, and, thereby, the optical fiber, is cut. The cut may be at an angle to the longitudinal axis of optical fiber. The angle may be about 45 degrees. The coating may be stripped off such that the cut end of the optical glass fiber of the at least one output leg is exposed a certain distance. The cut end of the optical glass fiber positions in the interior of the enclosure. A glass-index-matching material, at least partially fills the interior of the enclosure such that the cut end of the optical fiber is embedded in the glass-index-matching material.

Description

[0001] Related applications [0002] This application claims the right of priority under the Patents Act to U.S. Provisional Application No. 61 / 530,687, filed September 2, 2011, the contents of which are the basis of this case and are incorporated by reference in their entirety. into this article. technical field [0003] The technology of the present disclosure relates to splitter modules and related assemblies and methods for attenuating optical signals in unused splitter branches. Background technique [0004] The optical splitter unit is installed inside the splitter module for use in FOH cabinets and closures. Splitter modules are typically bulky due to the many pigtailed cables exiting the module housing. The size of the splitter modules is not an issue in FTTH applications for community and residential complexes where larger enclosures are installed in outdoor spaces. [0005] Multi-dwelling unit and high-rise building applications with building space constraints c...
