Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to provisional application number 63 / 051,105 filed on July 13, 2020.FIELD

[0002] The present disclosure relates generally to splice closures for fiber optic networks.BACKGROUND

[0003] Today, the Multiple System Operators (MSOs) (CATV Service providers) and Telephone Operating Companies (TELCOs) are increasing the available bandwidth to their consumers by reducing the number of subscribers that are sharing the bandwidth and pathway. For example, in the MSO world reducing the number of subscribers from 512 to 256 subscribers at a service node doubles the bandwidth and allows for faster internet access for each of the remaining customers. Additionally, the TELCOs reduce the fiber infrastructure requirements by using splitters and Coarse Wavelength Division Multiplexing (CWDM). To increase this rate or available bandwidth, the MSO or TELCO will add additional pathways by using different fundamental wavelengths over the existing fiber. This is done with the use of either optical filters to selectively access specific wavelengths, coarse wavelength division multiplexers (CWDM) devices, Dense Wavelength Division Multiplexing (DWDM), or any other wavelength division multiplexing (WDM) devices. Today, when this is done in an Outside Plant (OSP) location, these devices are incorporated into an optical splicing closure and mounted to a fiber optic splicing tray. The method adds significant additional cost and causes congestion in the closure that is already used to splice the reel ends and branch splice points of fiber optic cable. This combination of components, the closure, splice tray, and PLC device is assembled in the field by the MSO or TELCO personnel. With multiple cables and branch splices these splice closures are very congested, even prior to introducing an optical filter or WDM device that will take up space in a dedicated splice tray to connect the input fiber and the output fibers. This method either causes too much congestion or requires an auxiliary closure to be stubbed with a short section of fiber optic cable and sufficient fiber to address the incoming and outgoing fiber for the optical filter or WDM device.

[0004] Accordingly, improved splice closures for fiber optic networks are desired in the art. In particular, improved splice closures for fiber optic networks which provide reduced defects, fewer errors, reduced cost, improved quality, and improved impact resistance would be advantageous.

[0005] US 2018 / 081136A1 discloses a system including a terminal comprising feeder and distribution ports configured to receive a connector to interface with a drop type cable. The terminal comprises an expandable module that is configured to receive a splitter, where the terminal is configured to be mounted aerially. The terminal is configured to receive a fiber through the feeder port and to output a set of fibers through the set of distribution ports.BRIEF DESCRIPTION
