A method of assembling a fiber access terminal. A fiber access terminal assembly including a pedestal mounting arrangement.

Fiber access terminal

A multi-port optical connection terminal for use as a branch point in a fiber optic communications network at a distance from a mid-span access location provided on a distribution cable having a plurality of optical fibers. The multi-port terminal includes a base and a cover affixed to the base. A stub cable port formed through one of the base and the cover receives a stub cable having at least one optical fiber extending continuously from the multi-port terminal to the mid-span access location. A first end of the optical fiber is optically connected to a respective optical fiber of the distribution cable at the mid-span access location and a fiber optic connector is mounted upon the second end. At least one connector port is provided on the multi-port terminal for receiving the fiber optic connector and a connectorized end of a fiber optic drop cable extending from the multi-port terminal.

Multi-port optical connection terminal

An outside plant fiber distribution apparatus includes a frame member and a plurality of fiber optic modules mounted to the frame member. The frame member includes upper and lower module mounting brackets. Each module includes a front and two mounting flanges, each mountable to one of the upper and lower module mounting brackets. At least one of the modules is configured as a connection module including a plurality of connection locations disposed along the front of the module. A rear of the module includes a cable notch region for receipt of a cable. At least one of the modules defines a storage module including first and second spools. In an interconnect system, the storage module includes a cable clamp for holding a second cable, the cables are connected through the connection locations of the connection module. In a cross-connect system, two connection modules are provided, and patch cords are used to connect the fronts of the connection modules. The modules may also house splices, and/or optical couplers, such as splitters and wave division multiplexers.

Outside plant fiber distribution apparatus and method

A drop terminal mounting system includes a fiber drop terminal having a housing and a base attached to the housing. The housing includes an outer surface containing a plurality of receptacles and cooperatively defines an inner cavity with the base. The drop terminal mounting system further includes a bracket having a first fastening region and a second fastening region adapted to secure the drop terminal to the bracket.

Fiber drop terminal

An optical fibre organizer having a plurality of substantially mutually adjacent inlet ports and a plurality of mutually separated outlet ports, and means connecting the inlet ports and the outlet ports such that a fibre inserted into each inlet port will emerge from a predetermined outlet port.

Optical fibre organizer

An optical fibre management system comprises a plurality of splice trays (4) arranged in a stack. Each splice tray (4) has a main body portion (9) for holding at least one splice, and for storing fibres leading to the splice(s), and a fibre entry/exit portion (10) for feeding fibre to/from the main body portion. Each tray (4) is mounted in the stack so as to be movable from a stacked position, in which it is aligned with the other trays, to first and second operating positions in which the fibre entry/exit portion (10) and the main body portion (9) respectively are accessible.

Optical fibre management system

A method and apparatus for installing optical fibres (11) in tubes or ducts (29). An optical fibre is fed from a reel (13) into a small diameter feed portion of duct (25), and compressed air is introduced into the duct. This advances the fibre, using viscous drag forces, into a main duct of larger diameter. There is a pressure drop at the intersection of the two ducts. Subsequently, the advancement of the fibre is continued by maintaining the air supply, and the viscous drag forces, acting on the increasing length of the fibre in the duct, advance it along the duct. Two or more fibres, which may be unsheathed primary coated fibres, may be installed simultaneously.

Transmission line installation

The propulsive force on an optical transmission line member moving through a tubular passageway can be varied so the line travels at or close to optimum speed without risk of damage to the line or associated apparatus. A curve is provided in a portion of the passageway such that a transmission line subject to unacceptable compressive forces buckles towards the outer side of the curve. A sensor detects the presence or absence of the line at this point and a control circuit varies the propulsive force. Excessive tension in the fibre may also be detected. A modified system uses deflectors to ensure that buckling occurs by bowing in the direction towards the sensor with the transmission line undeflected under correct tension. The invention finds particular application in a method of fibre blowing where an optical fibre transmission line is propelled along a tube by fluid drag.

Control method and apparatus

A break-out tray (T) is disclosed for separating the fibre end portions formed by cutting one or more fibres of a multi-fibre cable (C) from the remaining fibres in the cable. The break-out tray (T) includes means (B) for guiding the fibre end portions to a fibre exit portion of the tray, and means (3) for storing a length of uncut cable.

Break-out tray

A splice organiser comprises a tray having a plurality of formers (14, 15) which control the minimum bend radius of the fibres, a groove for retaining a splice, an enclosure into which coiled fibre loops are introduced and permitted to expand so that they are retained by the resilience of the fibre itself, and a plurality of guide tracks (23, 24, 25) which enable fibres to enter and exit the organiser at any corner of the tray.
