A data communication system for deploying outside plant fiber optics includes a cassette releasably engageable in a tray pivotably connectable to a tray fastening member disposed in an inside of an enclosure. A test port in the cassette is accessible without pivoting the tray and without pivoting any one or more trays pivotably connected to the tray fastening member.

A fiber optic hardware module includes an enclosure including a planar floor section, outer sidewalls adjoining the floor section and extending from the floor section to top edges, and a detachable top panel that covers an interior volume that is defined by the outer sidewalls and the floor section. Fiber optic cable ports are disposed on a first outer sidewall and feed into the interior volume. First and second mounting tabs are configured to secure the fiber optic hardware module to a planar surface that is flush against the floor section. A third mounting tab is configured to secure the fiber optic hardware module to a planar surface that is flush against the top panel. The third mounting tab is vertically offset from the first and second mounting tabs. The third mounting tab is laterally between the first and second mounting tabs.

A conduit for passing fiber optic cables through a fiber optic shelf includes a floor section and two sidewalls joining opposing sides of the floor extending towards a top of the conduit. The sidewalls and floor form a u-shaped enclosure having an opening at the top. A fastening anchor having a first tab joins the floor and extends away from the top perpendicular to the floor. A fastener perforation on the first tab is dimensioned to receive a fastener for affixing a fiber optic cassette to a fiber optic shelf. An engagement anchor joins the floor at an opposite end from the fastening anchor and extends away from the top. A protrusion on the engagement anchor extends towards the first tab so as to engage a fastener perforation of a mounting rail in the fiber optic shelf and secure the conduit to the mounting rail.

A system for mounting a plurality of fiber optic cassettes includes an enclosure and angle-iron-shaped elongated members that are affixed within the enclosure and vertically spaced apart. The elongated members include shelf fastener perforations disposed at regular intervals along a mounting surface and arranged to horizontally and vertically align with fastener perforations of one of the fiber optic cassettes. The system further includes a plurality of adapter brackets. Each of the adapter brackets include first and second generally planar sections spaced apart from one another and a third section joining the first and second sections. The third section includes a bracket fastener perforation. First, second and third stabilization features protrude from the first and second planar sections and are collectively arranged to secure the adapter bracket to one of the elongated members and to simultaneously allow the adapter bracket to move in a horizontal direction without substantial resistance.

System for mounting a plurality of fiber optic cassettes to a high density cassette shelf

Optical equipment for 1G-EPON, 10G-EPON, and CWDM services are joined together using a novel combination of optical power splitters and multiplexers. This combination of splitters and multiplexers can be disposed in a single housing, which reduces the size of the combination and improves performance, since jumpers between multiple, separately packaged, optical components can be avoided. One example of the inventive techniques and circuits disclosed herein is a combiner/separator circuit for combining and separating 1G-EPON and 10G-EPON signals. In the example application detailed herein, where EPON equipment is combined with CWDM equipment, an important advantage of this optical circuit is its ability to provide return wavelength isolation for EPON systems that have separate ports for 1G and 10G services.
