Described herein are devices and methods for facilitating the transmission of an upstream data signal from at least one subscriber in a communications network. The device is operable to receive a radio frequency (RF) signal from one or more subscribers. The RF signal includes at least one upstream data signal. The RF signal is demodulated into the upstream data signal by a RF demodulator in the device, which is then converted into an optical signal by an optical transducer in the device for transmission over a fiber optic link in the network.

A modular electronic chassis system with nested electronic plug-in modules including at least one circuit board providing a first-module-receiving-location and a second-module-receiving-location such that the system is capable of supporting modules in a nested configuration having increased packaging density. A first plug-in module detachably engaged with the first-module-receiving-location. A second plug-in module detachably engaged with the second-module-receiving-location so that the first plug-in module and the second plug-in module are nested.

A fiber optic cable tray comprising a platform substantially encircled by a peripheral wall extending from the platform. An internal wall extends across the platform and defines first and second chambers and a passage therebetween. The fiber optic cable passes from the first chamber, through the passage, and through the second chamber. A retainer positioned in the passage receives and arrestingly engages the fiber optic cable as it passes from the first chamber to the second chamber, thereby fixing the length of the portion of cable passing through the second chamber.
