Filed:

Oct 2, 2000

Appl. No.:

09/677168

Inventors:

James Farmer - Lilburn GA

Assignee:

ARRIS International, Inc. - Duluth GA

International Classification:

H04B 310

US Classification:

333 15, 333 16, 327 65, 455500, 455 68

Abstract:

An apparatus ( ) for switching from a first pilot signal and a second pilot signal on a system transporting a plurality of signals. A tuner ( ) receives the signals and provides an output signal to a loop compensation circuit ( ). The tuner includes a bandpass filter ( ) for removing signals other than the selected pilot signal from the output of the tuner. The output of the bandpass filter is provided to a detector circuit ( ). The output of the detector is compared with a reference signal ( ) by the loop compensation circuit ( ). A microcontroller ( ) sends a tuning command to the tuner which causes the tuner to switch from tuning to the first pilot signal to tuning to the second pilot signal and also sends a new reference voltage to the loop compensation circuit. Thus, if the input signal changes from analog to digital modulation on the pilot channel, the set-point, or target level of the reference signal, will automatically change to provide the correct value for operation of the circuit. The microcontroller may change the selected pilot signal based upon a command in the input signal or upon an operator command, such as by setting a switch (not shown).

International Classification:

G02B 600

US Classification:

385135, 385136

Abstract:

An enclosure for facilitating and protecting splices or connections between communication transmission mediums can include a housing having a first port and a drop port. The first port can allow a distribution cable containing a transmission medium to enter the housing. The drop port can allow another transmission medium to enter the housing, and it can allow a transmission medium to be added or removed without disturbing existing transmission mediums or connections in the housing. A drop plug can be provided to seal the drop port. The enclosure can also include a cover plate having a gasket coupled to its perimeter and being removable with the cover plate. Strain relief for the transmission mediums entering the enclosure can also be provided. Two-stage strain relief and single-stage strain relief can be provided for the transmission mediums entering through the first port and the drop port, respectively.

US Classification:

398 68, 398 71, 398 72, 398135

Abstract:

An optical fiber network can include an outdoor laser transceiver node that can be positioned in close proximity to the subscribers of an optical fiber network. The outdoor laser transceiver node does not require active cooling and heating devices that control the temperature surrounding the laser transceiver node. The laser transceiver node can adjust a subscriber's bandwidth on a subscription basis or on an as-needed basis. The laser transceiver node can also offer data bandwidth to the subscriber in preassigned increments. Additionally, the laser transceiver node lends itself to efficient upgrading that can be performed entirely on the network side. The laser transceiver node can also provide high speed symmetrical data transmission. Further, the laser transceiver node can utilize off-the-shelf hardware to generate optical signals such as Fabry-Perot (F-P) laser transmitters, distributed feed back lasers (DFB), or vertical cavity surface emitting lasers (VCSELs).

Abstract:

A system and method removes heat from an enclosure or housing of a subscriber optical interface. When a subscriber optical interface housing is attached to a structure such that a partially enclosed volume of space remains between the structure and the subscriber optical interface housing, this partially enclosed volume of space can produce a chimney effect when heat from the subscriber optical interface housing is intended to flow from fins towards the structure. This chimney effect can refer to a fluid such as air within the partially enclosed space that is heated by the fins and that rises upward when the ambient or surrounding fluid is cooler relative to the heated fluid. According to another exemplary embodiment, the subscriber optical interface can be shaped to form an internal chimney structure that is entirely surrounded by a housing of the subscriber optical interface.

Abstract:

A protocol for an optical network can control the time at which subscriber optical interfaces of an optical network are permitted to transmit data to a transceiver node. The protocol can prevent collisions of upstream transmissions between the subscriber optical interfaces of a particular subscriber group. With the protocol, a transceiver node close to the subscriber can allocate additional or reduced upstream bandwidth based upon the demand of one or more subscribers. That is, a transceiver node close to a subscriber can monitor (or police) and adjust a subscriber's upstream bandwidth on a subscription basis or on an as-needed basis. The protocol can account for aggregates of packets rather than individual packets. By performing calculation on aggregates of packets, the algorithm can execute less frequently which, in turn, permits its implementation in lower performance and lower cost devices, such as software executing in a general purpose microprocessor.

Abstract:

A return path may include a modem pair that is coupled to existing electrical waveguides in a structure such as a house or office building. Specifically, a first modem of the modem pair may be coupled to a first end of a coaxial cable and to a video service terminal. A second modem of the modem pair may be coupled to a second end of the coaxial cable and a data interface. The first modem can modulate video control return packets onto an RF carrier that is propagated over the coaxial cable to the second modem. The video control return packets can be formatted as Ethernet type packets. The second modem can demodulate the RF carrier to extract the video control return packets and to forward these packets towards a data service hub.
