| 20090214202 | Selecting Wavelengths And Routes In An Optical Network - Selecting a wavelength and a route includes facilitating communication through routes among nodes. Each route is associated with a plurality of wavelengths and comprises one or more segments that couple one node to another node. A polarization mode dispersion value is determined for each wavelength of each route to yield polarization mode dispersion values for each route. A wavelength and a route are selected according to the polarization mode dispersion values. | 08-27-2009 |
| 20090245805 | System and Method for Communicating Wireless Data Utilizing a Passive Optical Network - In one embodiment, a method for providing wireless communications utilizing a passive optical network (PON) is disclosed. The method includes receiving, at a PON, downstream packets from a base station destined for a mobile station, and transmitting the downstream packets to wireless transceivers associated with PON. The method also includes receiving, at the first wireless transceiver communicatively coupled to a first optical network terminal (ONT), the downstream packets from the first ONT and transmitting a first wireless signal comprising the downstream packets to a first cell. The method also includes receiving, at a second wireless transceiver communicatively coupled to a second ONT, the downstream packets from the second ONT and transmitting a second wireless signal comprising the downstream packets to a second cell. | 10-01-2009 |
| 20110043897 | Optical Amplifier Card with Pluggable Pump Laser Modules - A system for optical communication including an optical amplifier card configured to receive a plurality of pump laser modules. The optical amplifier card includes a receptacle configured to receive the pump laser module, a connector configured to couple the pump laser module to the optical amplifier card, a monitor configured to measure at least the optical output power of the pump laser module, and a pump combiner communicatively coupled to the monitor. The pump combiner is configured to receive a signal from the monitor indicating a drop in the output power of a first pump laser module below a threshold level, and, in response to the signal, switch the optical amplifier card from using the optical power of the first pump laser module to using the optical power of a second pump laser module without substantially affecting normal operation of the optical amplifier card. | 02-24-2011 |
