Abstract: In one embodiment, a method is performed by a wireless station. The method includes determining that a wireless network provides relay service. The wireless network includes an access point and one or more relay nodes. The method further includes transmitting a relay-service desirability indication to the access point. The method also includes receiving a relay-service confirmation from the access point. The wireless station is operable to transmit at a first station-transmission power level during a first time period and a second station-transmission power level during a second time period. The second station-transmission power level is a reduced station-transmission power level as compared to the first station-transmission power level. In addition, the method includes transmitting an uplink transmission at the second station-transmission power level responsive to the relay-service confirmation from the access point.

Abstract: The present invention discloses a method for classifying the packets into two divisions in the IP network. The first division is for the packets of constant packet rate (CPR) flows, and another division is for non constant packet rate (NCPR) flows. The method comprising: controlling the sending packet rate of CPR flows; classifying and queuing the CPR packets into the first division and all other NCPR packets into the second division; using FQ (or WFQ) algorithm to schedule the packets from the two divisions. In the present invention, CPR flows and NCPR flows share the transmission media by using two different entities. In each computing node, packets of CPR flows have guaranty delivery without packet drop. Previous QoS methods, such as priority method, can be used inside the two divisions for QoS purpose.

Abstract: An optical waveguide for use in amplifying light signals with an integrated gain equalization filter. The optical waveguide includes a gain section for amplifying light signals.

Abstract: An optical amplifier utilizes two or more doped fiber segments or portions to achieve a lower noise figure and a higher saturation power than would be possible using any one of the doped fiber segments. Each doped fiber portion may be considered to be a doped fiber optical amplifier, and has a different doping level than each of the other doped fiber portions. Each such doped fiber portion has distinct amplitude gain and noise characteristics relative to each of the other doped fiber potions. The two or more doped fiber portions are coupled to each other in series and most often in a predefined order based on their relative amplitude gain, noise and saturation power characteristics.

Abstract: A variable optical attenuator. A PIN structure is integrated with an optical detector such as a PIN diode or an APD diode. When the PIN structure is forward biased, the light signal is not affected and is detected by the optical detector. When the PIN structure is reverse biased, the light signal is attenuated and the dynamic range of the optical detector can be increased.

Abstract: Erbium doped fiber amplifiers for dense wavelength division multiplexed (DWDM) metro area optical networks may be configured as either high gain amplifiers or power amplifiers. The erbium doped fiber type, length, and pump power level are selected so that the shape of the gain spectra is approximately the same for single channel or multi-channel operation. In one embodiment, the same erbium doped fiber type and length is used for both power amplifiers and high gain amplifiers, reducing manufacturing costs.
