摘要： 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.

摘要： 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.

摘要： 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.

The first optical power amplifier includes an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the first portion of light from the splitter is coupled into the optical fiber input of the first optical power amplifier. The second optical power amplifier includes an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the second portion of light emitted from the splitter is coupled into the optical fiber input of the second optical power amplifier.
