Abstract: A Raman pump module for generating pump radiation having a pump wavelength (λp) for coupling into a transmission fiber of an optical wavelength division multiplex (WDM) communication system to provide Raman amplification of WDM radiation counter propagating therethrough is disclosed. The pump module is for use in a communications system in which the WDM radiation has a transmission waveband (λs) and wherein the transmission fiber has a zero dispersion wavelength (λm) lying midway between the transmission waveband and the pump wavelength. The module comprises a Raman pump laser for generating the pump radiation and a de-correlator for de-correlating the longitudinal modes of the pump radiation before it is coupled into the transmission fiber.

Abstract: Dynamic allocation of connections is performed in a communication network. When a new connection request is received by the network management system this request can be accepted or rejected. In case it is accepted, the connection can be set up by allocating new or reconfiguring existing connection resources. The reconfiguration options are constrained to a set of allowed reconfigurations which is a subset of the set of all possible reconfigurations of the existing connections on the network.

Abstract translation: 在通信网络中执行连接的动态分配。 当网络管理系统接收到新的连接请求时，可以接受或拒绝该请求。 在被接受的情况下，可以通过分配新的或重新配置现有连接资源来建立连接。 重新配置选项被限制为一组允许的重新配置，这是网络上现有连接的所有可能重新配置的集合的子集。

Abstract: A 1550 nm DWDM optical communications network has a 1300 nm remote node added to which a small number of channels can be added or dropped. The additional node includes dual wavelength couplers to enable 1300 nm wavelength signals to be added or dropped. The 1300 nm signals are demultiplexed using a WDM filter and connected into the transponders of the 1550 nm nodes for transportation around the node. Signals for the remote network are converted to 1300 nm signals at the 1550 nm node transponders and multiplexed onto the network to be dropped to the network node transponder.

Abstract: An optical communications system using forward error correction (FEC) to correct errors in signals carried by the system. Optical signals on the system are dropped at nodes and converted to electrical signals by avalanche photodiodes (APDs) at the node receivers. An FEC chip operates on the electrical signal to correct errors. The error rate is used to control the APD bias voltage which affects signal noise and therefore error rate. The errors in a predetermined interval are counted and a determination made as to whether the error rate is rising with time. The bias voltage is derived from the value of a counter whose count is incremented each interval. If the error rate is rising, the counting direction is changed.

Abstract: An apparatus for determining a best number, representing a maximum or minimum of a set of numbers, includes a first comparator 3 having a latency of at least one clock cycle to compare a current number with a current best score and to output a corresponding first comparator signal 7 and at least a second comparator 13 having a latency of at least one clock cycle to compare the current number with any other input number compared with a current best number while the current number was being processed through the apparatus and to output at least a corresponding second comparator signal 18. A combinatorial logic block 15 receives the comparator signals and outputs a corresponding signal 20 dependent thereon and on a flag signal 21 received from flagging means arranged to flag whether the current best number was updated for one or more preceding input numbers while the current number was being processed. A switch 6 outputs either the current best number, or the current number, as a new current best number, dependent upon the combinatorial logic block signal. A resultant reduction in logic steps processed in each clock cycle permits an increased clock frequency compared with the prior art.
