MODULE FOR NETWORK INTERFACE CARD

摘要

A telecommunications interface network card, such as the type which is inserted into a suitable slot in a rack forming a network node, to provide an interface to the node for telecommunications traffic entering and leaving the node, typically carries a receptacle to receive a plugable module which contains a laser and receiver as optical interface, allowing one card to be used with a number of optical interfaces, to avoid the need for a range of cards to be produced, each dedicated to one particular type of traffic, for example, a particular distance and data rate. The invention provides a module which is compatible with existing optical modules, but which carries an electrical interface.
