Embodiment Construction

[0012] with reference to the attached figure 1 and figure 2 , a telecommunications network interface card 1 having a row of contacts 2 to cooperate with contacts in a node such as an access hub. The card carries circuit components (not shown) such as integrated circuits. The card also carries a carrier 3 for pluggable modules such as SFPs. Such SFPs typically constitute the optical interface for the card. The carrier 3 is a sleeve in the form of a rectangle, the long side of which is located on the front of the card. The sleeve is open to receive the SFP at its end closer to the card edge. Normally, the card would be mounted with its plane perpendicular in the node, with the contacts engaging those in the node. The SFP will be received into the left hand end and will engage the contacts towards the right hand end.

[0013] According to the invention, the pluggable module 4 is designed so as to be able to be plugged into a known carrier, but the module has an electrical ...

Abstract

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.

Description

technical field [0001] The present invention relates to pluggable modules for telecommunications network interface cards. Such cards are inserted into appropriate slots in racks to form network nodes, such as access hubs. The card provides an interface to a hub for telecommunication traffic entering or leaving the card, and the hub provides inter alia communication between the cards through the backplane. The access hub communicates with other nodes of the network. Background of the invention [0002] The telecommunication traffic entering the card can be optical and of various bit rates (e.g. 155Mbit / s, 622Mbit / s etc.) Short distance interconnections with cost advantages (for example, if the access hub will be connected to another device in the same building). Traditionally, transport interfaces have been designed on a custom basis, with circuits designed into the host card where they belong. Thus, a particular card may have a photosensitive receiver and a laser of a se...
