"Programmable Small Form-Factor Pluggable Module" in Patent Application Approval Process

February 12, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- A patent application by the inventors Robitaille, Claude (St-Placide, CA); Ostiguy, Patrick (Lachine, CA), filed on July 18, 2012, was made available online on January 30, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Accedian Networks Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "An SFP is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It generally interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. The following description is based on an optical SFP, but it should be understood to cover any type of SFPs."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In accordance with one embodiment, a small form factor pluggable ('SFP') transceiver for use in a communications network includes a transmitter adapted to be coupled to the network for supplying signals to the network, a receiver adapted to be coupled to the network for receiving signals from the network, and a programmable signal processing module coupled to the transmitter and the receiver and adapted to be programmed from a remote station coupled to the network, the module being programmable to perform at least one service and management functions on the network. The programmable signal processing module may be a field programmable gate array or an application specific integrated circuit.

"In specific implementations, the programmable signal processing module is programmable to perform at least one service assurance function on the network. such as monitoring network traffic and diagnosing issues (e.g., performing remote in-service Layer 1-4 loopback, ITU-T Y.1564 and RFC-2544 performance testing), and/or monitoring actual customer statistics from a web browser or portable test set. The programmable signal processing module may also be programmable to perform service management functions on the network, such as policing, traffic shaping and VLAN mapping.

"The programmable signal processing module may be programmed to listen to traffic on the network, to detect a predetermined message broadcast by a remote device coupled to the network, and to respond to the predetermined message to indicate that the module is coupled to the network and is functioning. Communications with the remote device may be without the use of IP protocols over an ISO Layer 2 network.

BRIEF DESCRIPTION OF THE DRAWINGS

"The invention may best be understood by reference to the following description taken in conjunction with the accompanying drawings.

"FIG. 1 is a diagrammatic illustration of an SFP optical transceiver.

"FIG. 2 is a diagrammatic illustration of an SFP optical transceiver that includes an inline programmable module such as a FPGA.

"FIG. 3 is a diagrammatic illustration of an adapter device that includes an SFP optical transceiver that further includes an inline programmable module such as a FPGA.

"FIG. 4 is a diagrammatic illustration of a system in which an SFP optical transceiver located at a network node with an FPGA that is programmed from a remote node.

"FIG. 5 is a diagrammatic illustration of a system similar to that of FIG. 4 in which the FPGA is configured as an embedded traffic generator.

"FIG. 6 is a diagrammatic illustration of a system similar to that of FIG. 4 in which the FPGA is configured to perform intelligent loop back."
