FREMONT, Calif., December 7, 2010 –Brocade© (NASDAQ: BRCD), Google Inc., JDSU ((NASDAQ: JDSU) and Santur Corporation have announced the formation of a Multi-Source Agreement (the “10X10 MSA”) to establish compatible sources of low-cost, low-power, pluggable 100G optical transceivers based on 10 optical lanes at 10G. The 2km reach goal of the 10X10 MSA bridges the gap between 100m multi-mode and 10km single-mode solutions enabling the roll-out of new networks capable of delivering exponentially higher bandwidth at a significantly lower cost per bit. Unlike 100m multi-mode based on ribbons of fiber, this solution operates on a conventional Single Mode Fiber (SMF) enabling extended reach of 2Km. Compared with other single-mode 100G implementations , this approach does not require 25G electronics such as gearbox ICs to convert 10G data streams to intermediate 25G lanes.
The purpose of the 10X10 MSA is to deliver the industry’s lowest cost 100G solution over 2Km SMF. The 10X10 MSA enables 100G implementation today in modules compliant to the published CFP MSA specifications. Other 10X10 MSA implementations will leverage existing 10G electronics and optics to deliver higher density 100G modules.
Scott Kipp, Brocade standards representative and Chair of the 10X10 MSA, said: “The 10X10 MSA is ready to define a new price and performance trajectory for 100GbE that will significantly accelerate the adoption and economics of 100G deployment. Leveraging 10G technologies helps the 10X10 MSA provide the lowest cost solution in terms of bandwidth per meter and bandwidth per Watt.”
Santur CTO Milind Gokhale said, “The 10X10 MSA is exciting because it provides a roadmap for cost reduction of 100G optical interconnects. Using parallel optics that runs at the same rate as electrical lanes avoids the excess cost and power associated with gearbox devices and brings significant cost relief to 100G equipment.”

Other users and developers who are interested in joining the 10X10 MSA are encouraged to contact MSA members at info@10x10msa.orghttp://www.10x10msa.org/press_releases/10x10MSA_press_release_Final.pdf |

Fremont, CA – July 14, 2010 – The Optical Internetworking Forum (OIF) members have finalized two implementation agreements (IAs) addressing the key electro-mechanical aspects of a 100G long-haul transmission module and control plane logging and auditing. Both of these IAs provide equipment vendors with important tools for bringing products to market.
The OIF 100G Long-Haul DWDM Transmission Module IA provides component and system suppliers with a modular interface approach. Key aspects include; module mechanical dimensions, electrical connector and pin assignment, module hardware signaling pins, high-speed electrical characteristics, power supply, power dissipation, and management interface. “We expect this to be the industry successor for the 300 pin MSA,” said Karl Gass, the OIF’s Physical and Link Layer Working Group vice chair. “This design provides for higher density placement on host line cards with a higher speed data and advanced management interface.”
The OIF Control Plane Logging and Auditing with Syslog IA defines the protocols, record types, data structures, and fields for log files generated by a Network Element (NE). It also addresses controlling and securing the generation, transport, and storage of log data to provide a flexible logging capability for the OIF’s User Network Interface (UNI) and External Network to Network Interface (E-NNI). Version 1.1 of the IA fully conforms to the IETF standards for Syslog and precisely defines a general set of log messages for the OIF's control plane
protocols.
“The ability to log signaling and routing messages as they traverse multiple UNI or E-NNI interfaces adds a useful and effective way to help assure correct and secure operation of the signaling and routing entities,” said Doug Zuckerman, of Telcordia Technologies and the OIF’s OAM&P Working Group chair. “This is an important tool to help carriers deploy and operate control plane technology in their networks.”
Both IAs can be viewed on the OIF’s website at http://www.oiforum.com/public/impagreements.html

Fremont, CA – March 22, 2010 – The Optical Internetworking Forum (OIF) membership has voted to approve an implementation agreement (IA) for the 100G Integrated Polarization Multiplexed (PM) Quadrature Modulated Transmitter. The implementation agreement supports DP-QPSK as a modulation format as specified in the OIF’s 100G Framework Document and also specifies operating rates up to 32GBd. However, the IA strives to remain modulation format and data rate agnostic to maximize applicability to other future applications.
“The transmitter IA is the first project completed from the Framework Document that defines one of the most complex components of the 100G DWDM transmission system,” said Karl Gass of Sandia National Labs and the OIF’s Physical and LInk Layer Working Group vice chair. “The member companies are working together at this early stage in order to accelerate the adoption of 100G technology by defining common building blocks.”
This week at OFC/NFOEC the OIF is hosting a Components Showcase in Booth #3041. The Components Showcase will display components, modules, and/or other hardware supporting the OIF Physical and Link Layer 100G projects focused on Integrated Photonics Transmitters and Receivers, Forward Error Correction, and Transponders. OIF member companies that will be participating include Fujitsu Optical Components, NEC, NeoPhotonics, Opnext, Picometrix,
Sumitomo Osaka Cement, TriQuint Semiconductor, u2t Photonics AG, and Vitesse Semiconductor.
Other 100G projects outlined in the 100G Framework Document include an Integrated Photonics Receiver, a Transponder-Electromechanical MSA and a Forward Error Correction project.

Fremont, CA – November 6, 2009 – A new 100G project has been launched by the Optical Internetworking Forum (OIF) to define a Module Management Interface. The project, started in the Physical and Link Layer Working Group, has set a goal to develop a Management Data Input/Output Interface (MDIO) for the 100G Long Haul DWDM Transmission Module. The MDIO project will specify the logical architecture and frame structure, module control and host-module signaling theory, and MDIO register set. Work on the 100G Long Haul DWDM Transmission Module Multisource Agreement (MSA) began a year ago and the MDIO interface is an important component to completing the project, enabling multi- vendor interoperability.

San Francisco, Calif. – October 20, 2009 — The Fibre Channel Industry Association (FCIA) today announced that the 16GFC development within ANSI INCITS T11.2 Committee is proceeding at an accelerated pace as the FC-PI-5 document is entering the letter ballot process. The ballot process is a major milestone that marks the technical stability and completeness necessary for vendors to commit to silicon on their upcoming designs based upon the FC-PI-5 standard.
With 16GFC, users will experience twice the bandwidth of 8GFC — doubling savings in price/performance, power and port density. Transparently, without user intervention, 16GFC is auto-negotiated backward compatibly to 8GFC and 4GFC, ensuring that the user need not make a forklift remove and replace of their 4GFC or 8GFC Fibre Channel SAN to integrate individual 16GFC products at the pace of their own choosing. 16GFC provides a natural value migration from 8GFC and ensures the end user full confidence that 8GFC purchases made today are preserved investments for tomorrow.

15 October 2009 : A revision to key Optical Transport Network (OTN) standard - Recommendation ITU-T G.709 - extends its applicability to 40 and 100 Gigabit Ethernet (GbE). This revision also adds a variable-size switchable container (ODUflex) to the OTN hierarchy to more efficiently carry packet and constant bit rate clients, which did not fit well into the traditional fixed-size OTN containers. OTN mappings for storage area network (SAN) interfaces and mobile interfaces are also a part of this new revision.
ITU-T Recommendation G.709 "Interfaces for the optical transport network (OTN)" describes a means of communicating data over an optical network. It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems.
Operators are facing challenges with the migration from traditional SDH/SONET to IP/Ethernet based services. The ITU-T G.709 OTN standard is a vehicle to enable convergence, and for providing a common and SONET/SDH-like operational model for network administration, performance monitoring and fault isolation, without altering the individual services.
Using OTN, multiple networks and services such as legacy SONET/SDH, Ethernet, storage protocols and video can all be combined onto a common infrastructure.
Most importantly, unlike SONET/SDH, OTN is the only transport layer in the industry that can carry a full 10/40/100 GbE LAN PHY from IP/Ethernet switches and routers at full bandwidth. With the rapid migration towards IP/Ethernet-based infrastructure, OTN becomes the transport layer of choice for network operators.
