CWDM4 MSA Group to Support Deployment of 2km 100G Links in Datacenters

New Consortium to Define and Promote Industry-Wide Adoption of 100G Interconnect Optical Specifications for 2km Link Distance Over Duplex Single-Mode Fiber

SAN JOSE, CA–(Marketwired – Mar 31, 2014) – The CWDM4 MSA (Coarse Wavelength Division Multiplexed 4x25G Multi-Source Agreement) Group today announced the formation of an industry consortium dedicated to defining specifications and promoting adoption of interoperable 2km 100G interfaces over duplex single-mode fiber (SMF).

To meet modern datacenter expansion requirements, the CWDM4 MSA members will focus on developing a new cost-effective duplex-fiber 100G optical interface to address the 2km link distance.

The CWDM4 MSA participants expect to address industry needs by advancing unique technologies to create a diverse and competitive supply chain, while providing products that are optically compatible.

“The IEEE standardized a cost-effective 100m solution known as ‘SR4’. Beyond 100m, there is only the ‘LR4’ standard, which is targeted to achieve 10km. Customers, particularly hyperscale data centers, are looking for solutions up to 2km,” remarked Dale Murray, principal analyst, LightCounting Market Research. “The industry is now coming together, through this MSA, to provide a cost-effective data center reach of 2km. This solution will smooth the process of getting to 100Gb Ethernet.”

Members of the CWDM4 MSA include Avago Technologies, Finisar Corporation, JDSU and Oclaro, Inc. Requests for additional information, queries and interviews may be submitted at www.cwdm4-msa.org.

Vitesse Delivers Turnkey Solution For Industrial IoT Networking

Vitesse Semiconductor Corporation (Nasdaq: VTSS), a leading provider of advanced IC solutions for Carrier, Enterprise and Internet of Things (IoT) networks introduced the latest generation of its SparX-III™ Ethernet switches – VSC7420-04, VSC7421-04 and VSC7422-04 – optimized for industrial IoT applications, including building automation, manufacturing automation, intelligent transportation, smart energy, and video surveillance/security. Leveraging Vitesse’s newest SparX-III family, turnkey Ethernet hardware and software reference system and ODM model enables nearly 70% faster time-to-market over traditional methods.

“We see industrial IoT networks standardizing on Ethernet, which introduces a host of new requirements including low power, security and stringent reliability,” said Andy Ebert, senior product marketing manager at Vitesse. “OEM design and development costs typically skyrocket due to the variety of industrial systems and applications they must support. Vitesse offers a way to serve highly-diverse IoT market needs with a finite set of hardware and software solutions, generating significant OEM savings in development, inventory and certification costs.”

 

Next-Generation Ethernet Switches Aligned With IoT Networking Demands

Vitesse’s latest SparX-III Ethernet switches support a variety of port counts, combinations of multiple interfaces, and advanced feature sets either using a single device, or a combination of multiple devices with compatible footprints. SparX-III family features include:

– Energy Efficiency: Featuring Vitesse’s EcoEthernet™ 2.0, the SparX-III Ethernet switches, combined with the industry’s only 12-port i-temp PHY – VSC8522 – enable a broad range of energy efficient Gigabit Ethernet platforms, ranging from single chip, 10-port to 2-chip, 24-port count solutions;

– Rugged I-Temp Support: Vitesse’s SparX-III Ethernet switch family is available with i-temp support, readily meeting systems requirements for rugged industrial and outdoor environments;

– Unmanaged to Lightly Managed Intelligence: For optimal network control and delivery of differentiated services, Vitesse’s SparX-III Ethernet switches deliver basic VLAN, Q-in-Q, Quality of Service (QoS) and rate limiting processing.

 

Sampling now, the family includes:

 

VSC7420-04:  10-Port Layer-2 Gigabit Ethernet switch with eight fully integrated copper PHYs

 

VSC7421-04:  17-Port Layer-2 Gigabit Ethernet switch with 12 fully integrated copper
PHYs; and

 

VSC7422-04:  25-Port Layer-2 Gigabit Ethernet switch with 12 fully integrated copper PHYs
