With an additional row of contacts, the QSFP-DD provides an eight lane electrical interface.
Molex drives development of next- gen network technologies
Molex is serving in several leadership roles in Multi- Source Agreement (MSA) Groups aimed at fostering development of new high-speed, high-density interfaces and links used in telecommunication, data centre equipment and networking platforms. The company is a founding promoter, editor and member of the QSFP-DD (Quad Small Form Factor Double Density) MSA, the SFP-DD MSA, and the 100G Lambda MSA groups, all of which support multi-vendor interoperability. Towards the end of 2017, the QSFP-DD MSA released an updated 3.0 hardware specification for the new QSFP-DD form factor. A QSFP28 compatible double-density interface, QSFP-DD pluggable modules can support up to 400 Sckipio’s G.fast silicon delivers gigabit broadband Sckipio’s newest G.fast broadband chipset family delivers 1.2 gigabits of aggregate bandwidth over 100mof telephone wire. The start-up’s SCK-23000 chipset family implements the ITU’s G.fast Amendment 3 212a profile. The new profile doubles the spectrum used from 106MHz to 212MHz, boosting the broadband rates. “What the telcos want is gigabit services,” said Michael Weissman, vice president of marketing, “This second- generation [chipset family] allows that.”
Systems designed for
Gbps in aggregate over an 8 x 50 Gbps electrical interface (quadruple the bandwidth of conventional QSFP modules), allowing networking equipment to keep pace with advances in ASIC (application- specific integrated circuit) technology. “Building and sustaining the pipeline of interoperable interconnect solutions is absolutely critical to support advances in transceiver modules, switch technologies and servers. Through strategic collaborations, we can provide the expertise needed within the industry to continue pushing the boundaries of high-speed, high-density networking,” said Scott Sommers, group product manager at Molex, co-chair of the QSFP-DD MSA and chair of the SFP-DD MSA. The SCK-23000 comprises two chipsets. One is the 8-port DP23000 chipset used at the distribution point unit (DPU) while the second chipset is the CP23000, used for customer premise equipment. The chipsets enable an aggregate line-rate performance (downstream and upstream) of 1.7Gbit/s over 50m, to 0.4Gbit/s over 300m. The DP23000 chipset also supports two bonded telephone lines, effectively doubling the line rate. Implementing G.fast requires vectoring, an intensive digital signal processing task used to rejects crosstalk – leaking signals – between the telephone wires at the distribution point. Sckipio says the SCK- 23000 supports up to 96 ports (or 48 bonded ports) at the 212a profile. The design uses distributed parallel processing that spreads the vectoring computation among the DP23000 8-port devices used.
management up to 3.5W optical modules, the new interface features two lanes that operate at up to 56 Gbps per lane, providing throughput of 116 Gbps over the two lanes with PAM4 modulation. By doubling the lane density and data rate of an SFP connector, the SFP-DD interface will significantly boost port density and deliver optimal scalability in networking cables and equipment. Molex and other industry leaders recently established the 100G Lambda MSA to develop specifications based on 100 Gbps per wavelength optical technology, and addressing the technical challenges of achieving optical interface interoperability for transceivers produced by different manufacturers. low-latency capabilities of the solution make it the clear choice for operators seeking an affordable and sustainable 5G rollout, specifically in those instances where backhaul fibre is initially unavailable or impractical,” said Hossam Salib, VP, cable & wireless strategy. Adtran’s Mosaic Open Network Alliance was established in August, 2017, to accelerate the industry’s transition to open programmable, scalable networks and to provide operators from across the globe with a single point of reference for leading SD- Access and NFV solutions. “We see this open network alliance as driving value for customers around the world by bringing together the global technology leaders for both fixed and wireless access and backhaul
QSFP-DD modules will be backwards compatible with existing 28 Gbps QSFP and QSFP+ form factors and provide flexibility for end users, network platform designers and integrators. Providing excellent signal integrity and thermal protection, Molex QSFP and QSFP+ Integrated Product Solutions support Ethernet, The SFP-DD MSA recently released the initial hardware specification and drawings for the SFP-DD electrical interface. The SFP-DD specification builds on a full range of Molex SFP+ and SFP Interconnect Solutions, including cages, connectors and cable assemblies, and optical modules. Targeting support for thermal Fibre Channel, SAS and InfiniBand applications. Adtran has announced an agreement with CCS to deliver self-organising mmWave technology for backhaul and access capabilities to wired and wireless operators as they embrace 5G densification architectures and significantly higher access speeds. The global agreement with CCS, a UK-based pioneer in self-organizing 5G mmWave backhaul and Gigabit access, forms the latest development in Adtran’s Mosaic Open Network Alliance initiative. It complements the firm’s existing SD-Access based NG-PON2 solution for 5G backhaul, featuring non-service impacting wavelength agility and ultra- low latency to safeguard the extraordinary SLA performance demands of 5G, IoT and other mission-critical services. “The resiliency, scale and
