Pulse Introduces 10GBASE-T Ethernet Connector Modules
Multi-gigabit Ethernet technology and adoption are rapidly moving forward.
Crehan Research in May said 25GbE customer adoption has seen a much stronger start than either 10GbE or 40GbE. 25GbE shipments surpassed 200,000 ports in just over a year, according to the firm, which noted that it took 10GbE six years to hit that mark.
And in July of 2016 Crehan Research said that the cost of bandwidth on these systems is getting far more affordable for those who deploy them. The dollar-per-gigabit cost of server-class Ethernet networking bandwidth will fall to less than one-fifth its current level within five years, according to Crehan. The corresponding bandwidth deployed will increase more than seven-fold in that period, it said. That, it added, will enable the next phase of cloud services.
“Over the past five years, server-class Ethernet networking bandwidth has seen a robust increase of about 30 percent per year, in conjunction with ever-increasing data center network traffic and an annual dollar-per-gigabit price decline in the 10 to 15 percent range,” said Seamus Crehan, president of Crehan Research. “With the arrival of 25 gigabit Ethernet, 50GbE and 100GbE, we expect an inflection change in this trend, with total bandwidth increasing close to 50 percent annually and the cost-per-gigabit of that bandwidth declining by close to 30 percent annually.”
He added that there are already examples in which 25GbE, 50GbE and 100GbE data center Ethernet products have small, and sometimes no, price premium over comparable lower speed offerings. Nonetheless, Crehan said, 10GbE should remain a key server-class Ethernet networking technology through 2020, especially in enterprise data centers.
“Although there is a lot of excitement around 25GbE, 50GbE and 100GbE, and justifiably so,” Crehan said, “many enterprise data centers are still using 1GbE for server networking attach. A lot of these customers will likely see 10GbE, and especially 10GBASE-T, as their next network upgrade path.”
(According to the Ethernet Alliance, 10GBASE-T has been available via add-in server cards since 2008. But 10GBASE-T became more widely available about five years ago, as LAN on Motherboard or configurable daughter cards become available.)
Speaking of 10GBASE-T, Pulse Electronics Networking BU this month introduced the JT8 series. This is a family of 1x2 and 1x4 10GBASE-T Ethernet Connector Modules.
These modules are for routers, servers, switches, video displays, and gateway applications that require increased bandwidth. Pulse said they’re ideal for designers who need to reduce the height of their products, because they allow a portion of the part to sit below the PCB.
The JT8 series, which is now in volume production, offers the options of four and five channel magnetics, and comes with or without light pipes. These products are
802.3an compliant, halogen free, and RoHS 6/6 capable.
