Siemon Launches Passive Copper Cabling Assemblies

By Jai C.S., TMCnet Contributor

Siemon (News - Alert), a manufacturer of IT network cabling and infrastructure systems, has launched their high-speed, low latency 40+Gb/s SFF-8470 4X Passive Copper cabling products.
These newly launched copper cable assemblies, as stated, are designed to support high-speed interconnect applications such as high-performance computing, or “HPC,” enterprise networking and network storage systems. Moreover, the SFF-8470 products are capable of supporting data transfer rates from 2.5Gb/s to 10+ Gb/s per lane.
Siemon’s 8470 cable assemblies comes with a shielded wafer construction where the signal conductors are directly attached to the connector's contacts eliminating a printed circuit board and enhancing noise resistance to maximize signal integrity. The twin-axial shielded cable conductors are reportedly laser welded which contributes to reduction in cross-talk and jitter to support 10+Gb/s data rates. SFF-8470 die cast back shells and latches are interoperable with all compliant interfaces.
“Siemon's SFF 8470 supports the second generation of the Shielded Multi-Lane SFF-8470 copper cabling standard with data rates through 10+Gb/s per lane for IO interface applications” said Ed Cady, business development manager for Siemon Interconnect Solutions division.
“This IO connector interface has had wide standards and value-added interface link design-ins,” Cady added.
The 8470 product supports a wide array of data protocols/interfaces, including InfiniBand SDR, DDR and QDR; Ethernet 10GBaseCX4, 40GBaseCR4. These cables also support FibreChannel, RapidIO (News - Alert), Myrinet, SAS, SATA, Aurora, VITA VXS and XAUI/XAUI-2 IO interface links as well as SONET/SDH.
Siemon official also clarified that the newly announced product is available in 24 to 30 wire gauges and various assembly lengths for specific applications.
Established in 1903, Siemon has been focused in the development and manufacture of high quality, high-performance network cabling solutions. Siemon’s Interconnect Solutions business unit specializes in the development of high-speed interconnects. Siemon offers a comprehensive suite of copper and optical fiber cabling systems.
