Plug and play system Infrastructure specialist Siemon has expanded its LightHouse ® advanced fiber cabling solutions with a comprehensive Base 8 plug and play system of fiber enclosures, modules, adapters, assemblies and jumpers. Current 40Gb (40GBASE-SR4) and 100Gb (100GBASE-SR4) per second multimode fiber applications, deployed for backbone switch-to-switch links in the data center, are based on eight optical fibers with four fibers transmitting and four receiving at either 10Gb or 25Gb per second. When using 12-fiber MPO/MTP solutions for these 8-fiber applications, 33 percent of the optical fiber is unused.While conversion cords or modules can be used to enable 100 percent fiber utilization, these solutions add cost and complexity, and increase insertion loss. Siemon’s new Base 8 system is designed to enable 100 percent fiber utilization, eliminating the need for conversion cords or modules while providing a complete end-to-end Base 8 fiber system to support current and future eight-fiber applications. “With current and future fiber applications all dominated by fiber counts that are divisible by two or eight fibers, including 200 and 400Gb per second over multimode and singlemode that are currently in development, using a Base 8 plug and play system offers the simplest, most efficient migration to advanced fiber speeds in the data center,” said Alberto Zucchinali, EMEA data center solutions and services manager for Siemon.

Cables for testing times Pasternack has released four new 1mm flexible cables, operating up to 110GHz, designed to deliver precision results for vector network analyzer (VNA), semiconductor probe, automotive radar and military radar testing. The cables are suitable for applications such as test benches, radar, microwave radio and millimeter wave radio. Pasternack’s new VNA test cables deliver precise results using a coaxial cable and 1mm stainless steel connector interfaces. The coaxial test cable is covered by a non- conductive Nomex ® outer sleeve. This light armoring protects the 0.27 inch diameter cable and improves stability during flexure. The cables feature 50 Ohm impedance, a maximum VSWR of 1.5:1 and excellent phase/amplitude stability under flexure.

The cables will operate over a temperature range from –65°C to +125°C. The vector network analyzer cables are RoHS and REACH compliant, plus the cable assembly is fully tested and comes with serialized test data. The cables are available in standard 6 and 12 inch lengths with male-to-male or male-to-female configurations.
