Gigalight unveils 3G video SFP transceivers /Tektronix offers SFP+ automated test and debug via DP0/DSA/MSO70000 Series oscilloscopes

Gigalight has introduced its 3G Video SFP optical transceiver modules for SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps) applications. The modules are designed for long-distance and HD video signal transfer, and come in four models: transmitters, receivers, transceivers, and transmitter/receiver. The modules will support transmission distances ranging from 10 km to 80 km. Compared to traditional modules, the 3G video SFPs better overcome transmission impairments to provide long reach at full bandwidth, the company asserts. Gigalight’s 3G video SFP uses MCU control and high accuracy DDM to meets the such specifications as SMPTE 424M, 292M, 259M-C, 297, etc. The new 3G video SFP is Gigalight’s first offering in the video optical communication field. Tektronix Inc. has introduced what it asserts is the first comprehensive automated test and debug offering for SFF-8431, SFP+ PHY, and SFP+ Direct Attach Cable Specifications "10GSFP+CU" Measurements. The new TEKEXP SFP-TX option for Tektronix’s DPO/DSA/MSO70000 Series oscilloscopes are designed to help users easily select measurements for SFF-8431 SFP+ testing and perform all measurements with a single button click. All masks, limits, and measurement parameters are automatically configured, says Tektronix. Users also can change selected measurements and measurement configurations using a new standard-specific user interface. The automated measurements are designed to help engineers efficiently meet SFP+ compliance requirements and generate detailed reports. Users also can change test limits for advanced margin and performance testing, according to Tektronix. Tektronix also has added six new measurements: VMA Rise Time Tx-Qsq DDPWS Fall Time Uncorrelated Jitter (UJ). Setup files are provided based on different signal types such as 8180, PRBS9, and PRBS 31. Signal-specific setup files enable users to perform measurements on different signal types or go into analysis and debug mode, Tektronix says. "The dramatic growth in bandwidth requirements and the increasing worldwide use of high-performance servers is leading to an expanding need for 10-Gigabit Ethernet and in turn new connectivity options based on SFP+," said Roy Siegel, general manager, oscilloscopes, Tektronix. "By offering the industry's first automated and debug solution for validating SFF-8431 SFP+ devices, Tektronix helps make it easier for companies to bring new and innovative SFP+ offerings to market with assurance their products will conform to specifications and deliver optimum performance and reliability." SFP-TX is available for download now from www.tektronix.com and is designed to run on Tektronix DPO/DSA/MSO oscilloscopes with 16-GHz bandwidth and above.
