JDSU touts tunable SFP+ optical transceiver module
Having been first to market with a tunable XFP, JDSU (NASDAQ: JDSU) (TSX: JDU) says it has developed a tunable SFP+ optical transceiver module that will also be the first such device out of the gate. The module, which JDSU says is being demonstrated to customers, leverages the same Integrated Laser Mach-Zehnder (ILMZ) chip as the tunable XFP to provide full C-Band tunability. JDSU expects it to be in production within the next 12 months.As with other tunable devices, the tunable SFP+ transceivers will replace fixed-wavelength optical transceiver modules, particularly in enterprise and metro network equipment, JDSU says. The advent of tunable SFP+ modules will provide flexible wavelength provisioning and lower inventory requirements, the company adds. For example, the device will support remote configurability and 50-GHz channel spacing.In addition to replacing fixed SFP+ optical transceiver modules, JDSU also anticipates that equipment designers will adopt them in place of X2 and XENPAK transceivers."The invention of the tunable SFP+ transceiver is the latest example of how JDSU's focus on R&D and vertical integration has translated into innovative and compelling new products," said Alan Lowe, president of the CCOP segment at JDSU. "We're very excited by initial feedback from customers who have told us that the tunable SFP+ transceiver will help them more efficiently manage their enterprise and metro networks."

Dallas Semiconductor launches 20-kilohm option for its SFP optical control/monitor
Similar to the current DS1859-050 (50-kilohm full-scale resistance option), the DS1859-020 controls laser-driver bias and modulation currents, while also managing system monitoring functions required for SFF-8472-compliant optical transceivers. The new 20-kilohm resistance option provides higher adjustment resolution, which is optimal for calibrating some laser drivers, explain company representatives.The DS1859's high level of integration reduces component count and layout area and speeds up the design of optical transceivers. Control functionality is comprised of two 256-position, nonvolatile (NV) variable resistors with customer-programmed, temperature-indexed EEPROM lookup tables.An integrated 12-bit analog-to-digital converter (ADC), temperature sensor, and MSA-compliant register and memory architecture provide SFF-8472 diagnostics monitoring functionality. The device monitors three external analog signals, as well as Vcc and temperature. Programmable alarm and warning trip points for all monitored signals alert the system to out-of-tolerance conditions. Additional features include internal calibration and ADC ranging to increase the dynamic range for received optical power measurement. Communication with the devices is achieved over a 2-wire serial interface.The DS1859 is available in a 4 x 4 BGA package (0.8-mm pitch) or 16-pin TSSOP. It operates from a 2.7-V to 5.5-V power supply over a -40 ° Celsius to +95 ° Celsius temperature range. An evaluation kit is available.

Tektronix offers SFP+ automated test and debug via DP0/DSA/MSO70000 Series oscilloscopes
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: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."
