New 100 Gb/s Driver is 1st to Combine Two Channels with Bias-Tees and State of the Art Channel-to-Channel Isolation

first_imgTriQuint Semiconductor Inc. has introduced the industry’s first dual-channel, surface-mount optical modulator driver that reduces bills of materials and shrinks PCB areas dedicated to optical driver functions. The new TGA4947-SL is released in conjunction with the European Conference on Optical Communications (ECOC) in Amsterdam, The Netherlands. TriQuint’s TGA4947-SL is designed for 40 Gb/s and 100 Gb/s light wave networks using DQPSK and DP-QPSK modulations, respectively. It combines two driver amplifier channels and bias-tees in a compact surface-mount (SMT) package that maintains high channel-to-channel isolation of 30dB from DC to 40 GHz. The excellent isolation provided by TriQuint’s solution is essential to reduce bit error rate impact to maintain channel performance. TriQuint’s new modulator driver offers the lowest power dissipation available, making it a ‘green’ solution that dissipates half the power of competing products (just 1.2W per channel at 6Vpp output.) The TGA4947-SL also enables a more compact optical transmitter design, a key requirement of 100 Gb/s Optical Internetworking Forum (OIF) MSA standards. It enables economical surface mount assembly processes and eliminates the need for costly connectorized driver “Bricks” while enabling SMT multiplexer (MUX) modules. The new TGA4947-SL modulator driver is compatible with TriQuint’s Smart Evaluation Board (Smart EVB™) solution for simplified RF connectivity. Smart EVB’s reduce by an order of magnitude the time required to set up and operate these devices in standard RF test and optical test stations. The new TriQuint TGA4947-SL is designed to drive Mach-Zehnder modulators in optical transceivers and transponders serving metro and long-haul networks. Carriers are rapidly increasing the data rates of these networks to accommodate exponential traffic growth driven by the demand for broadband connectivity.  By combining two channels along with accompanying bias-tees in a single surface-mount package, the TGA4947-SL addresses the need to reduce network component costs through lower part counts and maintaining superior electrical characteristics. Samples and evaluation boards are available for the TGA4947-SL. Contact TriQuint for product details.last_img read more

Two Man Utd Players Shut Out By Injury As Tottenham Hotspur Clash Draws Near

first_imgManchester United will be missing the presence of two defenders ahead of their encounter against Tottenham Hotspur on Friday night.Coach Ole Gunnar Solskjaer revealed Alex Tuanzebe and Phil Jones weren’t fit enough to face Jose Mourinho’s men at the Tottenham Hotspur Stadium. “Yeah we have got a couple of injuries,” Solskjaer was quoted by Man United’s official website as saying.“Axel will probably be missing, and Phil Jones will be missing [Man United’s clash against Tottenham]. Apart from that, I would say everyone else is available for selection.”He added: “During Pre-season you want to give everyone a chance, everyone the same opportunity to stake a claim for the team.“Everyone will play a part, and we have got plenty of games.“Hopefully, we have got a few cup games, plus the league games and hopefully the Europa League, so we will be going into August sometime.”United will be hosted by their former manager Mourinho in their first game of project restart by 8:15pm.The Red Devils are bidding for a Champions League spot and are three points behind fourth-placed Chelsea.Mourinho’s Hotspur are 8th on the log, four points far from United.Relatedlast_img read more
