Agere announces 10 Gbit/s surface-mount receivers and MSA
Agere s new receivers can be mounted directly to the surface of a line card without the need to core a hole through the board, saving critical real estate and manufacturing time for systems makers. The devices add to Agere s established portfolio of 2.5 and 10 Gbit/s receivers.
"For the first time, systems manufacturers can implement a standardized, high-performance surface-mount receiver for high-density applications," said Meg Acker, director of marketing for Agere?s Optical Access product line. "These devices offer a compelling balance of performance versus size, power dissipation and price."
Agere s new R194 family of APD and PIN receivers are among the industry s highest performing 10 Gbit/s receivers in a small-form-factor package. The RA194W APD receiver offers -26 dBm sensitivity and -2 dBm overload. APD receivers provide higher sensitivity than PIN-based diodes. Better sensitivity translates to lower demands on the transmission side and longer transmission distances.
Agere s APD receiver is specifically designed for use in ultra-long-haul, long-haul and metro-based multi-channel DWDM and TDM systems.
"The bandwidth profile of our APD receiver makes it perfectly tailored for demanding DWDM applications," said Acker. "Its high sensitivity can also help systems makers save on costs by increasing the distance between amplified spans in an optical network."
Agere s R194T PIN receiver has been optimized with a high gain differential output (6,000 ohms typical) transimpedance amplifier (TIA) with very low power dissipation (0.15 W typical), which allows direct connection to clock and data recovery electronics without the need for a discrete limiting amplifier. The R194T is designed for use in short- and intermediate-reach single-channel TDM applications.
Agere is currently offering sample quantities of the R194T to customers, with samples expected for the RA194W in May 2002. Production quantities for both receivers are expected in the third calendar quarter of 2002.
Receiver multi-source agreement
Agere and Nortel Networks have agreed a common format to establish standards for the new 10 Gbit/s surface-mount receivers. As part of the MSA, which provides common form-factor and electrical and functional characteristics, the companies will independently develop and market respective lines of PIN and APD devices.
The standard specifies product package outlines, pin function definitions, and optical and electrical characteristics for small-form-factor (8 mm x 10.7 mm x 3.3 mm) surface-mount receivers. These receivers can be mounted directly onto a printed circuit board without modifying or cut out space on the board.
Designs will conform to 17-pin butterfly type surface-mount packaging with differential RF output, offering a simplified method for managing RF signals. The initial offering will be 1R-type receivers, which combine a photo-detector and a transimpedance amplifier (preamplifier). The receiver layout specified in the MSA can also accommodate additional integrated features at a later date. Final specifications for the MSA will be made available shortly.
