Bookham Technology has released the first of a series of 10Gbit/sproducts. The initial product is an ASOC-based compact 10Gbit/smini-FLAT receiver for metro and very short reach (VSR)applications. The product has been designed to be easilyintegrated into SONET/SDH systems at OC-192 or STM-64 datarates.To allow the use of high-speed coplanar electrical waveguides,the product has been designed in a mini-FLAT package withsurface-mounting connections.
This helps to reduce the cost ofassembly into customers' systems.
The new mini-FLAT receiverincludes a high-speed InGaAs PIN photodiode and an internaltransimpedance amplifier with differential outputs, providingimproved noise performance and higher sensitivity.
Thisconfiguration reduces the number of components needed wheninterfacing with limiting amplifiers and clock and data recovery(CDR) circuitry and therefore offers further systems cost andspace savings.
The product has external photodiode biasconnection, to allow additional functionality, such as theimplementation of a receive average power monitor function.
Thereceiver requires a single 5V supply voltage.
This furthersimplifies system board configuration, which is aimed at totalsolution cost reduction.
The initial product will offer a typicalsensitivity of -13dBm, making it suitable for 600m VSRconnections.
A next generation product, aimed at short-haul andintermediate-reach SONET/SDH requirements, will be introducedlater in the year.
The product, housed in an uncooled 8-pinmini-FLAT package with a single-mode fibre pigtail, is alreadysampling to selected customers.
Because the receiver is based ona fully Telcordia qualified product already in volume production,the 2.5Gbit/s mini-DIL receiver, Bookham Technology will be in aposition to introduce high-volume production in the fourthquarter 2001.
