Receiver optimises optical transceiver
design
A new receiver optical subassembly is intended for small form factor transceivers and transponders such as XFP, X2 and Xenpak.
Meeting the demand for high performance, low cost optical components, Northlight Optronics' APD receiver optical subassembly (ROSA) is intended for small form factor transceivers and transponders such as XFP, X2 and Xenpak The high performance APD ROSA offers OEMs a product whose price/performance ratio is not achieved by any other noncaptive subcomponent vendor

Some optical transmitters like it hot
Intended for use in small form factor optical transceivers, Northlight Optronics' TOSA is a high operating temperature 10Gbit/s transmitter optical subassembly for 40 and 80km applications.
Transmitter aims to boost DWDM transceivers
Suitable for use in long and extended reach applications, the PGT20310 is a cooled transmitter optical subassembly for use in 2.5Gbit/s modulated DWDM compatible transceivers.
Extending and strengthening its 10Gbit/s product offering, the APD ROSA module incorporates Northlight Optronics' proprietary InGaAs avalanche photodiode (APD) with a low noise transimpedance preamplifier (TIA).
Housed in a small diameter coaxial package, the receiver is designed to convert optical signals to electrical signals with high sensitivity and with excellent overload characteristics.
The receiver allows simplified integration into small form factor XFP and other transponders and receivers and will also be very attractive to OEMs aiming to reduce the production costs of existing PCB designs.
Application areas include 10Gbit/s SDH/STM-64 long haul systems, 10Gbit/s Sonet OC-192 long reach equipment, and 10Gigabit Ethernet applications.
The APD ROSA is available with an LC or SC receptacle, alternatively a fibre-tail, with designated product numbers being PGR20410, PGR20418 and PGR20419, respectively.
All receiver options guarantee an optical return loss of better than 27dB.
The ROSA's differential electrical output can be interfaced to a printed circuit board using traditional leads or with an optional flex foil.
Simplifying heat dissipation management, power consumption for the receiver is just 0.15W at 3.3V.
Making it easy to interface with a PCB with low crosstalk, the receiver offers a differential coplanar output with high, 9000V/A gain.
The ROSA features high, -24dBm EOL sensitivity and a -5dBm EOL overload figure.
These characteristics facilitate ease of design with good margins.
Northlight Optronics' coaxial 10G APD ROSA is a high performance product not yet available from any other manufacturer on the open market.
Northlight is exhibiting at ECOC 2004 in Stockholm, Sweden where this product can be seen on Stand 103.
