google for PIN, TIA ROSA , (receiver optical sub assembly). Data Communications – Gennum offers a comprehensive suite of backplane interconnect and optical transceiver ICs including laser drivers, equalizers, SerDes, receive optical sub-assemblies(ROSA), clock and data recovery (CDRs), and transimpedance amplifiers (TIAs) for high-speed data communication and telecommunication applications. This group of products is driven by increasing bandwidth demand for video over the Internet supported by optical communications.

The MAX3658 is a transimpedance preamplifier for receivers operating up to 622Mbps. Low noise, high gain, and low power dissipation make it ideal for fiber access and small form-factor transceivers.
The MAX3658 features 45nA input-referred noise, 18kΩ transimpedance gain, 580MHz bandwidth, and 2mAP-P input overload. Operating from a +3.3V supply, the MAX3658 consumes only 66mW. An integrated filter resistor provides positive bias for the photodiode. These features, combined with a small die size, allow easy assembly into a TO-46 header with a photodiode. The MAX3658 also includes an average photocurrent monitor.
The MAX3658 has typical optical sensitivity of -33dBm (0.9A/W), which exceeds the class-B APON requirements. Typical optical overload is 1dBm. The MAX3658 is available in die form with both output polarities (MAX3658A and MAX3658B). The MAX3658A is also available in a 3mm x 3mm 8-pin TDFN package.
An evaluation kit is available: MAX3658AEVKIT ,interfaces with MAX3748 post amplification stage for PECL. The amplifier accepts a wide range of input voltages and provides constant-level current-mode logic (CML) output voltages with controlled edge speeds.

Do you mean fiberoptic? There are tons of packaged pin-tia modules
around, as pcb mountable components. Nearly all have agc amps and
differential outputs, so they could be ac coupled into an fpga's lvds
input. The agc requires that the data stream be balanced, nrzi or
manchester or something, which can be annoying.
If all that makes sense, I can get you some names. Any choice of fiber connector? If you need DC coupling, you usually have to start with a pin diode and condition it yourself.

You didn't answer so many of the questions I asked which would help the 
casual reader on these six newsgroups figure out what your needs are.
Any posts I make in the future will only be to sci.optics.fiber since you 
didn't state which newsgroup you frequent.
In my first attempt to find the module I researched about 4 years ago for a 
free-space optical connection, I found something interesting though I don't 
know the prices:

For 4 Mb/s class (like that module) there are also IRDA modules like 
Vishay's devices that hit 1, 4, and 16 Mb/s that are well beyond the 
original 115 kb/s IRDA spec
http://www.vishay.com/ir-transceivers/
If you want plastic fiber optics with consumer production, the TOSLINK is 
probably a good way to go. The wikipedia.org page brought up a nice Toshiba 
catalog covering up through 15 Mb/s at first glance here
http://www.toshiba.com/taec/components/ProdLineGuide/toslink.pdf
If you want gigahertz class, you're talking much greater cost. I'm 
interested in seeing the $25 item another poster mentioned as well, though 
that's still out of my price range.
If you go to my original post and look at all the questions, you might get 
better responses.
155MBPS can be had for around ten bucks. Not sure how avaible those are 
these days: http://www.optekinc.com/pdf/opf2408.pdf

Optek's receivers seem fine, but their VCSEL lasers suck, but they
change them often enough that they at least suck in different ways.
Tons of people make the pin-tia receivers. We're using the Luxnet
parts just now, mostly based on their agc time-shift behavior. Google

Yes, pretty impresive line-up:

I already asked them for a quotation but... no reply. The free space setup 
is no "must" but would be the best suited for my application. Do you know 
about any other modules which are similar to those I mentioned? Are there 
any comparable modules for fiber apllications?
To sum up my requirements in detail:
- 850nm photodiode
- integrated transimpedance amplifier
- mountable on a PCB
- data rates > 1 Mbs < 1 Gbps
- dfferential LVDS, PECL or CML output (digital)
Looking forward to your replies.... :-)

ST connectors are dirt-common... simple bayonets, and you can buy
multimode jumper cables anywhere.
