http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productID=2795 Silicon Photodiodes With Built in Preamplifier * Available in Standard TO-5 and TO-8 Packages * Low Noise * High Sensitivity

These detectors consist of a silicon photodiode and a preamplifier chip integrated in the same package. The standardized packages allow for easy integration into optical systems. Both High Speed and High Gain detectors are highly sensitive over a wide spectral range. The close proximity of amplifier and detector minimizes stray capacitances, increases response speed and eliminates external noise pickup. High Speed detector applications include optical fiber communication, video signal transmission and optical disk pick up. The High Gain detectors can be used in low-light level applications such as analytical and measurement equipment. A variable gain can be achieved on the High Gain detectors by externally connecting a resistor in parallel with the built-in 1GO feedback resistor. These detectors are compatible with our C-Mount photodiode mounts. A power supply is required to operate the detectors.

http://www.pointless.net/pipermail/ronja/2005-September/007454.html I have a prototype PCB for a 100MHz RX/TX unit but simply have had no time to test/tweak/enhance it. LED fall time is the issue so far; I know what to do about it, but (payed) work takes precedence over a GPLed project.

> > [just finished a 5ns IR pulse detector with associated 25W pulse >> laser driver for Work, looking into using a similar design for a >>  50..100Mbit/s Open Hardware optical link] > >That sounds great.

The work project was fun. The design can send and receive pulses over several hundred meters without any lenses. Of course, this uses the abovementioned 25W pulse laser ;-) Driving that one was...interesting, seeing that I needed to switch 30Amps with edge rates of a few nanoseconds. Inductance really sucks.

>Tell us more about it.

I intend to use the optical link for a local volunteer mesh-networking project. The plan is to have it rate-limited by the SNR of the link. Rough sketch:

* Tx: 100Base-T->PHY->FIFO->FEC->Luxeon/laser * Rx: PIN->Cascode amp->Detector->Sync/FEC->FIFO->PHY->100Base-T * Tx: 100Base-T->PHY->FIFO-> http://en.wikipedia.org/wiki/Forward_error_correction ->Luxeon/laser (TransimpedenceAmp) * Rx: PIN->Cascode amp->Detector->Sync/ http://en.wikipedia.org/wiki/Forward_error_correction ->FIFO->PHY->100Base-T

The FEC is an error correcting block code implemented in a CPLD and a ROM. This FEC is also responsible for creating state transitions on the link (to avoid baseline wander). The SNR determines the transmission of the FEC. EthernetTransceiver implements all this in a single IC commercially available from many vendors.

Target is to have all components SMD, but as solderable as possible (ie no BGA or finer pitch than necessary), and available from international distributors such as DigiKey. Schematics and PCB will be available as PS/PDF/Gerber, and ABEL/VHDL for the CPLD. I won't be using gschem/PCB, as I described in the other thread, sorry (although if I have enough time I may redo the schematics in gschem). As with all volunteer projects, this may take a while to materialize. Work is especially busy nowadays, so don't hold your breath.

> > first is you would have to change the encoding of the MLT3 signal to 2-level signal which is suited for optical transmission. in easiest case manchester code.

I have discovered a bi-level DC-nulled modulation that has better efficiency than the formerly patented IBM 8B10B - http://en.wikipedia.org/wiki/8b/10b_encoding, which has only 80%. Namely 90% exactly. And doesn't have excessive requirements on the codec. Maximum run length of identical bits is 10 bits. That means 1Gbps optical Ethernet could be upgraded to 1.125Gbps probably without a change in the PHY or Ronja Manchester 10Mbps could be upgraded to 18Mbps without a change in the PHY. The same for all the other numerous technologies that use 8B10B, see the Wikipedia article on 8B10B. Does anything like this already exist? If not, I could try to make a contract with someonethat he can patent it, sell the patent to proprietary designs only, give irrevocable rights to all open source designs, and pay a fulltime salary to me for the rest of my life. Then I could go developing Ronja :) Otherwise I can write an implementation and publish it to constitute a prior art which makes sure it's unpatentable ;-)

SFH 495 as alternate IR transmitter? ent there looking for the Hsdl-4230. By the way Clock advised me that it might be a laser and will require a different drive circuit, any idea, how we might proceed with that.... and i wasn't able to find any safety Class specification of this led in the datasheet... anybody know how we might do that?

I'd like your opinion about the possibility of using a SFH 495 IR diode. http://pdf1.alldatasheet.com/datasheet-pdf/view/45680/SIEMENS/SFH495P.html It has a rise time of 7ns and a half angle of 30 degrees at 2.1 volts. Please let me know if this may be used as an alternate to HSDL-4230.

Sounds like it's yet another OpenRRCP compatible switch ASIC, and there's plenty of those around: http://openrrcp.org.ru/hardware

I'm wary of RRCP -- it seems that it's completely disabled on most new hardware, and even when it hasn't been fused out, soldering pullups to TQFP packages is a pain in the behind.

For more practical FSO-ISP use, needing another external microcontroller to do RRCP to SNMP in such a design, (for it *is* the standard), is also a pain in the behind, leaving aside the consideration of the time cost for writing software to do that.

Anyway, to get back to what clock said.

This is a store-and-forward switch ASIC. Realtek sheets state clearly the bandwidth throttling uses 802.3x flow control as its throttling mechanism rather than early drop.

802.3x PAUSE should "just work" over a RONJA link, but of course it assumes the guys at the other end of the link are in your Ethernet broadcast domain -- which might be too much network intimacy for some individuals.,

I believe this capability however is independent of its ability to generate 10MHz link beat, which is what RONJA requires, and this is what clock was getting at.
