I think I know what seller you bought that from...
I was waiting for someone else who had this gem on his watchlist
I had a go on Ebay for at least five sellers of a CMA5000 and texted them about two weeks ago. No answer so far
To be honest, I expected this as these units are sold by resellers who have no interest in fixing another unit.
The cheapest one available for me is 700$ with smashed Screen. This is to much for a gamble on running drives.
I found this driver database online with an offline version available :
https://driverpack.io/deMaybe someon has experiences with this provider. Seems more legit to me than a trusty driver from driver.ru
As far as I can see
https://driver-magician.de.uptodown.com/windows only provides backups and restore options.
I tried to search for a PCI9030 driver and most of the offers are installers or at least ransomware.
I found something like this:

I have attetched some pictures of the backplane connecting the modules to the main-unit (1 and 2). Additionally you can see the front of the main unit with removed bezel to get access to the LCD. This is just amazingly well engineered to replace broken screens within minutes. Behind the LCD you can see different ICs:
Spartan XC2S50 As this is a Spartan II I don't believe it is the missing device.
PCI1225 is present on the main unit and the backplane. Seems to be an PCI to PC-Card adapter.
The last pictures are taken fom the insides of the OSA module. You can see the mechanical optical filter on the left. The connector on the right is the input and connects a short patch cable to the external input. Below there are some optical components in a milled tray. Right below there is the first digital board connencting to the optical components. There is an option for the OSA available with a optical drop functionality. Therefore you can see another mountting point for a second connector and an unpopulated optical switch on the optical pcb. Maybe I will add this functionality when the unit is running again.
On the optical PCB there is a LUMINEMT MRED14CXXXX LD
https://www.datasheetarchive.com/MRED14C5003-1-datasheet.html. My best guess would be some kind of alignment of the filter. On the optical PCB there is an optical isolator and a bragg filter, maybe to get the source Signal filtered for a specifig wavelangth, would make most sense.
I will have a closer look on the optical path when I have some more space on the table to unwind all the fibers.
One of the fibers is guided to the first digital PCB below the optical PCB. I would bet on the PIN diode being in place there together with its friends the transimpedance amplifier, maybe filter and ADC.
