Iolon model: LL2040-50-001.01-3.00 . For L-band(since the original buyer only bought them to make L-band DWDM systems). With FC/APC PMF connector. The Iolon Apollo laser is a high performance continuous wave laser for advanced optical networking systems. Capable of providing 10 mW and 20 mW output power.16-pin electrical interface(not like 40-pin interface in the 1st pdf link below). We do not have exact pin-out info for this 16-pin laser module. You may research on the 2nd pdf link below and figure out the pin-out info for 16-pin laser by yourself. One of our customer purchased it before only because he knows how to use internal laser device rather than whole module. You can try it and return it, but you have to take care of two-way shipping cost.
