1548.51nm DWDM 14-pin DFB laser module, Pop=10mW. JDS model: CQF935/202-19360. New in original pack with test sheet.With PM fiber (for all CQF935 series products). Terminated with 2.5mm ferrule, there is 400um-coating fiber near the ferrule. The test sheet shows operating power is 10mW, and also shows PM fibre pigtail. Warning: Unlike other CQF series laser, pin-leads of these CQF935/202 lasers are bent (make easier to mount and solder on PCB), see photo as reference. It could be made straight by hand-tool if need. Leads are shorter than regular 14-pin butterfly straight leads, pin length would be about 3mm measured from farthest edge of spare metal body. It is not used laser. It is new laser, customized for some type of PCB.Warning: It does not have pin 10 (WD PD anode). They are all new. So we believe the CQF935/202 is the special version which does not need pin-10 for wavelength lock. This wavelength is around the center of C-band, so it is mostly useful to simulate C-band source.See pdf link for higher-power-version CQF935/708 in the pdf link below.
