You can select wavelength among 1309nm, 1556nm, and 1631nm at the front panel of the instrument. Laser modules are in 14-pin butterfly with TEC (see 8th photo below). There are one 1x3 optical switch (JDS P/N: SW13-Z321) inside the instrument to select laser source module. The lasers are driven by a regulated linear power supply (GHOF 1-5 Rev.A, output 5V 3.0A).
FC/PC adapter at output port. Internal SM fiber connector looks clean under fiber scope for female connector.
We tested output power after at least 40 minutes warmup (see 3rd photo) and optical spectrum (see last 6 photos). Center wavelength data is from OSA test with RBW=5nm or 10nm, there is no enough warmup for OSA test). Optical output power is quite stable. Tested laser output power and center wavelength (OSA RBW=10nm):
-3.521dBm 1305.94nm at 1309nm port.
-1.123dBm 1553.45nm at 1556nm port.
-6.425dBm 1630.63nm at 1631nm port.
Original tested optical spectrum result by JDS was labeled on 3rd photo below.
AC input: 110V/120V is standard option. Upon your request, we can change to other AC input voltage option by re-wiring inside instrument. A power cord will be attached.
