The 1782 laser component is characterized for use as a CW optical source in
CATV and DWDM networks. The 1782 is dc-coupled with a built-in TEC,
thermistor, and monitor photodiode. The device is mounted in a 14-pin, OC-48
pinout compatible butterfly package with the optical isolator mounted on the TEC.
The 1782 incorporates a high efficiency coupling scheme to deliver 40 mW, 50
mW, 63 mW and 100 mW of CW optical power.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the
operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect
device reliability.

1. Linewidth () is calculated using this formula:
=
RIN(f){16(D2L/c)2f2}-1
Where: D = fiber dispersion; L = fiber length (65km); C = velocity of light in free space (3.00E+8);
= opt center wavelength
RIN(f)
= RIN
through fiber (RIN
65km
– RIN
0km
); f = the measurement frequency (860MHz)
