CA1782-XXX-XX-EM DWDM High Power CW Buttterfly Laser V1.01

CA1782-XXX-XX-EM DWDM High Power CW Buttterfly Laser

Overview

The CA1782-XXX-XX-EM DWDM High Power CW
Buttterfly Laser component is characterized for use as a CW
optical source in CATV and DWDM networks. The
CA1782-XXX-XX-EM 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 theoptical isolator mounted on the TEC. The
CA1782-XXX-XX-EM incorporates a high efficiency
coupling scheme to deliver 40 mW, 50 mW, 63 mW and 100
mW of CW optical power.

Spectral Linewidth(1)See Page 4nm1. Linewidth (∆ν) is calculated using this formula: ∆ν = ∆RIN(f){16π(Dλ2L/c)2f2}-1
Where: D = fiber dispersion; L = fiber length (65km); C = velocity of light in free space (3.00E+8); λ = opt center wavelength∆RIN(f) = RIN through fiber (RIN65km – RIN0km); f = the measurement frequency (860MHz)
