1550 nm narrow linewidth laser device has excellent optical performance in terms of high output power stability, high side mode suppression ratio(SMSR), ultra-narrow laser linewidth, low relative intensity noise(RIN), and high stable wavelength. The SM fibers and PM fibers are optional.

Single longitudinal mode Low phase noise Very narrow linewidth, long coherencelength Excellent SMSR
