摘 要: | A chirped fibre Bragg grating according to ITU-T suggested L-band
(2nd channel $\lambda _{1}=1570.83$~nm; 80th channel $\lambda
_{2}=1603.57$ nm) with more than 1800 ps/nm single channel dispersion
compensation is presented in this paper, of which the cladding mode
loss, the delay curve ripple and the power fluctuation of the
reflected spectrum are less than 0.5 dB, 50 ps and 0.25 dB,
respectively. With this new FBG as dispersion compensation device, a
$2\times 10$ Gb/s wavelength division multiplexing (WDM) L-band
transmission of 600 km based on conventional single mode fibre (G.652
fibre) is performed without forward error correction. The bit error
rate (BER) is less than 10$^{ - 12}$ and the power penalties of the
2{nd} and 80{th} channel of L-band are 1.8~dB and 2.0~dB,
respectively.
