The AMP-FL5711-I4S & AMP-FL5711-I4L are specially designed inline amplifiers to extend a reach of bi-directional CWDM signal transmission systems over a single dark fiber. The AMP-FL5711-B4S amplify transmitting signals of 1471, 1491, 1511 and 1531 nm, and pass through recieving signals of 1551, 1571, 1591 and 1611nm with low insertion loss. The AMP-FL5711-I4S & AMP-FL5711-I4L work at the oppsite site. Combination of these inline amplifiers with any CWDM transmitter surely extends transmission distance regardless of signal format and data rate.
