1550nm Single Mode Bandpass Filter

1550nm Single Mode Bandpass Filter

The 1550nm Single Mode Bandpass Filter is a fiber optic filter designed to transmit a selected wavelength band around 1550 nm while suppressing unwanted optical noise and out-of-band signals. Based on high-performance thin-film filter technology, it provides low insertion loss of ≤0.8 dB, high return loss of ≥50 dB, low polarization dependent loss of ≤0.1 dB, and stable optical performance for demanding applications. Standard 1550 nm pass bandwidth options include 2 nm, 5 nm, 10 nm, and 15 nm, with optical power ratings available up to 10 W. It is well suited for fiber lasers, EDFAs and other fiber amplifiers, fiber optic sensing, optical communications, and scientific research. Custom center wavelengths, bandwidths, power ratings, and fiber configurations are also available to meet specific system requirements.
