OptoSpan OTSS-TMSTFS-X3L (Mfr. Japan) is a Fixed In-line fiber optic 3dB ST attenuator that can be quickly installed in your single-mode (1310/1550nm) optical link to reduce optical power. This Simplex ST/Male to ST/Female premium grade attenuator (Return Loss: UPC ? -50dB, APC ? -60dB) can accommodate up to 200mw high power and offer very low attenuation tolerance of less than 0.5dB (1-10dB: ? .5dB, 11-25dB: 5% x Attenuation). It features polarization-insensitive doped fiber with premium ceramic ferrules to provide precise alignment. OptoSpan Fixed In-line fiber-optic attenuators are generally used to test power levels or calibrate an optical link by adding attenuators to match transmitter and receiver power levels. OptoSpan premium attenuators are rated for temperature range of -40C to +85C and are Bellcore compliant.
