The AQ2744 high-power sensor provides optical input power over a range of -50 to +40 dBm (10 W) and accuracy under reference conditions within ±2.5%. It has linearity of ±0.05 dB (-20 to +37 dBm) and a wavelength range of 800 to 1650 nm. The optical port contains a built-in integrating sphere. The sensor is designed for measuring power of light sources such as Raman amplifiers and pump sources, as well as total power for WDM systems.Ando Electric, Kawasaki, Japan

The Series 4000 fast variable optical attenuator is designed for receiver protection or for use as a safety switch during transmitter turn-up. The device blocks the transmission of light when no voltage is applied and reduces attenuation as voltage increases. Other applications include single- and multi-channel power control, equalization, and optical add/drop. It meets Telecordia GR-1209 and GR-1221 requirements.

The 1926 MAM is a dual booster compact optical amplifier designed for optical crossconnects and metropolitan and access links. It contains two single-channel erbium-doped fiber amplifiers in a package measuring 100 × 90 × 12.7 mm. The two EDFAs are independent, each with an internal 980-nm pump module. The device can reach +17 dBm (50 mW) output in the C-band.
