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.

Etalon-based OEM wavelength-locker modules are designed for integration with telecom laser packages and can be configured for either rear-facet monitoring of a DFB laser or front-facet monitoring of a DBR laser. They allow the frequency of the lasers to be held to within 1.5 GHz and are designed to operate with 2.5-GHz channel spacing. Their temperature sensitivity is <3 pm/°C.

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.
