CIP Technologies has introduced a monolithically integrated reflective amplifier-modulator for wavelength division multiplexing (WDM) and dense wavelength division multiplexing (DWDM) networking applications.

Dubbed the R-SOA-EAM-1550, the device monolithically integrates a semiconductor optical amplifier with a reflective electro-absorption modulator to combine high optical gain with high-speed modulation capability.

It is said to offer high output power, low power consumption, and low sensitivity to input polarization, making it suitable for DWDM transmission at speeds of 10Gbit/s over fiber optic links of up to 80km.

The amplifier-modulator is 'colorless' and a single device may be used across the entire C-band.

"Using colorless modulators with remote DWDM light sources is becoming a viable alternative to expensive tunable lasers in WDM-PON and metro applications," commented David Smith, chief technology officer of CIP Technologies.

"This level of device performance represents a breakthrough that will simplify and cost-reduce future deployments," Smith added.

The part incorporates standardized design features to make it compatible with CIP's HyBoard photonic integration platform.
