The OA4SMM4 is a dual input high performance broadband 43 Gb/s Electro-Absorption optical modulator driver amplifier with very low jitter, 4.5 V amplitude, with excellent gain and group delay flatness, matched to 45 GHz. It is designed for electro-optical test equipment and SONET OC-768 / STM-256 optical modulator driver applications. It also supports IQ and QAM modulation.
- Dual 4.5V Outputs
- 0.5ps added RMS jitter
- 6ps rise / fall time
- 17dB gain to 45 GHz
- 20dBm saturated output power
- 3.3W power dissipation
- Size: 1.58 x 1.85 x 0.36 inch
The OA4SMM4 is offered in a small modularized package with superb performance, and is intended for lab use or transponder integration. The OA4SMM4 has gain and power levels that are ideally suited for driving either 40G electro-absorption modulators. The dual driver is well matched so it can be used for differential modulators or with other complex modulation schemes. It has low power dissipation, ample drive signal, very low added jitter, fast rise/fall times, and is easy to use with simple bias voltages.
BTW: The driver board for OA4SMM4 is also available upon request.
