From multi-card designs to chip level

The OADM is the first product in a series of chip-scale OADM Integrated- Circuits.
The OADM integrates the functionality of 30 different optical and electronic discrete components in a single, small-size device. The component provides integrated optical performance monitoring, coupling, attenuation and protection switching, all on the same silicon together with an integrated control.

The OADM enables system designers to:
Eliminate complete optical cards, such as separate switching & monitoring cards, allowing designers to achieve more cost competitive solutions
Reduce more than 50% in footprint and chip count
Eliminate multiple external fiber coupling and splicing, which improves optical boards manufacturability, cost and board space

Highlights:

1. A complete OADM subsystem on a chip
2. Fast protection switching [300us max]
3. Integrated Power Monitors and fast Variable Optical Attenuators (VOA)
4. Automatic equalization of output power level (AGC)
5. Low insertion loss for Through and ADD/Drop channel (only 1.6dB)
6. Digital control by SPI/I2C interface
7. Unprecedented small size for integration into:
   - Transceivers
   - Optical function cards on existing SONET/SDH muxes, switches, IP routers, etc...
8. Excellent price/performance
