Reconfigurable Optical Add/DropMultiplexer
Optoplex’s Reconfigurable Optical Add/Drop Multiplexer (ROADM) module, also known as
Tunable Optical Add/Drop Multiplexer (TOADM), is based on a proprietary micro-optics and microactuator design, athermal packaging technology, and state-of-the-art thin-film coating. When receiving astream of optical signals of a plurality of wavelengths from the Input-Port (IN), this 3-port ROADM
device directs a selected channel to the Drop-Port (ADD/DROP) and the remaining channels to theExpress-Port (EXP), as depicted in the figure below. This tunable feature can also be used for adding achannel, when the device is used in reverse. Cascading two ROADM modules, simultaneous add anddrop functions can be achieved. Each single ROADM device is optimized to cover either C- or L-band
wavelengths. The standard 100- or 200-GHz channel spacing ROADM products allow for single-channel
drop. Customized banded-channel drop ROADMs are available upon request.
