Product description

Our flagship Flexgrid, Colorless, Directionless ROADM solution. Contentionless feature available via redundant Add/Drop modules.
Build up to eight-degree ROADM from Line Degree modules (one per each long-haul connection). Several options are available for local termination of signals via different Add/Drop modules.
Built-in Optical Supervisory Channel at standard 1511 nm eliminates the need to provision an out-of-band management network. No additional amplification for links of up to 25 dB.
The device supports SDN control via RESTCONF, NETCONF and YANG, as well as a local CLI. As a fully integrated CzechLight product, all metrics are available live over model-driven telemetry feed. It has the standard 1U form factor, with redundant fan tray and hot-swap power supplies with AC/DC input options.

Areas of Use

Product Type Use
Line Degree ROADM Module Each ROADM site requires one Line Degree per each connection to nearest ROADM node in other city ("degree"). Up to eight-degree ROADMs can be built.
Add/Drop ROADM Modules Terminate connections locally. The Add/Drop box connects to each Line Degree module by an "express" patch cord.
In-line amplifier Extends reach of Line Degree ROADM modules

Products

Mark Use
CL-R-LINE For connections towards other PoPs.
CL-R-AD-FLEX Adding and terminating up to twenty channels locally. This model provides full control over spectrum, and is therefore suitable for most demanding scenarios with Alien Wavelenghts (AW).
CL-R-AD-COHERENT Local add/drop optimized for coherent channels. Eight channels per one chassis.
CL-R-AD-PASSIVE Adding and terminating channels locally. Optimized fully passive solution for up to eight connections on two-degree nodes.
CL-INLINE C-band amplification. Suitable for in-line installation in scenarios where ROADM nodes are more than 25 dB apart.
