express OADM

More Flexibility over Fiber Optics

express OADM The flexible express CWDM/OADM concept provides the ideal solution for the increasing bandwidth demand on enterprise and metro access networks.
Also, SANs can benefit from the additional throughput.

Our CWDM/OADM solution is very cost-effective, fully transparent to services and applications and widely scalable.
With our OADM products, we support up to 16 connections of different standards, data rates or protocols transmitted over one single CWDM fiber optic line. ESCON, ATM, Fiber Channel, Gigabit-Ethernet are supported simultaneously, without disturbing each other.

Each OADM device can drop/pass or drop and re-insert one single wavelength.
This allows very flexible designing of point-to-point, ring, or bus configurations.

Due to its purely passive technology, the express OADM series is well-prepared for building a fail-safe and maintenance-free backbone architecture.

See also:
- The express OADM device family can be optimally combined with our express CWDM multiplexer series to meet your specific networking requirements.
- The modular CONV fiber converter and the switch GIGA as a media converter are capable of actively generating OADM/CWDM channel wavelengths.
- Accessories: An assortment of fiber optic patch cables.
