OXC and OADM are significant nodes in all-optical network.
"We are honored to have been selected as the supplier of the APG system and firmly believe that once completed, APG will have a significant impact and NEC's state of the art advanced Digital Coherent 40G SLTE's and OADM Branching Units will contribute to the economies of Asia and its surrounding countries," said Mr.
An optical add/drop MUX (OADM) can be used to add or drop a specific wavelength along the route of the fiber-optic line.
Leveraging its four internal detectors, the MT9820A analyzes up to 100 nm/s on multichannel optical components such as OADM, WSS, multiplexers, and interleavers.
According to the company, Zhone's GigaMux optical transport system supports a variety of simultaneous single-wavelength and WDM architectures, including point-to-point, OADM linear, and OADM ring configurations; supporting access, metro and regional distances.
The components are appropriate for use as Coarse Wave Division Multiplexers (CWDM) and in Passive Optical Networks, including B-PON, E-PON, G-PON and WDM-PON, SAN, OADM; and also in metro and metro edge networks including LX4 applications.
"Cube Optics' expertise in miniaturized packaging and modular integration of passive components, coupled with Mangrove's advanced platform design, has resulted in a unique, pluggable OADM allowing us to offer our customers an inexpensive, CWDM-based access solution for their ring architectures," said Jonathan Reeves, Mangrove's president and CEO.
Carriers have expressed their need for this flexibility, for single-seat operations, and for proven inter-working between SONET-based systems and WDM-based reconfigurable OADM (ROADM) systems.
Each DWDM vendor's equipment has its own loss budget that is dependent on the actual hardware in use as well as other factors, such as the number of OADM nodes.
This year, real solutions were being offered, with a particular focus on optical add/drop multiplexers (OADM) and wavelength switching, as opposed to just cross-connects.
The French group will also supply SONET 1603 SMX multi-service transmission systems to Dominion, as well as Alcatel 1640 OADM optical insertion extraction multiplexers.
For the new system, NEC provided the submarine cables, submersible repeaters and submersible OADM branching units, as well as subsea monitoring equipment and power feeding equipment.
