Optical Transmission Network Solution
There are two resons for service provider to deploy DWDM on its network:
- Traffic volume exceeds 10 Gbit/s and purchasing or renting an additional optical fiber is unprofitable;
- Transmission distance exceeds either 100 km or 120 km. This requires usage of EDFA together with DWDM equipment.
Whats the requirement for DWDM system ?
Capacity: from 40 to 80 wavelengths (i.e., colors), 2.5G/10G/40G/100G per wavelength
- Reliabillity (hardware backup or optical fiber backup)
- Manageability (by Network Management System)
As a solution for DWDM Optical Transmission Network we recommend:
