OEO features:

There are many types of OEO equipment: different types of equipment can be selected according to the specific needs of customers.

OEO flexible and transparent access to multiple rate services: it provides multiple rate service interfaces and supports Ethernet, PDH, SDH, ATM and other services.

OEO relay type: wavelength conversion, mode conversion, optical power shaping and amplification.

The repeatable transmission distance of OEO: 30km, 50km, 80km, 100km, 120km.

OEO supports network management functions: it provides a variety of network management methods, including local management in the terminal console, remote login network management in Telnet, webriver management in web, and intuitive GUI Graphical interface management mode in SNMP

Technical parameters of OEO equipment:

Note: if the distance between the two machine rooms is more than 80km standard optical fiber distance, but there is a relay point in the middle, OEO can extend the transmission distance to 160km standard optical fiber distance with the cooperation of long-distance optical module.

Note: if the equipment is a double fiber optical connector in the two machine rooms, only one core optical fiber can be used for the line. The double fiber optical connector can be converted into single fiber optical joint through OEO, so as to realize the demand of single fiber transmission.

OEO multifunctional power amplifier can amplify the optical power of fixed wavelength system. The optical interface is designed in the form of SFP. The optical module can be replaced at any time. A single set supports the amplification of one optical signal, and supports the mutual conversion of any wavelength, the conversion of single fiber interface to double fiber interface and the conversion of Ge optical interface to ge electrical interface. It can be widely used in communication scenarios of optical signal amplification and optical interface conversion.
