Ethernet Over STM-1 Converter takes SDH technology as its core to
provide access, convergence, transmission and management functions
of TDM services and broadband IP services, and is a device for
comprehensive access conversion in the applications of conventional
telecommunicating services and broadband data services. The Ethernet Over STM-1 converter is an interface conversion equipment supplied with one STM-1 optical interface and one optical Ethernet interface. All daughter boards of the interfaces support online hot swap.
The design of the SDH converter complies with ITU-T and the
relevant SDH specifications issued by Ministry of Information
Industry, China. Features:
Providing standard STM-1 optical interface ;
Providing an Ethernet optical interface and the maximum of package
length is 2000 byte.
Of excellent synchronous characteristics;
With DC-48V/AC220V/DC-48V+AC220V optical for power supply.
Supports SNMP network management function.
Supports loop-back maintenance functions.
