4E1s+Eth+30VO is an optical transmission equipment realizing long-haul voice transmission through fiber. Interfaces are 30 FXS/FXO, 4 E1 75 Ohm and 10/100BaseTx Fast Ethernet (100 Mbps on the fiber).
This equipment uses design of ultra large scale integration circuits. The merits include easy installation, fast configuration-operation and no maintenance. Fiber optic module can operate in double fiber or single fiber configuration; FXO/FXS ports must be customized in factory and they depend on application and site placed. This equipment helps to bring all kind communication from customer premises to operator central office. Application bring for this optical equipment are:
analog voice (FXO/FXS ports), data (E1 ports), IP Video (10/100BaseTx port) and others.



• Low cost solution for analog voice and data over fiber.
• Up to 30 FXO ports for connection to PABX or PSTN.
• Up to 30 FXS ports for connection of phones (internet dial-up) or faxes.
• Ethernet port for LAN interconnection.
• Up to 4E1 ports as an option for PABX interconnection or any other E1 leased line services application.
• Single or dual optical configurations available.
