Connection Technology Systems (CTS) CVT-3112 series are Gigabit Ethernet 10/100/1000Base-T to 1000Base-X media converter which is designed to fulfill the emerging deployment needs of ber Ethernet network for operators and service providers with SNMP managed functionality. When CVT-3112 is deployed at customer premises, the media converter can be fully managed by the network equipment in the Central O ce site by popular SNMP based network management server (NMS). By leveraging the benfits of CTS unique SNMP based power down trap feature, the CVT-3112 is able to send SNMP based trap message to NMS immediately when detects power failure on converter at customer site. It can signi cantly reduce truck rolls and save the operational cost (OPEX) for operators or service providers. The CVT-3112 series media converter allow the user to connect Ethernet twisted-pair network to fibre Ethernet network easily and extend the transmission distance from 10km to 80km maximized. The optical interface of media converter provides a wide range of options to fit the practically need of fibre network deployment for the customer included multi-mode, single-mode and bi-directional transmission over just one single fibre as well as the SFP slot for pluggable fibre transceiver. The CVT-3112 series media converter is fully compliant with IEEE802.3/802.3u/802.3ab & 802.3z standards. The installation and operation procedures for CVT-3112 are quite simple and straight forward. The user can simply configure the built in popular layer 2 and managed features by using commonly Web management UI to monitor the operation status easily in real time.
