2. Overview
The MCT-2612 series media converter converts traditional
twisted-pair RJ-45 cable into various fiber media including
multi-mode, single-mode, SC connector, bi-directional WDM, or
a SFP slot for pluggable fiber transceiver, extending
transmission distance for the deployment to the household,
apartment or campus.
MCT-2612 series media converter is fully compliant with IEEE
802.3, 802.3u standards.
Besides, it is equipped with some switching features including
store and forward. Operation status can be locally monitored
through a set of Diagnostic LED located in the front panel.
Major Features:
Auto-Negotiation in TP port
MDI/MDIX Auto-Crossover supported
Support Jumbo Frame 9K bytes
Store and Forward Switching Mechanism
Support Auto & Force mode configuration
Attach fiber cable from the MCT-2612 to the fiber network.
The fiber connections must be matched – transmit socket to
receive socket.
Attach a UTP cable from the 10/100BASE-T network to the
RJ-45 port on the MCT-2612.
