อุปกรณ์แปลงสื่อชนิดจัดการเน็ต ( หนา NMC-100M)

(10M, 100M, 1000M, 10/100/1000M auto-negotiable) net managed media converter are designed for the communication broadband IP MAN (Metropolitan Area Network), which support full-duplex or half-duplex working mode and have perfect network management function based on customers' actual demand. They are the ideal equipments for broadband fiber Ethernet and widely used in the communications level of the metro area broadband network IP solutions.

Function Feature
With the function of 10M/100M, half-duplex /full-duplex auto-negotiation.
Support store-and-forward mode and pass-through mode. The store-and-forward mode supports long packets transmission, while the pass-through mode has no limitation on packets length.
Support bandwidth control.
Support LFP (Link Fault Pass-Through) function. Force other port to stop transmitting automatically when any port of the link is detected to be disconnected.
Support remote network management and remote reset. Enable or disable the Ethernet interface through remote network management system.
The Ethernet interface has the function of MDI-II and MDI-X automatic negotiation, automatic detecting and learning, with perfect compatibility.
Have store-and-forward buffer, which can improve equipments transmission efficiency, with the function of flow control, broadcast isolation, error detection.
Being compatible with IEEE802.1q network characteristic can guarantee most of the main products' main feature, for example, the function of VLAN and TRUNK crossing the switch.
Support cascade function of the network management cards.
Trouble-free working hours are more than 50, 000 hours, in line with telecommunication- grade operating standards.
