Availability: In stock


AST-10/100M Fiber Optical Media Converter Series
Dual Fiber Series (Dual Fiber- SMF & Dual Fiber- MMF)

ASTEL series Ethernet media converter can
interconvert electrical signals of 10Base-T and 100Base–TX
twisted pairs with optical signals of 100Base-FX. It extends
the network transmission distance from 100m via copper cables to 20km via fiber optical cable and additional models to extend uptp 120 km are available. It enables the data to transmit in two different mediums of electrical and optical networks either by the technology of data link L2 store-and-forward, or by the one of PHY L1 cut-through.
It supports transmission in multi-mode dual fiber, single-mode dual fiber, single-mode single fiber.

10/100Mbps auto-sensed, facilitating network upgrade
Built-in efficient switching core to implement flow control and reduce broadcast packets
full-duplex and half-duplex auto-sensed
Supporting automatic cross connection of twisted pair interfaces, facilitating system commissioning and installation
Supporting Link Failure Alert (LFA) with optional dip-switch(unique)
Supporting 10/100Mbps store-and-forward and 100Mbps cut-through transmission with optional dip-switch(unique)
Supporting the transmission of extra-long packets up to1600 bytes
Supporting the transmission of extra-long VLAN packets
Supporting Quality of Service (QoS) , ensuring the transmission of VoIP packets
Supporting STP to form a redundant network
Extremely low power consumption, low heat, stable performance and long lifetime
