Overview
The Allied Telesis MMC Series of mini
media converters leverages its smaller
size to not only help the environment
with a small carbon footprint, but
also to save space in its working
environment. Despite its compact size,
the MMC Series delivers all the power
and functionality of standard size
media converters.
Extend Networks
The MMC Series are available in
100Mbps or 1000Mbps models.
Depending on the model chosen,
the fiber-optic port has options for
fixed SC, ST, LC or SFP connectors
capable of multi-mode or single-mode
fiber connectivity. The twisted-pair
copper port has an RJ-45 connector
supporting either 100Mbps or
1000Mbps, with a maximum operating
distance of 100 meters (328 feet).
VLAN Support
Many new backbone switch products
now support the industry-standard
IEEE 802.1Q specification for Virtual
LANs (VLANs) that send extra-long
data packets on the network. The
MMC Series are fully compatible with
these long packets, enabling them to
be used in modern networks.
Media converters not supporting
this feature discard these extra long
packets, making them unsuitable for
modern networks.
Small and Flexible
The smaller size and external power
supply of the MMC Series allows them
to be used almost anywhere.
Smart MissingLink (SML)
The Smart MissingLink™ (SML) feature
monitors network connections and
provides notification when network
segments fail, allowing network
managers to quickly identify the source
and location of failed segments and
minimize downtime.
Smart Link Restoration
Smart Link restoration allows the
devices, in cases of power failure, link
loss or other interrupted service, to
automatically restore the link without
the need to restart/reset them.
Power Saving
The MMC Series continues the Allied
Telesis commitment to the environment
with over 50% power savings.* With
just 1.7W of power usage, the MMC
Series media converters are some of
the most efficient in the market today.
Link Test
The link test is a fast and easy way for
you to test the connections between
the media converter ports and the
connected end nodes. If a network
problem occurs, you can perform a
link test to determine which port is
experiencing a problem, and focus
your troubleshooting efforts on the
right cable or end node.
New Features
*Over previous models
Mini media converters offer a smaller size and smaller carbon
footprint to help the environment and save space in the office.
