Overview
Introduction
To create reliability in your network, the 4 10/100/1000T + 4 SFP
Managed Industrial Switch comes equipped with a proprietary
redundant network protocol—X-Ring provides users with an easy way
to establish a redundant Ethernet network with ultra high-speed
recovery time less than 20ms. Also, the long MTBF (Mean Time
Between Failures) ensures that the industrial switch will continue to
operate until a Gigabit network infrastructure has been established,
without requiring any extra upgrade costs.
Aside from 4 x 10/100/1000Base-T fast Ethernet ports, the 4
10/100/1000T + 4 SFP Managed Industrial Switch comes equipped with
4 SFP (mini-GBIC) ports. Traditional RJ-45 ports can be used for
uplinking wide-band paths in short distance (< 100 m), while the SFP
slots can be used for the application of wideband uploading and long
distance transmissions to fit the field request flexibility. Also, the long
MTBF (Mean Time Between Failures) ensures that the 4 10/100/1000T
+ 4 SFP Managed Industrial Switch will continue to operate until a
Gigabit network infrastructure has been established, without requiring
any extra upgrade costs.
The SFP Advantage
The SFP fiber slots provide a lot of flexibility when planning and
implementing a network. The slot can accept any SFP-type fiber module
and these modules are designed for transmitting over distances of
either 550m (multi-mode), 10km, 30km, 50km, 70km or 110km
(single-mode)—and the slot supports SFP modules for WDM
single-fiber transmissions. This means that you can easily change the
transmission mode and distance of the switch by simply pulling out the
SFP module and plugging in a different module. The SFP modules are
hot-swappable and plug-and-play.
