Features
The FL SWITCH SFN… range of Factory Line switches with
standard functions in numerous versions can be used for
quick and cost-effective Ethernet network expansion to the
field level. Due to their narrow housing design, the
components are suitable for universal remote use in control
cabinets and junction boxes. The switches have five or eight
ports, up to two of which are glass fiber ports provided in SC
or ST format. The switches support the auto negotiation
function at the twisted pair ports and offer transmission
speeds of 10/100/1000 Mbps depending on the switch
version. Mixed operation for the connection of segments
with different data transmission speeds is also supported.
The glass fiber ports only support 100 Mbps or 1000 Mbps
(Gigabit version).
The RJ45 ports offer an auto crossing function, which means
it is not necessary to make a distinction between 1:1 and
crossover cables.
The fiber optic ports can be used to extend the segment
length up to 20 km. Unused RJ45 ports can be fitted with
security caps to provide mechanical protection against
unauthorized use.
The FL SWITCH SFN…GT… switches offer additional
gigabit performance, alarm contact and redundant power
input capability.

Increased network performance
– Switched Ethernet reduces traffic and non
predictable timing
– Quality of Service: Pretagged high priority
messages are forwarded before lower priority
messages during periods of high network traffic
loading
– Gigabit options for data intensive applications
– Gigabit switches support jumbo frames up to
9600 bytes per frame
Easy network expansion
– No configuration of the switch
– Auto negotiation and autocross simplify cabling
– Coupling copper network segments with different
bit rates with automatic detection of the data
transmission speed of 10 Mbps, 100 Mbps or
1000 Mbps depending on the switch version
Fiber optic options extend distance and electrical noise
immunity
– 1- or 2-port options
– SC or ST connector options
– Multimode or singlemode option
Low cost, low complexity security (optional)
– Connect Layer 1 security elements at the RJ45 port
to restrict access or tampering
Please note the different connection directions of the transmission media for five-port switches : copper cables
are connected at the front , glass fiber cables at the bottom .
Make sure you always use the latest documentation.
