Fiber-optic cable connections CH1 to CH4

NOTE

02.2001
The fiber-optic cables are connected via plug-and-socket connectors.
The sockets are located on the front and bottom of the housing. Each
connection (channel) consists of a transmitter and a receiver socket.
The output power of the fiber-optic transmitter is not variable, but
permanently set to the maximum transmitter power defined for
SIMOLINK.
SIMOLINK is a clocked, ring-shaped
fiber-optic bus system. To allow the
flow of signal traffic, the transmit
socket of the first node must be
connected to the receive socket of
the next node and so on, until the
transmit socket of the last node is
connected to the receive socket of
the first node.
The receive socket is dark grey and
labeled RX. The transmit socket is
light grey and labeled TX.
The following Hewlett Packard fiber-
optic modules are installed in the
SIMOLINK Switch:
♦ Transmitter: HFBR 1528
♦ Receiver:
HFBR 2528
Plastic or glass fiber-optic cables can be used. Depending on the type
of cable selected, the inter-node distances are as follows:
♦ Max. 40 m between each node in the case of plastic cables or
♦ Max. 300 m between each node in the case of glass cables.
The maximum permissible ring bus length is 1000 m.
A components package for assembling plastic fiber-optic cable
connections can be ordered under number 6SX7010-0FJ50. This
contains: 100 m plastic fiber-optic cable, 40 fiber-optic connectors, 20
connectors for terminal strip X470 SLB.
If glass fiber optics are the selected medium, the connectors attached
to the fiber-optic cable must be suitable, i.e. they must fit into the
transmit and receive sockets on the SIMOLINK Switch.
