Your question about Siemens S30807-K5422-X APCF L

Adapter for copper core and optical fiber cables. The maximum range for electrical paths is 240 m, and approximately 6 km for optical paths depending on type of cable. It is used for the connection to a DIUS2 or DIUN2 board from Hicom 300E/300H and Hipath 4000 over a maximum of two S2 stretches for optical connections.

The APCF (Adapter Plug for Copper and Fiber optic), the APCFL (Adapter Plug for Copper and Fiber optic, Long-distance) and the APCFM (Adapter Plug, Copper and Fiber Monomode) are used for linking Hicom systems with S2 (PCM30) paths, by linking either one or two paths (line 1 and line 2) to a common optical fiber point-to-point connection. If only one path is linked to the optical fiber connection, then the second path of the DIUS2 can be additionally used for electrical wave transmission. The system port on the backplane of the DIUS2 module consists of two logical parts:

• Part 1 Interface for transmitting the B-channel signals of the module to the optical fiber connection. The data and clock transmissions are separate for the transmit and receive directions, and a reference clock supply is (implicitly) possible.
• Part 2 Conventional interface for transmitting signals by copper wire.

Interfaces to the system:

• Optical fiber connections (Line 1/Line 2) The adapter plug APCF has an optical output Tx (transmitter) and an optical input Rx (receiver), each consisting of an optical fiber socket for 50 um or 62,5 um graded index fiber with pin plugs. In the outgoing direction, the data of both paths (Line 1 + Line 2) is transmitted in multiplexing mode; in the incoming direction, the optical input may be optionally used by Line 2.
• Electrical connection (Line 2 only). As an alternative to the optical fiber connection, an electrical connection is available for connecting the second S2 path. A 9-pin cannon plug socket enables the connection of copper wire lines with an impedance of 120 ohms (for details of pin assignment see diagram "Adapters APCF, APCFL and APCFM').
