Product Description
Multimode Converter
The following fiber optic converters have been designed for the distribution of electrical signals over distances of up to 2,000 mtrs. The optical ST connectors are linked via an optical GI50/125 µm or GI62.5/125 µm multimode fiber (wave lenght: 850 nm). The launchable optical output power is typ. 20 µW per output, the minimum optical input level is 3 µW. The elecrical inputs and outputs are provided via female BNC connectors or 9pin SubD connectors. If necessary, the output signals of the digital modules can be inverted against the respective input signal by a jumper inside the aluminium profile housing (71 mm x 84 mm x 24 mm / width x depth x height).
The voltage supply (20 - 60 V DC) is provided by a plug-in power supply unit (100 - 240 V ACIN; 24 V DCOUT) included in the scope of delivery. All converter variants are equipped with a fixing clamp for 35 mm DIN mounting rails.
CON/TTL/FO
The fiber optic module CON/TTL/FO converts an TTL input signal into one or more FO (fiber optical) output signals.
Standard variants (PPS, PPM, 10 MHz, IRIG-B DCLS, TxD):
CON/TTL/FO: TTL In (BNC) to 1 x FO Out
Option: up to 4 x FO Out CON/.../FO-x /Output
CON/FO/TTL
The fiber optic module CON/FO/TTL converts a FO (fiber optical) input signal into one or more
electrical output signals (TTL or RS-422).
Standard variants (PPS, PPM, IRIG-B DCLS, TxD):
CON/FO/TTL: FO In to 2 x TTL Out (BNC)
CON/FO/422: FO In to 1 x RS-422 Out (DB9 female)
CON/FO/TTL/422: FO In to 1 x RS-422 and 1 x TTL Out
CON/FO/FO
The fiber optic converter CON/FO/FO distributes a single optical input signal to multiple optical outputs.
Variants up to 10 MHz:
CON/FO/FO/10M: single ST input via FO receiver (e.g. IRIG-B DCLS / 10 MHz)
Option:
CON/FO/FO-x/10M: FO In into 4 x FO Out
up to 4 x 850 nm Multimode FO outputs via ST connectors.
CON/232/FO
The fiber optic module CON/232/FO converts a RS-232 signal (TxD and RxD) into optical signals.
Standard variants (for RxD and TxD):
CON/232/FO: RS-232 (DB9 male connector) to 1 x FO In and 1 x FO Out
Optional up to 4 x FO Out: CON/.../FO-x /Output
CON/422/FO
This Fiber Optic device converts an RS-422 signal into an optical signal.
Standard Variant:
CON/422/FO: RS-422 (DB9 male connector) to 1 x FO Out
Option: Up to 4 X FO outputs
CON/TCM/FO and CON/FO/TCM
These fiber optic modules carry an amplitude modulated Time Code AM signal over an optical fiber.
Signal delay: 60 µs
Variant to convert a Time Code AM signal to FO:
CON/TCM/FO: Time Code In (BNC) to 2 x FO Out
Variant to back-convert the FO signal to Time Code AM:
CON/FO/TCM: FO In to 2 x Time Code Out (BNC)
Singlemode Converter
Multimode converters are unsuitable to bridge distances over 2,000 m. The following singlemode converters were developed to distribute electrical signals over distances of up to 10 kilometers. The optical ST plug connectors are wired via an E9/125 µm mono-mode fiber (wave-length: 1310 nm). The optical output power is typ. 15 µW (-18 bBm) per output and the optical input has a susceptibility of -30 dBm. The electrical in- and outputs are led out via a BNC socket or a D-Sub9 connector.Even with these modules, the output signal can be inverted against the input signal, if necessary.
CON/TTL/FOS
The fiber optic converter module CON/TTL/FOS for singlemode fibers converts an input signal
(TTL, RS-422 or FO) into one or more fiber optical output signals.
The following options are possible:
CON/TTL/FOS-x:
TTL input (BNC) to one or -x (2 - 4) FOS outputs
CON/422/FOS-x:
RS-422 input (DSub9) to one or -x (2 - 4) FOS outputs
CON/FOS/FOS-x:
FOS input (ST) to one or -x (2 - 4) FOS outputs
CON/FO/FOS-x:
FO (multimode) input (ST) to one or -x (2 - 4) FOS outputs
CON/FOS/TTL
The fiber optic converter module CON/FOS/TTL for singlemode fibers converts an optical input
signal into one or more electrical output signals (TTL or RS-422).
The following options are possible:
CON/FOS/TTL: two TTL outputs via BNC female connectors
CON/FOS/422: one RS-422 output via D-Sub9 female connector
