Digital Fiber Optic Link AFL-300

AFL-300 DIGITAL FIBER OPTIC LINK

Actual Size: 61 x 61 x 28mm (box only)
Price starting from $794.- per pair (Transmitter and receiver units), basic TTL configuration, Multi-Mode.

When you need:
  To transfer a trigger signal from a noisy environment,
  To isolate the signal from high voltage sources,
   Eliminate ground loops,
   Transfer precise timing signals over a long distance,
   Have excellent system reliability,
The AFL-300 Digital is the answer.

The AFL-300 digital is an excellent solution for transmission of precise timing signal over optical fibers. Those signals can be triggering signals, synchronisation signals, GPS timing signals and any other TTL compatible signals (0 to 5V or 0 to 12V).

The input to the AFL-300 is a logic input, 0 to 5V or 0 to 3.3V (0 to 12V per request).

The signal is transferred over the optical fiber with minimum latency and almost zero jitter.
The signal is reconstructed on the receiver and can be output as a TTL signal (0 to 5V), 0 - 12V signal or open collector (up to 30V external voltage).

The AFL-300 consists of the following components:
  A Digital Fiber Optic Transmitter - AFL-300 DIG/TX,
  A Digital Fiber Optic Receiver - AFL-300 DIG/RX,
  Up to 3 km of of Multi-mode glass fiber or 50 Km of Single-mode fiber (optional).
Optical budget with Single Mode transceivers: 28 dB.

The link is connected between the signal source at the transmitter and the signal output at the receiver.

Features
Transmit precise timing signals over optical fiber.
  Prevents ground loops and computer noise effects .
  Transfers analog signals to distances of up to 3 Km (50Km with Single Mode transceivers)
  Excellent signal isolation.
  Short propagation delay - 200 nSec + 5 uSec/Km.
High Frequency bandwidth: DC to 10 MHz.
  Very small size: only 61 x 61 x 28 mm
  Low cost: $794.- per pair (Rx + Tx).
Can work under Ionizing radiation (Nuclear applications)

Technical Specifications
  Input/output Range: ±5 V standard; input is compatible with 0 to 3V logic as well,
Output can be switched by user between 0-5V to 0-12V to Open collector .

BETTER JITTER SPECS ON REV.#D UNITS:
  Low Jitter - Up to 300pSec. using MM fiber.
Using SM fiber the jitter is less than 100pSec on the Rising edge and in most frequencies or pulse width it is the same on the falling edge. On few particular frequencies the jitter on the rise time only might be up to 45 nSec. This can be adjusted by the factory so it would not interfere with your signals. It may be reversed by the factory to have low jitter on fall time and higher jitter on rise time.
  Frequency Response: DC to 15MHz .
Low output noise
  Supply Voltage: 12 V regulated, floating power supply. 24V Optional.
  Optical Fiber: Glass, 62.5/125 micron dia. Standard (up to 3 Km), ST connector standard,
Single Mode fiber (Optional) - 9/125 micron, ST connector.
  Transmission Range:
- Up to 3 Km standard (MM Fiber), 50Km optional with Single-mode fiber
Optical budget with Single Mode transceivers: 28 dB .
  Voltage Isolation:
- Input to Output - infinite voltage isolation,
- Input/Output to Mains - standard 800V, Optional up to 2500 V,
- Battery operated - infinite voltage isolation.
Can work under Ionizing radiation (Nuclear applications)

Jitter for SM model:
12V Output option

Oscilloscope error is 1/Sampling Rate = 100pSec.

Jitter is lower than 100pSec.

Jitter for MM model:
12V Output option

Oscilloscope error is 1/Sampling Rate = 100pSec.

Jitter is lower than 300pSec.

Sample Application:
Synchronization of GPS receivers to produce precise timing signals:
Master GPS receiver is transmitting precise timing signals in IRIG-B002 DC Level Shift format (DCLS) to other receivers. Receivers are compensated for transmission delays and create precise, synchronised timing signals and timing code.

Ordering Information
  The AFL-300 Digital is available with Single-Mode optics or Multi-Mode optics
  Input range is TTL (0-3V or 0-5V). Output range can be adjusted by user (0 to 5V, 12V or Open Collector). Other input and output ranges available per request (0-12V, 0-24V etc.)
  A stabilized power supply is also required for each side. It can supply power for up to 5 (optionally 10) receivers or transmitters.

EXAMPLE:
TRANSMITTER / RECEIVER PAIR:
AFL-300 DIG- - SM - R- DIN - 24V - 50B
Where:.
SM = Single Mode (MM =Multi-Mode optics is the standard ).
R = Range in meter
DIN = DIN rail holders
24V = 24V power supply inputs (instead of standard 12V power input)
50 = 50 Ohms termination (please specify: 50Ohm @ Input/Output/Both or TTL).
Optical Splitters are available in different splitting ratios. Please consult the factory for your system design.
