Main Parameters:

Notes:

[1] Excluding connectors, measured at 1550 nm

[2] Tested with SM and PM fiber versions only. For MM version, IL is highly dependent on the CPR source of the light and delay range, Min. RL 35dB.

[3] Variable speed with GUI settings

[4] For core sizes >9 µm. For core sizes <9 µm, power handling capability is reduced. High power versions available on request.

Equation to convert delay time to available space length:

T = L/C = L (m)/(2.9996x108m/s)

Power drive requirements

USB and RS232 interfaces and WindowsM GUI software.

Mechanical dimensions (in mm) (1200ps version)

L=120mm 100ps L=150mm 330ps L=195mm 600ps L=250mm 1200ps L=450mm 2200ps

Order Info:

 By default, there are two connectors on the box. Fiber optic cables are in pairs, each 1m long, with the same connector type at both ends For special needs make "0" and describe all details clearly in the purchase order.

Delay line control (via Windows GUI)

Control via Windows GUI:

1. Set Target Position (mm/pSec)

Simply enter the exact position number (mm) or delay time (pSec) in the text box or drag the slider. Then, click the "Move" button to move the device to the target position.

2. Device Home

If the number is incorrect, the device needs to be calibrated for home. Just click the "Home" button.

3. Scan Function

Drag the slider to the target position/delay time and click "Set Ref x" (x = 1,2). The reference x (x = 1,2) will be set.

The "Go to Ref x" button will allow you to move the device to the reference x.

You can decide the step size of this scan and the delay time for each step. The number of repetitions can also be set. Clicking "Start Scan" will start the current scan process. "Pause Scan" will pause the current scan and you can resume the scan after pausing.

Delay Line Control (via UART Commands (Hex))

Control via UART commands (hex):

T Baud rate is set to 9600-N-8-1.

1. Set motor stage target position

CMD: 0x01 0x14 RTN: 0x01 0x14 E Example: 0x01 0x14 0x00 0x01 0x38 0x80 -> Set device to 80000 position

For 330 ps devices, the position range is 0-80000. 0 means relative to 0 picoseconds. 80000 means relative to 333 picoseconds.

For 660 ps devices, the position range is 0-160000. 0 means relative 0 picoseconds, and 160000 means relative 666 picoseconds.

For 1200 ps devices, the position range is 0-288000. 0 means relative to 0 ps, and 288000 means relative to 1200 ps.

2. Read the motor platform target position

Command: 0x01 0x15 0x00 0x00 0x00 0x00

RTN: 0x01 0x15

3. C Check the current position of the motor stage

Command: 0x01 0x16 0x00 0x00 0x00 0x00

RTN: 0x01 0x16

4. H Home calibration

Command: 0x01 0x20 0x00 0x00 0x00 0x00

RTN: 0x01 0x20 0x00 0x00 0x00 0x00

5. C Check homing status

Command: 0x01 0x21 0x00 0x00 0x00 0x00

RTN: 0x01 0x21 0x00 0x00 0x00

: 0 – homing completed, 1 – homing not completed
