Hifiber Asf13-24-20-d 1.25gb S Sfp Transceiver With Ddmi 20km Reach Instruction Manual (+ PDF)

Ensure that the power to the host device is turned off.
Locate the SFP transceiver slot on the host device.
Gently insert the SFP transceiver into the slot, ensuring that
the duplex LC connector is properly aligned with the slot.
Apply gentle pressure to firmly secure the SFP transceiver in
place.
Turn on the power to the host device.

2. Connection

Connect the SFP transceiver to the appropriate optical port
using a single mode fiber optic cable with LC connectors. Ensure
that the connections are securely made.

3. Power Supply

The SFP transceiver requires a single +3.3V power supply. Ensure
that the power supply meets the specified voltage requirements.

4. Operation

Once the SFP transceiver is installed and connected, it will
start operating automatically. No further configuration is
required.

5. Troubleshooting

If you encounter any issues with the SFP transceiver, refer to
the troubleshooting section of the user manual or contact customer
support for assistance.

Notes:

1. Circuit ground is internally isolated from chassis ground.

2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

3. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V.

MOD_DEF(0) pulls line low to indicate module is plugged in.

4. LOS is open collector output. Should be pulled up with 4.7k 10kohms on host board to a voltage

between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
