the middle wire is the grounding wire.
Before connecting circuit, please use big spec (#20AWG or bigger) electric
wire to connect the grounding screw on the bottom and the grounding frame.
When use DC input power supply, the equipment chassis must be grounding.

Clean all fiber patch cords before connecting to the transmitter.
Cleaning Guidelines:
Fiber Patch cord connectors
- Remove the fiber connectors dust cap and wipe the fiber connector tip
with a dry lint-free cloth (such as Kimwipes). Inspect for scratches or
debris on connector surface by using a microscopes (ie.100x or 200x).
- If no scratches or debris are found the connector is now clean and ready
for connection. If debris or scratches are found then repeat the fiber
patch cord connector cleaning guidelines.
Fiber Bulkhead connectors
- Compressed air may be used to clean fiber bulkhead connectors. Use
compressed air with at least the following specifications:
- Non-residue, inert gas for precision dust removal
- Ultra-filtered to < 0.2 microns
- Recommended for optical systems
- Using compressed air as listed above, remove the bulkhead dust
cover and hold the can of compressed air about 6 inches from the
connector. After spraying a few short bursts into the bulkhead the
connector is clean and ready for connection.
- If compressed air is not available, the transmitter fiber bulkhead
connector may be cleaned by 2.5 mm cotton swap or connector plate
may be removed to clean the internal fiber patch cords.
- To remove the transmitter optical connector plate, remove the screw on
the far left of the optical plate and remove the screw on the far right of
the optical plate. Do not remove the screws on the optical bulkhead
connector.
- Slowly remove the optical connector plate from the rear panel and
disconnect each fiber connector from the bulkhead mounted on the
plate.
CAUTION
: Be cautions when handling fibers.
Do not exceed fiber manufacturers pulling tension or bend radius specifications
when removing fiber bulkhead connector plate.
