• Typically each substation house will have a patch

panel that will connect the outside fiber to the

insider fiber.

• The patch panel will provide a place to loop

inside fiber for loop testing of relay

• This form can be determined by the type of fiber

and the connections. If there is a patch panel

this will be direct fiber.

• Testing of the relay can be done via looping at

any of the TX/RX connections .

security, but if used it will need to be disabled

during loop testing.
