The status LED's power up default state is ON. The status LED is a user defined
board indicator and can be toggled ON or OFF by writing to Bit 31 of the Control
and Status register. The signal detect LED turns ON if the receiver detects light
and can be used as a simple method of checking that the optical network is
properly connected to the receiver. The Own Data LED is turned ON when the
board detects its own data returning over the network. The default setting is OFF.
The RFM‐5565 is available with a multimode or singlemode fiber‐optic interface.
Figure 1‐4 on page 22 is an illustration of the "LC" type multimode or singlemode
fiber‐optic connector.
