- Page 5 Never look directly into an optical fiber. Non-reversible damage to the eye can occur in a matter of milliseconds. Do not hook up the 7707DT DWDM cards directly with a short fiber optic cable. The 7707DT DWDM cards produce +7dBm of power, which will damage the receiver if connected directly.

Page 30: Appendix - Mpk Router Control Interface To 7707Dt
The MPK control interface uses a proprietary method of signaling, for which special considerations are required when connecting to other interface types. This application note describes methods for using the 7707DT Fiber Data Transceiver to transport MPK control signals. The 7707DT series Fiber Data Transceivers communicate bi-directional RS-422 and RS-485 data signals over a single fiber optic link. -

Page 32: Interface Methods
From the above overview, it is apparent that special considerations are required when connecting MPK interface signals to the RS-422 or RS-485 interface of the 7707DT. The issue at hand is the high- impedance state that each Control Panel assumes between data transmissions. If several control panel outputs are to be connected together, then this high-impedance state is required to avoid contention of the shared output connection. -
