Note (2). When LOS asserted, the data output is Low-level (fixed)
Note (3). When the terminal is viewed from the optical path, the reflection toward the optical path of the

optical signal with a central wavelength of 1480nm to 1580nm transmitted to terminal.

Note (4). These are 20%~80% values

Note (5). X=10 MHz, Rectangular BER =10

Note (4). Internally AC coupled with LVPECL output, but requires a 100Ohm differential termination at or

internal to Serializer/ Deserializer.
