Notes:
1. Measured by reference TX with 4.75dB extinction ratio at 10
2. When LOS asserted, the data output is Low-Level (fixed)
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 840nm to 860nm transmitted to terminal.
4. Distance, shown in the “Link Length” table, are calculated for worst case fiber and transceiver
characteristics based on the optical and electrical specifications shown in this document using
techniques utilized in IEEE 802.3. In the nominal case, longer distance are achievable.
