Notes:
1. Max output optical power is lesser than Class 1 safety limits (CDRH and EN 60825)
-12
2. Measured by reference TX with 4.75dB extinction ratio at 10 BER
3. When LOS asserted, the data output is Low-Level (fixed)
4. 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.
5. 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.

Note:
1. The module signal ground pins, VeeR and VeeT, shall be isolated from the module case.
2. This pin is an open collector/drain output pin and shall be pulled up with 4.7k-10k ohms to Host_Vcc
on the host board. Pull ups can be connected to multiple power supplies, however the host board
design shall ensure that no module pin has voltage exceeding module VccT/R + 0.5V.
3. This pin is an open collector/drain input pin and shall be pulled up with 4.7k-10k ohms to VccT in the
Module.
4. This pin shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board.
