• Manufacturer Part Number: afbr-820bz
• Description: Twelve-channel Transmitter And Receiver Pluggable, Parallel-fiber-optic Modules
• Manufacturer: Avago Technologies

Transmitter Electrical Characteristics*
The following characteristics are defined over the Recommended Operating Conditions unless otherwise noted. Typical
values are for Tc = 40°C, Vcc33 = 3.3 V and Vcc25 = 2.5 V.
Notes:
*
1. Supply current includes that of all Vcc25 contacts.
2. Supply current includes that of all Vcc33 contacts.
3. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance of 100 :
4. Measured over the range 100 MHz to 3.75 GHz with reference common mode impedance of 25 :
5. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance of 100 :
6. LOS Hysteresis is defined as 20 Log(LOS De-assert Level / LOS Assert Level).
7. Power On Initialization Time is the time from when the supply voltages reach and remain above the minimum Recommended Operating Conditions
