Electrical Power Interface
The GBIC specification calls for a range of 4.75V to 5.25 volts as described in Table 2.
The maximum voltage of 6V is not to be applied continuously.

Notes/Conditions
Table 2. Electrical power interface
Note 1:
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to
specified value applied through the recommended power supply filtering network.
III. Low Speed Signals
RX_LOS, TX_DISABLE, and TX_FAULT are TTL signals as described in Table 3.
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see
section VIII, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)
must be pulled up to host Vcc. For more detailed information, see sections 5.3.1 – 5.3.8 in
the GBIC Specification Revision 5.5
