The GBIC specification calls for a range of 4.75V to 5.25 volts. The 6V maximum voltage is not allowed for continuous operation, however, TX_DISABLE circuitry in Finisar copper GBICs will function at 6V. +5 Volt Electrical Power Interface Parameter Supply Current Maximum Voltage Symbol Is Vmax Surge Current Isurge Input Voltage Vcc Min 80 4.5 Typ 5 Max 140 6 Units mA V +30 mA 5.5 V Notes/Conditions Hot plug, above steady state current.

Low speed signal parameters (preliminary) TX_DISABLE is a TTL signal as described in Tables 3 and 4. RX_LOS is a CMOS open drain output. MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see section VII, “Serial Communication Protocol”). Note that all Finisar copper GBICs are 'module definition 4' since they support the serial identification protocol. MOD_DEF(1), MOD_DEF(2), and RX_LOS must be pulled up to host_Vcc.
