FCM -8519-1-T4/FCM-8519-2-T4 Product Specification
II.
Finisar GBICs have an extended power supply voltage range of 4.5V to 5.5V as
described in Table 2. 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.
