Product Specification FCM-8519-1-T4 / FCM-8519-2-T4 Copper GBIC Transceiver
Finisar's FCM-8519-1-T4/FCM-8519-2-T4 copper GBIC transceivers comply with GBIC Specification Revision 5.41 . They are compatible with the Gigabit Ethernet 1000BASE-CX standard as specified in IEEE Draft P802.3z/D5.02 and with Fibre Channel FC-PH3 3 . The modules are available with both DB9 (FCM-8519-1-T4) and HSSDC (FCM-8519-2-T4) connectors.

+5 Volt Electrical Power Interface
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. +5 Volt Electrical Power Interface

Table 5. 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. For more detailed information, see sections 5.3.1 - 5.3.8 in the GBIC Specification Rev. 5.41 .
