Notes
:
1. Having ER = 6 dB guarantees that the –6 dBm minimum output power meets IEEE 802.3ae
requirement of OMA=-5.2dBm.
2. Measured with worst ER; BER<10

– 1 PRBS. Complies with –12.6 dBm OMA at ER = 6 dB.
3. Per IEEE 802.3ae. Equivalent to –13.3 dBm average power at Infinite ER, -11.08 dBm at ER = 6 dB.
8.5Gb/s Fibre-Channel Support:
To operate the FTLX1412M3BCL at 8.5Gb/s Fibre-Channel, the transceiver CDRs need
to be placed in “by-pass” mode by changing the register value in EEPROM-Table 0,
Byte 111, Bit 0.
o EEPROM Byte 111, Bit 0 value for CDRs by-passed: Bit 0 = 1
o EEPROM Byte 111, Bit 0 value for CDRs operating: Bit 0 = 0
By default, a power cycling the transceiver will return the CDRs to normal operation
