Electrical Power Interface

Finisar FTR-1621-XX WDM GBIC modules have a power supply voltage range of

4.75V to 5.25V as described in Table 2.

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 VI, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)

must be pulled up to host_Vcc. Note – MOD_DEF(0) is grounded inside the GBIC to

indicate the correct mode of operation.

For more detailed information, see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev.
