III. Low Speed Signals

RX_LOS and TX_DISABLE are TTL signals as described in Table 3. MOD_DEF(1)

(SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals (see section VIII, “Serial

Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to

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

Specification Rev. 5.51.

VIII. Serial Communication Protocol

All Finisar optical GBICs implement serial identification features described for ‘Module

Definition “4”’ as outlined in Annex D of the GBIC Specification1. These GBICs use an

Atmel AT24C01A 128 byte E2PROM at address A0H. For details on interfacing with the

E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS

E2PROM.”6

The FTR-1319-3D-2.5 also supports extended diagnostic features as described in Finisar

Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical

Transceivers”8, and additional information is available in SFF standard titled: “Digital

Diagnostic Monitoring Interface for Optical Transceivers”7 (SFF-8472 rev9.3). A

controller IC that monitors system parameters such as laser current, module temperature,

transmitter po wer, and received power is accessible at address A2H.

I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in

the table below. Values in the table represent the worst-case values over temperature,

voltage, and life.
