They are compatible with Gigabit Ethernet as specified in IEEE 802.32*, single and double rate Fibre Channel FC-PH, PH2, PH33* and SONET specifications for OC-12/OC-48 4**. Along with an extraordinary operation range of –40oC to 85oC, the fiber link budget has been enhanced with an Avalanche Photo Diode (APD) receiver. Additional real time diagnostic functions are available via the 2-wire serial bus specified for Module Definition “4” GBICs. For details, see Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical Transceivers”5. Even with all of these innovative features, the transceiver is still compliant with the mechanical and electrical interfaces defined in the GBIC interoperability standard. © Finisar Corporation December 2004 Rev E Page 1 FTR-1621T-XX WDM GBIC Product Specification – December 2004 Finisar PRODUCT SELECTION FTR-1621T-XX Wavelength 1470 nm 1490 nm 1510 nm 1530 nm I.

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 VIII, “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. 5.51.

Serial Communication Protocol All Finisar optical GBICs are ‘Module Definition “4”’ and support the 2 wire serial communication protocol outlined in the GBIC Specification 1. These GBICs use an Atmel AT24C01A 128 byte E2PROM (with an address of 1010000X). For details on interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2Wire Serial CMOS E2PROM.”6 All Finisar optical GBICs also incorporate a controller IC that monitors system parameters such as laser current, laser temperature, and, in the case of 13xx/14xx/15xx/16xx nm parts, transmitted power. For a complete description of how to use Finisar’s extended features, see Finisar’s Application Note AN-20305.
