APPLICATIONS

10GBASE-LR/LW 10G Ethernet

1200-SM-LL-L 10G Fibre Channel

Finisar’s FTLX1475D3BCL 10Gb/s Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-

Gigabit Ethernet links up to 10km over Single Mode fiber. They are compliant with SFF-84311 , SFF-84322 and IEEE

802.3ae 10GBASELR/LW3 , and 10G Fibre Channel 1200-SM-LL-L4 . Digital diagnostics monitoring is available via a 2-

wire serial interface, as specified in SFF-84725 . The FTLX1475D3BCL employs a limiting receiver. The optical transceiver

is compliant per the RoHS Directive 2011/65/EU6 . See Finisar Application Note AN-2038 for more details7 .

Finisar FTLX1475D3BCL SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1

. It is very closely related to the E2 PROM defined in the GBIC standard, with the same electrical specifications. The

standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard

interfaces, manufacturer, and other information. Additionally, Finisar SFP+ transceivers provide a enhanced digital

diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver

temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also

defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters

are outside of a factory set normal range. The SFP MSA defines a 256-byte memory map in E2 PROM that is accessible

over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of

the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is

identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement.

The complete interface is described in Finisar Application Note AN-2030: “Digital Diagnostics Monitoring Interface for SFP

Optical Transceivers”.
