Foreword



The development work on this specification was done by the SFF Committee, an


industry group. The membership of the committee since its formation in August 1990


has included a mix of companies which are leaders across the industry.

< p>


During the development of the form factor definitions, other activities were


suggested because participants in the SFF Committee faced more problems than the


physical form factors of disk drives. In November 1992, the charter was expanded to


address any issues of general interest and concern to the storage industry. The SFF


Committee became a forum for resolving industry issues that are either not addressed


by the standards process or need an immediate solution.

Those companies which have agreed to support a specification are identified in the


first pages of each SFF Specification. Industry consensus is not an essential


requirement to publish an SFF Specification because it is recognized that in an


emerging product area, there is room for more than one approach. By making the


documentation on competing proposals available, an integrator can examine the


alternatives available and select the product that is felt to be most suitable.

that


were not considered in the SFP MSA or GBIC documents.



The


interface


is


an extension of the


two-wire


interface


ID


interface


defined


in the


GBIC specification as well as the SFP MSA. Both specifications define a 256 byte


memory map in EEPROM which 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 two-wire interface ID


memory map remains unchanged. The interface is backward compatible with both


the GBIC specification and the SFP MSA.

概述



The enhanced digital diagnostic interface is a superset of the MOD_DEF interface


defined in the SFP MSA document dated September 14, 2000, later submitted to


the


SFF


Committee


as


INF-8074.


The


2


wire


interface

definitions,


hardware,


and timing are clearly defined there.

document


describes


an


extension


to


the

The

(A2h)


to


provide


diagnostic


information


about


the

conditions.


The


transceiver


generates


this


diagnostic


data


by


digitization of internal analog signals. Calibration and alarm/warning threshold data


is written during device manufacture.



All bits that are unallocated or reserved for SFF-8472 shall be set to zero and/or


ignored


.


Bits labeled as reserved or optional for other usage, such as for SFF-8079, shall b

implemented

协议中,所有的未被分配的或者被保留的数据位应该被设置为

If optional features for SFF-8472 are implemented, they shall be implemented as


defined in SFF-8472. If they are not implemented, then write bits will be ignored,


and state bits shall be set to zero.



Additional A0h and A2h memory allocations were provided in revision 9.5 to


support multi-rate and application selection as defined in SFF-8079 and SFF-8089


documents.



Extensions have been made in revision 10.4 to several tables documenting new


connectors, industry form factors and transceiver codes.



如果

The assumption for this example is the transceiver is



4-2-1



compatible, meaning operational at 4.25 Gb/s,


2.125 Gb/s & 1.0625 Gb/s.


2



To distinguish between 1000BASE-LX and 1000BASE-LX10, A0h Bytes 12 to18 must be used



see Tables 3.1 and


3.1a for more information.


3



See A0h Bytes 60 and 61 for compliance of these media to industry electrical specifications.


4



For Ethernet and Sonet applications, data rate capability of these links will be identified in A0h Byte 12


[nominal bit rate identifier]. This is due to no formal IEEE designation for passive and active cable interconnects,


and lack of corresponding identifiers in Table 3.5.

The encoding value indicates the serial encoding mechanism that is the nominal design target


of


the


particular


transceiver.


For


devices


supporting


multiple


encoding


types,


the


primary


product


application


should


dictate the


value chose


(ie. for 16G/8G/4G


or 10G/1G,


a


value


of


06h


should


be


chosen).


The


value


shall


be


contained


in


the


two-wire

data.


The


defined encoding values are shown in Table 3.6.



编码值表示作为特定收发器的标称设计目标的串行编码机制。



对于支持多种编码类型的设备,



要产 品应用应该指定所选择的值(即,对于


16G / 8G / 4G



10G / 1G


,应选择


06h


值)。



该值应


包含在两线接口数据中。



定义的编码值如表


3.6


所示。

< p>








BR, nominal [Address A0h, Byte 12]



The nominal bit (signaling) rate (BR, nominal) is specified in units of 100 MBd, rounded off


to


the


nearest


100


MBd.


The


bit


rate


includes


those


bits


necessary


to


encode


and


delimit


the


signal as well as those bits carrying data information. A value of 0 indicates that the bit rate is


not specified and must be determined from the transceiver technology. The actual information


transfer rate will depend on the encoding of the data, as defined by the encoding value.



Rate Identifier [Address A0h, Byte 13]



The rate identifier byte refers to several (optional) industry standard definitions of Rate_Select


or


Application_Select


control


behaviors,


intended


to


manage


transceiver


optimization


for


multiple operating rates.
