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.

The problems faced by
integrators, device suppliers, and component
suppliers led to
the formation of the
SFF Committee as an industry ad hoc group to
address the
marketing and engineering
considerations of the emerging new technology.
集成商,设备供应商和组件供应商面临的问题导致成立
SFF
委员会作为行业特设小组来解决新兴技术的营销和工程考
虑。
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.

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.

Diagnostic Monitoring Interface for
Optical Transceivers
Page 6
This
document
defines
an
enhanced
memory
map
with
a
digital
diagnostic
monitoring interface for optical
transceivers that allows pseudo real time access
to
device
operating
parameters.
It
also
adds
new
options
to
the
previously
defined
two-wire
interface
ID memory
map
that
accommodate
new
transceiver types
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.
这个文件定义了一个带有数字诊断接口的增强型的内存表,数
字诊断接口是为收发机服
务的,这可以让虚实时系统能够获得
设备的测量参数。它同样加入了新的选项到先前定义的
两线的存储表中,以便于兼容新的
SFP
MSA
或者
GBIC
文件的收发器类型。
接口是一个在
GBIC
或者
SFP
MSA
说明书中定义的两线的接口
ID
的扩展。两个说明书
定义的
256
字节的存储表可以通过串行的两线接口在
8
位的地址结构
1010000X
p>
(
A0h
)处
得到访问。数字诊断监控接口利用的是
8
位的地址
1010001X
(
A2h
),这样原始定义的两线
的接口
ID
存储表就可以保持不变。这些接口既向后兼容
GBIT
又兼容
SFP
MSA
。

Interface Definition
增强的数字诊断接口定义
Overview
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
pin
definitions,
hardware,
and timing are
clearly defined there.
增强数字诊断接口是一个在
2000
年
9
月
14
日的
SFP
MSA
文件数据定义的
MOD_DEF
接口,之后,遵从了
SFF
委员会后变成了
INF-8074<
/p>
。涉及两线的接口的定义、硬件、和时
序都在这里被清晰的定义了。
This
document
describes
an
extension
to
the
memory
map
defined
in
the
SFP
MSA
(see
Figure
3.1).
The
enhanced
interface
uses
the
two
wire
serial
bus
address
1010001X
(A2h)
to
provide
diagnostic
information
about
the
module?s
present
operating
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
e
implemented per such
other documents, or set to zero and/or ignored if
not
implemented
.
这个文件描述了一个在
SFP
MSA
(见图
3.1
)存储表的扩展。增强的接口用两线串行总
线地址
101001X
(
A2h
)来提供模块的当前的作业环境条件的信息
。收发器通过检测模块内
部的模拟信号来收集这些监测数据、
校准和告警
/
警告。门限在设备制造的时候被写入。
SFF-8472
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
0
,
及
(
p>
或
)
被
忽略。
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

For each of the three bit rates, a

Two

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

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,

该值应
包含在两线接口数据中。
p>
定义的编码值如表
3.6
所示。
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.

包含了一些编码和划定信号界限。如果某一位的值是
0
,那么这就表明这一位没有被指定,
这一位必须要被收发器采用相应的技术来检验。实际的传输速率依赖于编码的方式,实际
