AN-2030: Digital Diagnostic Monitoring Interface for Optical Transceivers

F i n i s a r

1Options

2The bits in the option field shall specify the options implemented in the transceiver as

3described in table 3.6. StandardFinisar SFP transceivers do not implement TX_FAULT

4or RATE_SELECT, so byte 65 set to 00010010b.

6			Table 3.6: Option values
	Data	Bit	Description of option
	Address

	64	7-0	Reserved
	65	7-6	Reserved
	65	5	Indicates if RATE_SELECT is implemented. Finisar does not
			implement this feature.
			NOTE: Lack of implemention does not indicate lack of
			simultaneous compliance with multiple standard rates.
			Compliance with particular standards should be determined
			from Transceiver Code Section (Table 3.4)
	65	4	TX_DISABLE is implemented and disables the serial output.
	65	3	TX_FAULT signal implemented.
	65	2	Loss of Signal implemented, signal inverted from definition in
			Table 1 of the SFP MSA.
			NOTE: This is not standard SFP/GBIC behavior and should
			be avoided, since non-interoperable behavior results.
	65	1	Loss of Signal implemented, signal as defined in Table 1 of
			the SFP MSA.
	65	0	Reserved
7

8BR, max

9The upper bit rate limit at which the transceiver will still meet its specifications (BR, max)

10is specified in units of 1% above the nominal bit rate. A value of zero indicates that this

11field is not specified.

12

13BR, min

14The lower bit rate limit at which the transceiver will still meet its specifications (BR, min)

15is specified in units of 1% below the nominal bit rate. A value of zero indicates that this

16field is not specified.

17

18Vendor SN

19The vendor serial number (vendor SN) is a 16 character field that contains ASCII

20characters, left-aligned and padded on the right with ASCII spaces (20h), defining the

21vendor’s serial number for the transceiver. A value of all zero in the 16-byte field

22indicates that the vendor PN is unspecified.
