Operation principle:
1, the detection of SD signal, the SD signal of some light unit is Transistor-Transistor Logic level high level, and some is LVPECL level, for
Can detect SD signal more accurately, SD signal received the ADC pin of single-chip microcomputer by us, by the electricity of ADC detection SD signal
Press, be high when the value of ADC reading is more than 2V, SD, be then low when the value of ADC reading is less than 2V.
2, single-chip microcomputer powers on and first detects the level of SD signal, if having light unit also above high level explanation transceiver
And led to light, and afterwards by metal-oxide-semiconductor by light unit power-off, it is 1000M by light cell location, powers on to light unit, then single
Sheet machine reads the light mouth status register of exchange chip by SMI interface, on detection light mouth whether Link, if light mouth LINK
UP then illustrates that light mouth is gigabit, and otherwise explanation light mouth is 100,000,000, and Jiang Guangkou is configured to 100,000,000.Then be further continued for detection until
SD signal is low level.Enter detection configuration next time.
3, single-chip microcomputer powers on and first detects the level of SD signal, if not having light unit above low level explanation transceiver
Or light unit does not lead to light, then detection SD signal level, until SD signal is high level, specification module has been led to,
Being 1000M by light cell location afterwards, power on to light unit, then single-chip microcomputer reads the light mouth of exchange chip by SMI interface
Status register, on detection light mouth whether Link, if light mouth LINK UP, illustrates that light mouth is gigabit, otherwise explanation light mouth
Being 100,000,000, Jiang Guangkou is configured to 100,000,000.Then the detection level until SD signal it is further continued for.Enter detection next time to join
Put.
1,1*9 light unit is that can not directly to read light-emitting units be 100M, or 1000M, we can only lead to light detection SD
Signal, judges whether light unit leads to light, if logical light, is first that then 1000M detects light mouth whether link by light cell location
On, if illustrating on link that light unit is gigabit, if the not upper explanation light mouth of link is 100,000,000.Then light mouth is configured to
100000000.
2, when light mouth switches between 100,000,000 and gigabit, can sometimes can not go up by link, this problem is later by configuring
First giving optical module power-off before light mouth speed, configuration has been got well rear powering on to module and has been solved.This is also technological difficulties.
3, our scheme can also realize a function, if what our transceiver connect above is the 1*9 light list of gigabit
Unit, can connect use with the light unit of the 100000000 of other machine and gigabit, and client can use the optical mode of 100,000,000 now
Block comes cost-effective, can directly upgrade to the equipment of gigabit light later, it is not necessary to move our transceiver.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
