DS110DF1610: DS110DF1610FBE/NOPB

Part Number: DS110DF1610

Hello, We enconter a problem when we use DS110DF1610:

1. The test rate is 10.3125G, the swing of the optical module on BERT is 850mV

2. We configurured the Card with DS110DF1610, and the rate is 10.3125G and everything works OK.

3. When we use module A from vendor A, When we plugged out the fiber and plugged in several times, it works OK whenever how we operate, and it will lock again when the signal is recovered.

4. When we use module B from vendor B, When we plugged out the fiber and plugged in about 5 times, the DS110DF1610 may be loss of lock. and it can NOT lock again

5. When the module is Loss of Lock, we can return to Normal when we change the swing of the BERT from 850mV to 600mV.

7. We change the Channel Register address 0x8E bit[1:0] from 00~11, it can NOT be recovered. the default value we set is 10

8. Set 2F bit 0 to 1, it does not work

9. 0x31 bit6:5, we change from 00 to 11, it does not work, the default value we set is 10

Could you give me some advice on how to solve the problem?

  • Hi Chen,

    Can you share the model numbers / datasheet of each module used? I'm curious if there is any marginality between them that suggests why lower swing from BERT fixes lock case with module B.

    To clarify on steps (4-5), if you use a BERT swing of 600mV at the start, is there any issue with lock? Or does this only fix the case where lock was initially lost?

    Thank you,

    Evan
