Re: [802.3_DWDM] [EXTERNAL]: [802.3_DWDM] Presentation addressing Comment #83 - "Black Link"

Hi John, Steve and Peter,

 

One comment on the proposed remedy, Page 2. Bullet 1.

 

  • Term “”unidirectional”  This term is technically valid for black links which include optical amplifiers. Typically, isolators are used within optical amplifiers, which creates the uni-directional behavior.   Our use case for black link also includes implementations without optical amplifiers. In those use cases, the passive mux and demux filters, and cable plant, would support bi-directional optical carriers. Therefore, you might consider dropping the term ‘unidirectional” as one option, or clarification on this aspect in the text.

 

Regards,

 

John DeAndrea

Subject: [EXTERNAL]: [802.3_DWDM] Presentation addressing Comment #83 - "Black Link"

 

All,

At last week’s meeting we did not finish comment #83, which discussed the black link methodology. 

Please see the attached presentation that will be discussed on Thursday that seeks to close out Comment #83.

Please use the reflector to discuss the presentation to assist in reaching consensus and closing comment.

 

My thanks to my co-authors – Steve / Peter for helping to progress this.

 

Regards

 

John D’Ambrosia
