[AusNOG] Transceiver for dark fiber.

Tue Aug 17 12:22:07 EST 2021

Yes our length is probably going to be a touch over 20km from Vocus so we used the 40km HP compatible optics and an attenuator

Also I am unsure who you are using but make sure you ask how they are going to hand it off

Be cautious of using long range transceivers (LR) for short range duties - you are pointing a very energetic LASER / LED towards a receiver that is expecting a lot of energy to be lost before arrival.
Transceivers do have a minimum length, or they will require an attenuator.

for eg:

Notice: When the long reach transceiver is used in short distance transmission, please matched with appropriate attenuator according to the table.

Cheers,

FS has been good here too. I think we’ve had one GLC-T and one 80km 8Gbps FC SFP fail out of 1000+ SFPs/AOCs/DACs that we’ve ordered. We used to order a spare for each model and DWDM colour we ordered but we mostly don’t bother with that now, since the Melbourne warehouse was setup and reliability has been high.

Their sales people are really helpful too and respond quickly. They get techs involved for anything they can’t answer themselves.

Cheers,
Scott.

Thanks all

FS certainly pops up top of Google Foo good SOE.

Will give them a go with the 40km units. Cheap really compared to the service cost. Good to hear some positive reports.

Hi Alex,
I've used plenty of FS.com transceivers.
For a 1G link, you might get away with a 10km optic, but better chances with https://www.fs.com/au/products/48929.html<https://aus01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fs.com%2Fau%2Fproducts%2F48929.html&data=04%7C01%7Cscott.mcinness%40datacom.com.au%7C5f871030a8a1402e0e5108d9611c00ed%7C866c7a4c8a594bd3ad9f8512a581efc0%7C0%7C0%7C637647595191458091%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=gvZJfxraCtDBTMFjPT%2F5J6%2FS5%2B%2BV8011jGgZvFKUzWI%3D&reserved=0>.
For a 10G link, again you might get away with a 10km, but a 40km doesn't cost much more - https://www.fs.com/au/products/48813.html<https://aus01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fs.com%2Fau%2Fproducts%2F48813.html&data=04%7C01%7Cscott.mcinness%40datacom.com.au%7C5f871030a8a1402e0e5108d9611c00ed%7C866c7a4c8a594bd3ad9f8512a581efc0%7C0%7C0%7C637647595191468083%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=udYQevOMrkdAzzTHjMraeRTfSPxw9pZkHN39Ft3GHcA%3D&reserved=0>.

Greetings.

Looking for recommendations for a SFP type Transceiver for 11km dark fibre Vocus service.

Anyone has any recommendations for what they have used successfully.
