Bidirectional SFP+ modules - What you need to know to implement them

thank you! nice and clear

Good video, thank you !

Great video!!

Thanks for the video! I'm hoping to run fiber optic to a detached garage about 250 feet from my house. I have an existing buried conduit which is only 3/4" pvc meaning the interior diameter is only about 1/2 inch. Fortunately the run of pipe is completely straight with no bends. I was thinking a simplex single mode fiber with single LC connector was my best shot of getting the cable through the conduit. Do you agree with that? I could use a long ethernet run as an alternative but I thought the fiber might be more reliable. Right now i'm using ethernet over power lines and it's not very reliable, it drops out for a few seconds several times a day. Also I just installed a TP-Link TL-SG2428 switch in the house with SFP ports hopefully that was the right thing and I would use these sfp modules: "10Gtek a Pair of 1.25G SFP Bidi Transceiver, 1000Base-BIDI SingleMode Simplex LC Fiber Module". Again, really appreciate the video, thank you so much.

Both alternatives are great due to the short distance you have ( less than 300 ft). On the other hand Optic fiber will provide you protection against close lightning strikes, which is very important in some areas. With appropriate tools you could guide your preterminated optic fiber cable with LC connectors, due to the straight conduit layout. Just make sure not to pull excessively the fiber. You can even wire a parallel electric cable so you can centralize a UPS and bring power from your main location. have a great day and good luck with your project.

What is more effective price-wise, which 10G sfp+ modules are cheaper in general: 1) Bidi LC 2) Bidi SC 3) dual strand LC? I'm thinking about replacing my old switches and building a core network on 10G fiber, and it's so puzzling, I have no idea what to choose... I sorted out that we'll be talking about multimode, as max distance is about 100m. I think short range links, dual strand LC are most common -> cheapest to get second hand, can that be right?

[@TechnologyMoments]

I would choose to go for most commercially available and ease of use as well as error free (manipulation wise of connectors) Regarding this , with OM3 and OM4 can give you the flexibility you want, in dual fiber configuration which will avoid confussion inherent to bidi modules. As you are not handling great distances that will be enough. Even if you choose to involve SFP28 backbones in your building for 25 gbps for 100 meter runs over OM4

I need to connect UniFi aggregator to sw-8-150 what is the best cable and card? I like the idea of a single pair split for two switches

[@TechnologyMoments]

Yes you're right and that may be very convenient in many situations. If your aggregation switch uses 10 Gbps use SFP+ modules compatible with Unifi however the tricky part here is that you need to match the wavelength at which one transmits with the other end at which that one receives. It is better you contact customer service for example at FS.com (www.fs.com/tech_support.html ) where they can guide you and see if it is possible to mix yours that way, as I have always seen that wavelengths used in bidi cables are different when using SFP and SFP+ modules, as your US8 will use SFP modules at 1 Gbps. Good luck with your project

[@kc0eks]

I'm using some of these, doubled the link group bandwidth without any new cable.

[@abrahamherzog7493]

that's a great video I was waiting for someone to make a video like this, about bi Direction sfp , if I have some questions where can I ask it? For example I need Sfp switches, what are a good price for small business or a home lab, on a budget ? Thanks in advance❤

[@TechnologyMoments]

Thanks for your feedback, same switches, same ports just bidi modules.

[@abrahamherzog7493]

@@TechnologyMoments what's switches is good and cheaply

[@BrianNaeem]

Just so you know those duplex fiber clips come apart, you dont need to cut them...

[@kickstartnetworking3347]

Hi, why when I test a bidi device it sends power through the rx wavelength, I mean, it is a TX/RX device but if I test both wavelength the power meter reads power in both.

[@TechnologyMoments]

Hi, the power meter will test the "power" at which it reads the signal the module is transmitting.

[@kickstartnetworking3347]

@@TechnologyMoments but it reads power over the RX wavelength, the questions is why is it sending power through the RX wavelength.

[@vbboyv]

Can I plug my fiber internet right into my computer and bypass the ONT from the service provider. Ethernet holding me back.

[@TechnologyMoments]

Your ONT is necessary as it is the one that authenticates with your ISP so that equipment is always going to be necessary. If your Ethernet is slow compared to your ISP's speed you may want to consider upgrading your equipment to gigabit ethernet. If you are surpassing the gigabit limit with your ISP, you must demand your ISP to give you a device with 2.5 GbE ports... also you must upgrade switches and cards to meet those specifications. Hope this helped. Take a look at this video we talk about that: kzbin.info/www/bejne/qJvIn3Wvbs9-Y80

In Germany we lucky to have a 10gib

[@ChickenPermissionOG]

they are so expensive though

[@TechnologyMoments]

Yes, for big deployments may be quite some investment in SFP modules, but, big saving in optic fiber. For smaller deployments very practical. Have a great one!
