Hi Thanks for the very informative video. I want to use media converter to isolate my audio equipment from electrical noise. With the TP link MC220L which SFP module and fibre cable should be used? I live in Australia. Thanks.
For your information, this media converter is compatible with both multi-mode/single-mode SFP module, and it can extend fiber distance up to 0.5km using multi-mode fiber or up to 10km using single-mode fiber. If your primary concern is reducing electrical noise and interference, single-mode fiber is the better choice due to its superior noise immunity and performance over longer distances. Fastcabling has also developed different types of SFP modules and fiber cables. If you're interested, please free to consult our expert at support@fastcabling.com. SFP Modules: www.fastcabling.com/product-category/media-conversion/ Pre-terminated Fiber Optic Cable: www.fastcabling.com/product-category/pre-made-fiber-cable/
My ISP's router has a single fiber optic line and the ONT line port says SPF+ 10GB. I am assuming that the media converter I need is the SFP+ transceiver. I want to be able to connect the fiber optic line directly to a TP-Link XE-75 PRO. By cloning the MAC address of the router, I should be able to use my DECO-XE75 PRO correct? The ISP's router is ADTRAN and the ISP has locked down the admin page. I want to return the ISP's router and use if possible my TP-Link XE-75 PRO so that I have more control over advanced settings.
what about sfp+ dacs? i heard those are cheaper to connect from 1 switch to another within the same rack. also that multi mode is cheaper than single mode ya? and also sfp+ copper uses the most power and also gets hot. e.g. some switches can only handle up to 4 sfp+ copper transceivers tops. probly some stuff out of scope of this video subject but thought i'd mention them.
Thanks for your input. yes, the SFP+ DACS is cheaper, and multi-mode transceiver is cheaper for SFP+. That is why the multi-mode solution is popular in the data center. There is no much difference with the single-mode and multi-mode cable and SFP (1G) transceiver. The multi-mode cable has limited distance (about 550 meters). It is quite simple for single mode to reach 20KM.
@@Fastcabling i saw on youtube some other persons setup, they used optical fiber multi-mode to connect from 1 switch to another within the same rack. so i was wondering why they did that considering that sfp+ dac is cheaper for purchase not to mention uses less power than optical. in terms of power consumption lowest to highest, 1. DAC, 2. Fiber, 3. Copper yeah there those range differences, but for home lab user they wouldn't be requiring those ranges i think? maybe 30m at best? Would be interesting if you made a future video on this topic so people get the correct sfp+ especially for lowest cost so they don't end up overpaying for something overkill and expensive for no reason :}
Thank you for the informative video ! Do SFP modules support both UPC and APC fiber ? I'm asking because no SFP specification, that I came across, mentions this. Thanks
The SFP modules support simplex LC. You can find the specifications in the 'Resources' section of the product page. www.fastcabling.com/wp-content/uploads/2022/08/ds-5976-84-BiDi-SFP-Fiber-Modules.pdf
Thanks for the prompt response ! What I was referring to, was the LC connector polishing. LCs have different polishes of the connector - UPC(Ultra Physical Contact) and APC(Angled Physical Contact). Since it's not mentioned in the specifications, does that mean that this is irrelevant for SFPs. Thanks
Can you elaborate more on the differences between all the options and compatibility between cable and module. Do modules need to be in a send/receive pair or a module can send/receive to the same kind of module?
The SFP transceivers determine the fiber optical types (single mode or multi-mode), connector types (LC SC ST)… If it is the BiDi transceivers that takes different wavelengths to transmit the signal, you need different send/receive because the laser generator are different. Otherwise, there is no difference.
@@Fastcabling so if the SFP uses a single LC connector cable and single mode, then the sender and receiver SFP must be different (matching pair), but if multimode, then they could potentially be the same?
Just out of curiosity, why do you only plug in 1 strand into the SFP, and leave the other strand loose? Wouldn't that make the connection a simplex/1-way connection? For example, if I was connecting an antenna to a router with 2 strand os2 singlemode cable, with a transceiver on the antenna and the router, should both strands be plugged into the Tx/Rx ports accordingly? (i.e. the Tx port from the antenna side goes into the Rx port of the router side and vice versa?) Im still new to this and trying to figure it out, thanks for the videos though, short and simple.
It is the BiDi transceiver you saw in the video. The BiDi transceiver take different wavelengths to transmit and receive data. Single strand will be enough to carry up to 10G speed. The additional strand cable could work as backup or channel aggregation to double up the bandwidth.
@@Fastcabling Ohkay so it can Tx/Rx simultaneously on the same strand, I didn't realize that, I thought one strand was for Tx and one strand was for Rx. Thanks
You will need to choose Cisco compatible SFP transceivers. The SFP transceiver will determine the fiber optical cable and the connector type. As it is only Gigabit speed, there is no different between single and multi-mode. You don’t need single mode while the distance is beyond 550 meters. th-cam.com/video/y6fZdkQGTfk/w-d-xo.html
You might check the indicator on your switch or media converter. There is indicator which wil show whether the link is up or not. Otherwise, you can bring the switch back and test it with short patch cord. It will rule out a possible defect of the cable.
Not all SFP modules and connectors are inherently compatible. There are several types of fiber connectors used in networking, including LC, SC, ST, FC, and more. Most SFP modules used in networks today commonly support LC connectors but they can differ in design, supporting either simplex (single fiber) cables for one-way data transmission or duplex (dual fiber) cables for bi-directional data flow. So it's always recommended to check the compatibility and consult the module's specifications beforehand.
SFP transceivers can stop working due to various reasons: electrical surge/lightning strike, overheating, physical damage, and compatibility issues. To protect SFP transceivers from lightning strikes or electrical surges, consider using surge protectors or lightning arresters on your network equipment.
G-240W-B hi i have a quick question can i use the fiber port of G-240W-B router to make the router access point from the main router i mean by useing fiber cable between the tow router?
G-240W-B is an optical network terminal (ONT), a part of Passive Optic Networks (PON). The fiber port on the G-240W-B is designed to receive an optical fiber connection from your ISP. This port is typically not used for connecting to other routers in your network. Normally, routers or network terminals are interconnected using Ethernet cables. If your main objective is to extend or distribute your network using another router, you should do this via the Ethernet ports.
That depends on your specific network setup, equipment compatibility, distance requirements. It's recommended to select transceivers that match the data rate and protocol (e.g., Gigabit Ethernet, 10 Gigabit Ethernet) supported by your OLT and switch.
Hi greetings , In our premises we have been using aruba 5406 core switch and at outside idf ie less then two kilometer we are using Dlink DGS-f1100-10ps-e ( switch ) , how to know the compatible sfp for both aruba and dlink switch , could you pls suggest the compatible sfp module which should work with both switches , foc cable is singe mode ,waiting for your reply
Basically, there are two kind of SFP transceiver. The one comes with proprietary code, another type with generic code. The Cisco switch needs the SPF transceiver with proprietary type. I know D-link use generic, but not sure about Aruba. Once the code is being determined, now you can select connector to match the fiber optic cable - eg. LC or SC, single mode, BiDi for one strand connection.
I guess there is no afformtory answer. If the bandwidth 10G or less. Single mode fiber optical cable will be good. I personally prefer single mode. It achieve 10G up to 20km. The multi-mode has about 550meters. You will see more multi-mode deployment in the backbone inside the building or the datacenter. There is no need to concern the distance while we use single mode in most case.
Is there use for a SFP transceiver for a 2.5G home betwork? I'm going to do a total renovation of my home and I was thinking of cabling the home with Eth cat.7 cable which is capable of 10G. Any need for SFP+/fiber?
For most home networks, Cat 7 cabling will be more than sufficient to support current and near-future bandwidth needs, including 2.5G and up to 10G speeds, within the standard Ethernet range (up to 100 meters). But if your home layout requires cable runs longer than 100 meters or there are high-denisty areas with EMI, fiber would be a better choice. It's ideal for high-bandwidth requirements, such as a home lab, large-scale media production, or data-heavy work-from-home setups.
You could use a hybrid adapter that allows for proper matching between a UPC and APC connector without compromising signal integrity. These adapters are designed to account for the differences in angle and reflection.
The BiDi SFP modules support bi-directional data transmission, which means they can transmit and receive optical signals simultaneously on a single fiber strand by utilizing different wavelengths for each direction. Also, fiber optic cables don't necessarily come with 2 cables. The simplex fiber optic cable only consists of a single strand of optical fiber.
Hi i have a question, is fiber still supported when i have two different switches? For example one switch is a Cisco and the other one is a Dell or a Media Converter?
Yes, fiber optic connectivity is supported between switches from different manufacturers through the use of fiber optic cables and compatible transceivers or media converters. Ensure that both switches have compatible fiber optic interfaces. Common types include LC, SC, or MTP connectors. The choice of single-mode or multi-mode fiber depends on the distance and bandwidth requirements. Also the switches may require compatible fiber optic transceivers (also known as SFP or GBIC modules). Different manufacturers may use different transceiver models, so make sure the transceivers on both ends are compatible.
It takes 3 hours for the NVR to load, Two converter connect to Poe switch with cat6 cable. Can the cat6 cause the delay 2 of 16 NVR will load in time while the 3rd one takes hours to loads
I don’t tell it cause by the cable. You can’t feel the delay causing by the cables. You mentioned hours, I think there is some issue either with your setup or the devices. You can simply test the system with short patch cord to rule out the cause from the connection.
