Welcome friends once again to another featured product review.
Today’s product solves the issue of signal loss to your display when it’s located some
distance away from your streaming device or located at the other end of the room.
Presenting the Phoossno series certified fiber-optic HDMI cables.
Hi my name is Nick from the TV Box of channel, and some of you may, or may not have heard
of this type of cable, it uses, or the technology behind it.
There are also some of you, who have seen these cables, and cannot accept or understand
the difference compared to your standard HDMI cable.
In this review I’m going to explain and demonstrate the technology behind cables,
it uses, why it’s not for everyone, and you’ll get to decide whether this type of
cable is right for you.
So stay tuned, you have that after a word from today’s sponsor.
Today’s video is sponsored by Ugoos the best manufacturer of Android TV boxes in the
industry.
With their line of high quality models, Ugoos not only provides the highest standard of
quality hardware, but they are also the leading developers of Android TV Box firmware, that
is a second to none with features many have tried to replicate.
Their boxes are backed by regular firmware updates and good customer service.
You can find their boxes almost everywhere in major retail online stores, but for the
best prices, latest models, along with coupons, see the link in the description below is video.
The latest Ugoos AMB-plus will also be used for today’s demonstration.
And now back to the video.
Welcome back.
So these are Phoossno’s fiber-optic HDMI cables.
They come in lengths of 5m up to 20m for domestic use, but these cables are capable of much
greater lengths.
Currently on Amazon they come in 10, 15, and 20m, and later on 5m and 7.5m will be added.
So what’s the purpose of these cables and why are they important or any different from
a standard HDMI cable.
First of all, these cables are not for everyone, but can be used by anyone if they so desire.
These cables use fiber-optic strands to transmit signal from your streaming device to your
display using fiber-optic light technology.
For those of you out there in the IT and telecom field would instantly understand the technology
behind these cables, whereas those who are unfamiliar may brush this aside as hogwash.
So to better explain, I will start with what’s the difference in signal that passes through
a copper wire as opposed to a fiber-optic strand.
In your standard 6ft HDMI cable signal travels to your display via copper wires without issues
and can deliver signal containing 4K or 8K HDR, with features such as Dolby vision display,
Dolby Atmos, and DTS surround sound audio.
With your device sitting next to your TV or monitor, there is no issue whatsoever.
However, if you were to connect a projector let say that’s mounted to your ceiling,
or you have your streaming device located at the opposite end of the room, it would
require a much longer cable to deliver that signal.
This is where your problems begin because the question of bandwidth comes into play.
In order for 4K or 8K signal to successfully reach on your TV or monitor at those lengths,
the cable must have the required bandwidth to carry such loaded signal.
At short distances this is not an issue, however at distances in excess of 15 feet 4.5m the
problem of attenuation starts stepping in and the problem of reduced bandwidth and signal
loss becomes a factor.
So the longer the HDMI cable the higher the attenuation, hence resulting in poor signal
or total signal loss.
For 1080p attenuation is not as aggressive as it is with 4K or 8K display.
So for this very said reason fiber-optics were invented, and why it was used to create
these cables.
More than that, because of the nature of the transmission over fiber-optics, which is light
signal, it has a much higher bandwidth over 300 times that of the signal over copper wires.
This in turn allows a user to locate their display far away from their device, and enjoy
all the features the device has to offer with little to no signal loss whatsoever.
Due to this, the fiber-optic HDMI cable has features different to that of your copper
cable, both in manufacturing, handling, and usage.
Firstly in order for signal to transmit over a strand of fiber-optic glass, the light has
to be transmitted on one end using electronics, received at the other end using electronics,
and then sent to your display.
To achieve that, in each end of the cable there are electronics circuitry, one to transmit
the light and one to receive it.
This changes the way you connect your cable to your device, because the cable is not bi-directional,
meaning that you cannot connect the cable in any direction you want.
There is a source and a display, and these are clearly labeled on each end of the cable.
This is due to the type of fiber they are using which single mode fiber that transmits
light in one direction.
The other characteristic can become controversial to someone curious enough to cut open one
of these cables.
What they will find is that there are copper wires on the inside.
However these copper wires are not for transmission and serves two functions.
1.
The circuitry in each end of the cable needs power that comes from the HDMI port transmitting
the signal.
These copper wires provide power to the electronics for generating, receiving and converting of
the light signal.
2.
They also provide some some added strength to the cable.
Because fiber is literary glass it is flexible but very fragile, so even though they added
tubing and kevler to protect the cable from excessive bending or breaking , the copper
cables also assist with protecting from pull damage during routing.
So I hope that my explanation gave you a level of understanding of the science behind fiber-optic
signals, and for more information you can simply Google it.
But there is a greater concern behind fiber-optics, and for those in the technical field would
fully understand the importance of quality testing of your fiber-optic fusion splices
and patch cables for signal loss from bad splices and dust.
But how would one know whether the HDMI cable was properly spliced and is transmitting the
right amount of dB to your display without test equipment?.
This brings us to today’s sponsor and manufacturer of the Phoossno brand called Smartavlink.
Smartavlink was launched since 2009 and started to assemble Active optical fiber cables since
2013.
They specialize in photo-electric conversion cables, research and development, manufacturing,
and customized services.
Back in March this year in collaboration with Granite River Labs, a global leader in engineering
services and test solutions for connectivity and HDMI Forum Authorized Testing Center.
Announced that Smartavlink achieved full certification for their 10m and 20m Active Ultra High Speed
optical HDMI cables, making them the first manufacturer of optical HDMI cables to achieve
proper transmission at that those lengths.
But not only being the first manufacturer to obtain certification for those lengths,
they are also the only seller on Amazon and other retail stores that guarantee the quality
of their cables by providing a QR scan code that provides data on the cable you purchased,
and it also gives you a support form to report any issues you may have.
The environment at their factory in which these cables are manufactured is of the highest
standard to ensure that their products meet or exceed industry safety requirements, and
they conduct quality testing to deliver the highest quality cables to their customers.
So to demonstrate what I was speaking about earlier about this cable not being for everyone,
and for those that do need it why it’s important in relation to signal strength, bandwidth,
and attenuation.
I will perform a video HDR test using this 50ft 15.24m copper HDMI cable, and the 65ft
20m fiber-optic HDMI cable from Phoossno.
So what we have here is the fiber-optic cable actually being longer than the copper HDMI
cable.
And using the Ugoos AM6B-plus TV Box I will play an HDR video first using the copper cable
to see if it triggers the HDR display on the TV.
Then I’ll play the same video using the fiber-optic cable to see the difference.
So first just to be sure what we are looking for I connected a regular 4 feet 1m copper
HDMI cable, and on the TV we are looking for the HDR icon to appear once the movie starts
to play.
And there you have it, the HDR icon appears without issues, and it just goes to show that
if your device is sitting right next to your TV or display there is no need for a fiber-optic
cable.
Next this is the 50ft 15m copper cable and I’ll perform the same test.
Unfortunately when I connected the cable I could not get a display, but from past experience
I reconnected the 4 feet cable and set the box to 1080p resolution and then reconnected
the 50ft cable.
At 1080p resolution you can get a picture with the 50ft cable and a from this video
demonstration you can also get HDR display.
However when I tried to change the resolution to 4K at 60Hz, I could not get a display.
Which means this 50ft copper cable does not have the bandwidth to carry 4K or 8K signal.
And now with the 65ft 20m fiber-optic cable which is even longer than the copper cable
and I’ll perform the same test.
You must remember that you cannot connect the fiber-optic cable in any direction.
You must plug the end labeled source to your device, and the other end labeled display
you connect to your TV or monitor or else you will not get a picture.
And the results speak for itself, the video played smoothly, the display was of a high
quality, and the HDR icon was triggered during the video playback.
So this is definitely the cable you will want to use if your display is over 15 feet away
from your device and intend to view 4K HDR.
So viewers as a simple as this cable looks there is a heap of technology that goes into
creating these cables.
And for those who still don’t believe in fiber-optic HDMI, well I hope this video changes
your perspective.
In my personal use, I have three displays in various rooms that are connected to my
security camera’s DVR, and using an HDMI splitter I am able to get simultaneous feed
across each display using these cables with each display being approximately 10 - 15m
away from the DVR.
And with that said I have come to the end of this review.
After watching this video if you feel that you need this type of cable for your project,
or you need to ensure that you receive 4K or 8K picture quality to your display located
some distance away, then the Phoossno fiber-optic HDMI cables will be right for you.
