Love it that product saved my backside.

Scary enough I did a pita retro job without testing it first. Of course it didn't work at first but the Oinkyo AVR I was using didn't have enough HDMI power output for the cable. Added an external power piece for 20 bucks and now the system is tits.

Hi All on the Celerity thread. I'd like to fill you all in on what's up in the world of fiber optic HDMI. Celerity is a different company than Rainbow Fish. Yes, the Celerity management and product development team did work together at Rainbow but the relationship with Rainbow ended earlier this year. Subsequently, Celerity was founded and a terrific new product has recently begun shipping. We cannot comment on Rainbow Fish's current activities or future plans.

Celerity features a number of new benefits: 1. Really small fiber optic plug on each end of the long length fiber optic cables. 2. Detachable HDMI connectors corresponding to the TX and RX ends of the fiber optics. This makes it really easy to prewire and then connect the components. 3. Audio Return Channel support 4. Plenum-rated cable. Surely you know the benefits of #3 & #4. On the matter of plenum, we get a few questions about "OFNP" so let me explain - It means Optical Fiber Non-conductive Plenum which in simple terms, is the spec description for a plenum-rated cable jacket that encompasses a cable which does not include any electrically conductive members. Celerity is all fiber optics - glass, no copper and therefore non-conductive. If you want to geek out on the details, you can search for the UL-910 rating and a heap of detail is there. For those of you using Celerity, thanks tons. For anyone with a question or problem, please reach Celerity tech support as noted on www.celeritytek.com or if you want to reach me directly, you can do that here or ay my email of you have it. Regards, Buzz Delano

Hey Buzz,

What kind of power requirements are needed from the USB to power the Celerity? We are going to be using about six runs of Celerity (ranging from 60' - 200') to go from different laptop stations in a conference room to a Zektor matrix which will then distribute the signal out to a few large displays and a projector. Since the Zektor has no USB to power the various Celerity runs, we were planning on using some sort of USB Hub as our power source back att he rack.... your thoughts on this?

Hi,

If I understand correctly, the Zektor matrix will have the Celerity cables on its outputs. All HDMI compliant output ports provide 5V power on Pin 18 of the HDMI Type A receptacle. This is how the TX (send/source) end of Celerity is powered. So, you are good to go out of the box. At the RX (receive/display) end, Celerity also needs power and it is drawn from an available USB port and therefore our RX detachable HDMI connector also includes a USB power cable. You can use a USB to AC adapter (like iPad, or iPhone) if no USB port is available to connect to nearby AC. While there is power at each end of Celerity, power is not transferred over the fiber - only optical signals carrying the HDMI information rides the glass. Can you tell us the Zektor model number so we can be familiar with it.

Ok.. maybe I am misunderstanding something. I thought Celerity only required USB/power at the RX side. Our Zektor MAtrix will have Celerity on the input side. We will have six laptop station throughout the conference room with Celerity runs back to a racked Zektor Matrix (Clarity Elite HD). Since I thought we only needed power at the Matrix (RX side of Celerity) we were going to use some sort of USB hub to power the six Celerity runs. These would all be inputs into the matrix. We firgured a USB hub will allow us to power all six runs with just one device / power supply.

The outputs will be a 70" Sharp, 90" Sharp, and an Optoma Projector. However, there are all going to be Zektor Baluns since we do not want to run any Celerity during construction (the laptop stations mentioned above all have pvc conduit to allow us to pull the Celerity through later).

I'm pretty sure buzz misunderstood that you are using celerity on the input side of matrix and not the output. Although he did state it is standard USB so USB hub that adheres to USB spec will be fine.

How for is the run?

Just wanted to update my feedback on this thread.

We have 4 of the plenum cables at the job I mentioned before. Now that everything is fired up, we have 1 cable that works 100%, that is sources go to an AVR, then the fiber optic cable from AVR to the Display.

1 Cable works from an AppleTV to the Display but when we run it through another AVR model from the same company as the 1st we get no picture.

2 Cables just do not work from AppleTV or PC direct to display.

I believe my boss is getting in contact with tech support to see if there is anything that can be done.

I just installed a 60 foot cable between a AVR 2312 and a new Samsung 55 inch smart TV.  It works fine except I noticed that you can confuse the ssid resulting in a no picture state.  on a couple of occasions I had to power cycle both the receiver and the display to get a picture.

If you unplug the cable from either the TV or the reciver while it is on and then plug it back in sometimes the picture wont come back. So you have to power cycle everything. I dont know why this happens. Sometimes if you power on the TV and then wait a while before you power on the receiver you get a no picture state.

I know we either discussed this here or in a training class a while ago. HDMI is not plug-n-play, I know some older Panasonic sets could have their HDMI ports fried if you plugged them in hot. I've made a rule of not plugging in any HDMI hot and have seen HDMI related problems go down.

Wait what? Pin19 is the plug+play pin for hot plug detect.

Do you have any more info from that training or link to where this was discussed, because if I am wrong I would like to read up on this stuff.

I just found that Rainbow Fish has moved to a new location:

I used the cable on a conference room project. I didn't want issues with baluns
on various laptops, so went with the fiber. Very small connector to pull thru 3/4 conduit. Worked perfectly.

Hi, we were told that the Celerity Cable is "UL-910 Plenum-rated",
and on the cable, it indeed says “Celerity E239937 OFNP”.

But on UL web site:

[Link: database.ul.com].
E239937&ccnshorttitle=Optical+Fiber+Cable&objid=1076677338&cfgid=1073741824&version=versionless&parent_id=1073991634&sequence=1
It is "Types OFN, OFNG, OFNR." not OFNP, we asked for explanation a few weeks ago, but got no respond.

Someone lied about the UL rating?

It is what UL search found using E239937

Here is the result:
