Frequently Asked Questions

Why is a Celerity Fiber Optic HDMI cable better than a copper cable?

Fiber optics work better for sending digital signals which include audio, video and data information. These signals travel faster and farther without degradation over fiber optics.


Do I need any extra items to use Celerity Fiber Optic cables?

No. there are no power adapters, extender boxes or other parts required.


Is USB power required at the TX (source) location?

It is optional and a rare instance when this is required. An HDMI source output connector provides 5V 50mA or greater power on the HDMI connector. Celerity TX draws power from this connection. However, in rare cases where insufficient power may be supplied, connecting the TX USB connector to a power source is required.


What type of USB-AC power adapter should be used when connecting the USB to AC power?

The required specification is 5V 1000mA, 50/60Hz 120-240VAC. An example of this is the USB-AC adapter for the Apple iPhone.

How do I provide power at the RX (display or projector) end of a Celerity fiber optic cable if there is no USB port available?

Attach a USB-AC adapter (spec: 5V 1A - Apple iPhone™ type) to the USB cable and connect the adapter to a nearby AC outlet..


What do the DFO HDMI cable LED lights indicate?

The blue LED at the TX connector will be on when the connector is plugged into a powered source. The blue LED on the RX connector will turn on when both the HDMI and the USB are connected to a powered display. If the HDMI is not connected to a TV/projector/display port, the blue LED on the RX connector won't turn on.


What is the bandwidth of the DFO HDMI cable and connectors?

18Gbps. The combination of Celerity's design, devices and pure fiber optic cable support 18Gbps or greater.


Can I add a copper HDMI cable to the TX or RX end of a Celerity fiber optic cable?

Celerity recommends that our cables are connected directly between a source and display for best results. Celerity cannot guarantee the performance and specifications when a copper HDMI cable is used with Celerity fiber optic cables.


Can I use a 90º HDMI female to male right angle adapter with a Celerity Fiber Optic HDMI cable?

Celerity recommends that our cables are connected directly between a source and display for best results. Celerity cannot guarantee the performance and specifications when an HDMI adapter or coupler is used with Celerity fiber optic cables.


Are Celerity Fiber Optic cables subject to interference?

No. Interference from appliances, wireless devices, computers and other home and business electronics will not affect Celerity Fiber Optics.


Are fiber optic cables durable?

Yes. They are actually quite strong. Inside the cable jacket is a woven layer of very strong yarn to provide durability and pulling strength. The yarn, known as "strength members", is made of Kevlar and protects the optical glass fibers.


What is the bend radius for Celerity fiber optic cables?

The bend radius is 5mm (0.2") which is approximately the diameter of a pencil.


I want to have a multi-room high definition video system in my home. Can I connect my sources, switchers and HDTVʼs with Celerity?

Yes, this is an ideal application for Celerity. Your Professional AV technician can easily hide the Celerity Detachable Fiber Optic HDMI cables in the walls of your home and connect all of the necessary components for your dream system. Now the picture and sound will be perfect at every location.


Iʼve heard that HDMI signals are complex and may not work at long distances. Is this true?

Celerity has solved these problems. We are experts in HDMI technology and have applied our knowledge to fiber optics to ensure that all HDMI signals are sent reliably up to 1000' away.


Why is the Celerity Fiber Optic HDMI “detachable?”

This is so that the Celerity fiber optic cable between components can be easily installed in tight, hidden spaces and in conduit when required. The detachable HDMI connector is easily attached to the miniature fiber optic plug after pre-wiring.


What is Audio Return Channel (ARC)?

ARC is a convenient feature that allows an HDTV to send its audio signal to an AV receiver without the need for an additional cable so that the sound can be heard on the loudspeakers in the room.
