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.


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.


Where can I purchase a correct USB-AC adapter?

What do the connector LEDs 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.


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 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 Celerity 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.
