Fiber Optic HDMI Cable: (C-FOHM/FOHM (1.3))
The Fiber Optic HDMI Male
Congratulations on purchasing your Fiber Optic HDMI Male Cable. It is fully compatible with both HDMI
and DVI, and is ideal for home theater systems, medical and military digital display systems, as well as
conference rooms and stadiums. This cable is available at lengths of 33ft (10m), 66ft (20m), 98ft (30m),
164ft (50m), and 328ft (100m). It comes with this user manual and a +5V AC/DC power adapter.
Cable is a digital highquality graphics interface
between an HDMI source
(for example, a DVD
player) and an HDMI
acceptor (for example, an
LCD TV). It consists of a
transmitter (Tx) module
and a receiver (Rx)
module, connected by
multi-channel optic
distribution cables with
male HDMI connectors at
each end.
It transmits both the graphic signal and
display information (DDC/HDCP). It offers
DDC/HDCP interconnection and power
management via copper wire and R,G,B,Clk
TMDS graphic data over 4 multi-mode fibers.
Features
The Kramer Fiber Optic HDMI Male Cable (C-FOHM/FOHM (1.3)):
Supports all HD standards up to 1080p, and all VESA resolutions up to WUXGA (1920x1200),
at 60Hz refresh rate with 1 pixel/clock mode
Is a hybrid cable with four multi-mode fibers cables for the HDMI interface and embedded
copper wires to support the DDC2B/HDCP, Hot Plug Detect and power management
Can use either +5Vinternal power supplied via the HDMI / DVI graphic source, or from the
external +5V power adapter
Requires no software installation
Connecting the Fiber Optic HDMI Cable
Unpack the equipment carefully and save the box and packaging materials for possible future shipment.
To connect the Fiber Optic HDMI Male Cable, as the example above shows, do the following:
1. Connect the HDMI Tx connector of the Optical HDMI Cable to the HDMI source (for example, a
DVD player), without powering up the source. Note that the HDMI / DVI multimedia system or
graphic card must support the maximum graphic resolution of the acceptor that is to be connected.
Also, do not connect any intermediate cable or adapter between them as this may cause
deterioration in signal
2. Plug the +5V
power adapter
to the Tx
module power
socket and
connect the
adapter to the
mains
electricity.
transmission performance.
After connecting the system, and
confirming that it works, you can try
to disconnect the power adapter. If
the system still works you do not
need the power adapter. If it does
not work, reconnect the power
adapter (see step 4 for further
explanation).
3. Connect the HDMI Rx connector of the Optical HDMI Cable to the HDMI acceptor (for example,
an LCD TV).
Do not connect any intermediate cable or adapter between them (this may result in a deteriorated
signal
transmission performance).
4. Switch ON the power on each device (in this case, on the DVD player and on the LCD TV). The
Fiber Optic HDMI Male Cable uses the +5V internal power supplied through an HDMI pin (#18) /
DVI pin (#14) from the graphic source. When that +5V A/V source power is insufficient or nonexistent, connect the external AC/DC adapter to power the Tx/Rx modules. If the graphic source
can provide 500mA of +5V to pin 18, this external AC/DC adapter is unnecessary. (The +5V
power adapter can be plugged into the Tx module even when the Fiber Optic HDMI Male Cable
receives sufficient power from the HDMI source). In most cases, HDMI sources can supply
sufficient DC power to the two modules.
Avoiding Pitfalls using the Fiber Optic HDMI Cable
Be sure that the Fiber Optic HDMI Male Cable is stored and used away from liquid or dirt.
Handle the cable carefully. This is a fiber optic cable!! Rough handling may break the
cable/connections.
If the screen is distorted or displays noise, disconnect and reconnect the Fiber Optic HDMI Male Cable.
If the display device shows only a black screen, we recommend the following:
Be sure that the HDMI ports are firmly plugged into the HDMI source and the HDMI display
device, and that the correct Tx and Rx parts plug into the HDMI source / display device,
respectively
Check if the HDMI source and HDMI display device are powered ON and properly booted
Reset the system by unplugging and then replugging in the Tx HDMI port or Rx HDMI port, or
by unplugging and then replugging in the power cord plug of the Tx module
