612T, 612R 4K60 4:4:4 DP Tx/Rx over Extended-Reach Multi-Mode Fiber
Optic Cable
Congratulations on purchasing your Kramer 612T and 612R Plug and Play active 4K60 4:4:4 DP
Tx/Rx over Extended-Reach Multi-Mode (MM) Fiber Optic cable. 612T and 612R extend signals of
up to 4096x2160 @60Hz, over a distance of up to 200m (656ft) without signal scaling or data
compression, providing a maximum data rate of 21.6Gbps (5.4Gbps per lane). 612T and 612R are
easily and securely connected via a 2LC fiber connector and can be powered either from the USB
connector or from the DisplayPort interface (pin #20).

Installation
To install 612T and 612R:
1. Unpack the contents of the package with care.
We recommend that you save the original box and packaging materials for possible future
shipment.
2. Turn on the power to the DisplayPort source (for example, a laptop) and acceptor (for
example, a display).
3. Power the 612T and 612R:
• Connect the micro USB connector on each device to a USB cable (supplied).
• Connect the USB cable either to the wall-mount power adapter (supplied) and to the
mains, or to a USB port.
The POWER LED lights and the STATUS LED flashes three times.
Although the transmitter and receiver can be powered via pin #20 on the
DisplayPort interface, we recommend that you use the USB power adapters
on both sides.
4. Connect the two LC optical fibers between 612T and 612R.
Connect (A) to (A) and (B) to (B). Make sure that the duplex connectors are connected
properly.
The STATUS LED flashes.
Do not look directly into the LC connectors on the 612T (the transmitter side)
when it’s powered.
This product operates under LASER Class I, classified by CDRH/FDA for eye
safety.
We recommend that you avoid using intermediate cables or adapters. Using
them may affect the transmission quality.
5. Connect 612T to the DisplayPort on the source side and 612R on the acceptor side.
Make sure that the 612T is always connected to the source side and the
612R is connected to the acceptor side.
If you cannot connect the 612R directly to the display, we recommend that
you use the DisplayPort (M) to-(F) extension cable supplied with the package.
Once the system is connected the Status LEDs on both 612T and 612R flash.
Troubleshooting
If the display appears black:
• Check that the source and display devices are both switched on.
• Check that the power source adapters are properly connected on both sides.
• Make sure that both DisplayPort connector heads are fully plugged into the devices.
• Reset the system by disconnecting and then reconnecting the 612T or 612R, or by
disconnecting and then reconnecting the power adapters.
• Reboot the system.
If the image appears distorted and/or there is background noise:
• Go to the display properties and check the settings. Make sure that the resolution is set below
4096x2160 at a 60Hz refresh ratio to check if the graphic resolution is properly defined.
• Reset the system by disconnecting and then reconnecting the 612T or 612R, or by
disconnecting and then reconnecting the power adapters.
It is important to connect the devices correctly as marked: 612T to the source side and
612R to the acceptor side.
