3.1 Overview
KAYA Instruments’ CoaXPress Range Extender over Fiber (KY_FEXT)provides a high
resolution stream interface for distances of up to 10km over single-mode optic fiber and up to 300m
over multi-mode optic fiber. Optic fiber is electrically isolated, hence it does not radiate nor is it
susceptible to electromagnetic interference, also eliminates the problems associated with grounding.
The fiber cable is not easily tapped, providing more secure communication. The system is
constructed of two convertors, one on the camera side (KY_FEXT_D) and one on the frame grabber
side (KY_FEXT_H). The camera side converter can provide power to the camera over CoaXPress
link, while the host side converter can sink power from the frame grabber. The converters use
flexible SFP+ modules for optical connection that can be easily changed. The range extender is able
to provide a downlink of up to 6.25Gbps (CXP6) and uplink of 20.83Mbps per each link.
3.2 Features
CoaXPress V1.1 compatible
Both ends of CXP6 is supported with up to 6.25 Gbps downlink, 20.83 Mbps uplink
Extension for distances up to 10km with single-mode optic fiber and up to 300m with multi-
mode optic fiber
Bidirectional CoaXPress communication
Flexible SFP+ module for optic fiber connection
DIN 1.0/2.3 Connector for CoaXPress link
Plug and Play , no need to configure
Power over CoaXPress (PoCXP) support
0°C to 50°C operating environment temperature

4.1 External View of the KY_FEXT
Each KY_FEXT unit is housed in a compact, metal enclosure. Each unit has a power connector, 4
coax connectors, 4 SFP+ cages and a Mini USB Terminal interface, as shown in Figure 1.
Coax
connectors
Terminal
interface SFP+ connectors Power connector
Figure 1: KY_FEXT external view
Each of the 4 coax and SFP+ connector is paired with a status LED and there is a system status
LED (see Table 1 and Table 2 describing the LED’s behavior).
Each unit also has mount ears for an easy and secure installation on any flat surface.
4.2 Power supply
This device requires 24V power supply for proper function. The Host side of the extender is
compatible with PoCXP standard and therefore doesn’t require external power supply, once the
Frame Grabber supports this feature too.
At the Device side, external power supply must be used. Please, refer to Electrical specification
section of this document for exact Power Supply requirements.
Below is shown the power supply connector of the KY_FEXT unit. An optional power supply or
user selectable must be connected to this on the device side extender box.
Connect the positive wire from the power supply to the “+” connector, connect the GND pin of
connector to the ground wire and the negative wire to the “-“ connector, as seen in Figure 2.

In order to properly use the KY_FEXT system, the following steps must be taken for initial power up:
1. Make sure there is no dirt or any other foreign matter inside the SFP+ module, or blocking
any of the connectors.
2. Make sure that the male connectors on the SFP+ module will align with the female
connectors inside the cage.
3. Insert the module(s) into the KY_FEXT and close the locking mechanism (*).
4. Connect the fiber cables using one of the configurations available:

5. Connect the Coax cables in the right order, as shown in Figure 6, Figure 7 or Figure 8.
6. Connect the Power Adaptors to the 2 KY_FEXT units (connecting the power supply to the
KY_FEXT unit is optional; if the unit is connected to a frame grabber with a PoCXP option
available).
7. Turn the camera and the frame grabber on and start your application software.
(*) The KY_FEXT system supports the following SFP+ modules:
1. KY-SFP-10G31-10 –Allows of up to 10Km connection over single mode fiber cable
2. KY-SFP-10G85-3M –Allows of up to 300m connection over multi-mode fiber cable
Note: to remove the SFP+ module, first remove the fiber cable connected to it, then open the SFP+
module’s locking mechanism (see Figure 9 and Figure 10) and remove module.

NOTES :
1. Link 0 of the extender must always be connected as power and controls are delivered with this port
2. A Fiber connection and CoaXPress connection must be done to the same port number all over the way
from camera to frame grabber.
3. A fiber cable should match an SFP type. If a single mode SFP is used a single mode fiber (yellow)
should be attached to it. If a multi-mode SFP is used a multi-mode fiber (orange) should be attached.
4. On Fiber channel 0 both the TX and RX fiber cables must be connected. On channels 1 through 3 only
one fiber cable should be connected. This cable is connected between TX output (Marked with TX or
Arrow outwards the SFP) on device unit and RX input (Marked with RX or Arrow inwards the SFP) on
host unit.

5.2 Bidirectional (BIDI) SFP option
This option allows reducing one fiber optic cable from the system. The total required number of
cables will be as number of CoaxPress cables. For example 4 link cameras will require 4 fiber
cables.
The KY_FEXT bidirectional system supports the following SFP+ modules simultaneously:
1. KY-BSFP-10G33-10 and KY-BSFP-10G23-10 –Allows of up to 10Km bidirectional connection
over single fiber cable.
In this option the SFP in link 0 is replaced by bidirectional (BIDI) SFP that transmits and receives
on the same fiber cable. Example connection for four link camera is described in Figure 11.

5.3 CWDM Option
In CWDM each optical SFP module operates at different wavelength and then an optical
multiplexer is used to mix all the signals into a single fiber. In this mode the number of cables
required in the infrastructure can be reduced from 5 down to two cables or even single cable. The
CWDM also can be used to use the CoaXPress over existing infrastructure, sharing the same fiber
cables with other applications.
Two available CWDM modes (for single or dual fibers) are described in Figure 12 and Figure 13.
For assignment of CWDM wavelengths please contact KAYA Instruments representative.

6.1 Terminal control
A Mini USB port is available for individual link & general information status and firmware update.
The port uses a Silabs CP2101 chip. A driver from the Silabs website might have to be installed on
certain PCs to gain access to the terminal port. Free supporting driver can be found at:
http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx
After driver installation and USB connection is acquired a serial emulated terminal (i.e. Tera Term
use is recommended) can be used with the following configurations, described in Table 3:

6.2 Firmware update
1. The extender supports firmware update via USB using a serial emulated terminal. To initiate
firmware update the following steps should be taken:
2. Connect the USB cable to the extender and acquire connection using Silabs drivers (drivers
need to be downloaded manually if an automatic download isn’t initiated).
3. Open serial emulated terminal (usage of Tera Term terminal is recommended) and set serial
communication protocol as described in Table 3.
4. In the terminal window type “status” followed by carriage return and checks the current
firmware version.
5. Choose the firmware update option by entering “firmware” followed by carriage return and
wait for the following message: "Now starting firmware update, please start file transfer
using XMODEM:"
6. At this point all the LEDs will turn off and the “System status LED” will slow pulse orange
indicating the extender is ready to receive the firmware binary file. Under “File” tab use the
terminal “transfer” capability using the XMODEM protocol to initiate the firmware update.
Choose “Send” and the firmware version: CXP_EXT_x_xx.rbf, when x_xx is the version
number.
7. If no firmware will be sent during 1 minute, or in case of an error the firmware update will
fail and return to previous operation mode.
8. A successful update will result in appropriate message and a reboot of the extender to new
firmware.
9. Check the firmware version by typing “status” followed by carriage return. Make sure that
the firmware version matches the version on the firmware update package supplied; that
would insure the success of the firmware update operation.
