INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MX2 / MXR2 series media converter. Please take a
few minutes to read these installation instructions in order to obtain the maximum performance from
this product.
FUNCTIONAL DESCRIPTION
The MX2 / MXR2 series combines a single fiber Ethernet port with two copper Ethernet ports. The
MX2-MM-FX-SC, MXR2-MM-FX-SC, MX2-SM-FX-SC, and MXR2-SM-FX-SC units allow transmission
speeds of 10 Mb/s or 100 Mb/s on each of the copper ports. The fiber port transmission speed is set at
100 Mb/s. The MX2 / MXR2 series converts the electronic Ethernet input into an optical output using a
1300 nm wavelength source. The MX2 / MXR2 series also converts an optical Ethernet input signal
returning on a separate fiber into an electronic Ethernet output using a 1300 nm wavelength detector.
The MX2-MM-FX-SC and MXR2-MM-FX-SC units operate on 50 um or 62.5 um multimode fiber with a
maximum distance of 2 Km. The MX2-SM-FX-SC and MXR2-SM-FX-SC units operate on 9 um
singlemode fiber with a maximum distance of 20 Km. Refer to the data sheets for detailed performance
specifications.
The MX2 / MXR2 series is configured to auto negotiate the copper ports to either 10Base-T or
100Base-TX Ethernet data at full or half duplex. The auto negotiate feature also selects the proper MDI
or MDIX interface. The MX2 / MXR2 series fiber port is set to 100Base-FX and is compatible with
IEEE802.3 100Base-FX standard products.
The availability of both a copper and a fiber port allows the MX2 / MXR2 series product to be used as a
straight through Ethernet media converter, changing an electronic data signal to a fiber optic data
signal.
This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation.
The detachable terminal block, RJ45 Ethernet data connector, and LED indicators provide for easy
installation and monitoring of data and dc power. The MX2 series is designed for mounting as a
modular stand alone unit. The MXR2 series is designed for rack mounting in the MXRC-1 subrack.
INSTALLATION
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD
CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.
Mount MX2 series units to a secure surface using #8 (3mm) hardware in four places. See the drawing
on the next page for mounting dimensions. Be sure to allow sufficient room for the required minimum
bend radius of the fiber cable used.
MXR2 series units slide into any open slot in the MXRC-1 subrack. Use a small screwdriver to screw
the top and bottom fasteners into place.
