Never look directly into an optical fiber. Non-reversible damage to the eye can

occur in a matter of milliseconds.



Do not hook up the 7707DT DWDM cards directly with a short fiber optic

cable. The 7707DT DWDM cards produce +7dBm of power, which will

damage the receiver if connected directly.

Revision 1.8 Page - 1

1. OVERVIEW

The 7707DT series Fiber Data Transceivers provide an economical method of transmitting multiple bi-

directional RS-232, RS-422, RS-485 data signals as well as Linear Time Code (LTC) over a single fiber

optic link. Another 7707DT Data Transceiver facilitates conversion back to RS-232, RS-422, RS-485 data

signals and LTC at the destination. The 7707DT-GPIO version provides additional channels of RS-232,

and General Purpose Input/Outputs (GPIO). A pair of 7707DT Data Transceivers permits bi-directional

data transmission over distances up to 50 Km, with minimum possible latency.

Two optical interface configurations allow the user to choose the optimal function /price /performance ratio

to suit a particular application. The standard configuration transmits and receives over a single fiber. The

dual fiber configuration is compatible with CWDM systems and is designed to transmit and receive over

separate fibers. The optical output of the 7707DT is available in 1310nm, 1550nm, or any one of up to

sixteen CWDM wavelengths.

Features:

•7707DT version transports four RS-422 or RS-485, three RS-232, and one LTC.

•7707DT-GPIO version transports four RS-422 or RS-485, eight RS-232, eight GPIO, one LTC.

•Selectable termination and failsafe bias settings for RS-422/485 data inputs.

•Selectable network timeouts for RS-485 accommodate twelve data rates.

•All configuration settings are controllable through the card-edge user interface, or VistaLINK®.

•Comprehensive signal and status monitoring via four-digit card-edge display, or VistaLINK®.

•Optical output wavelengths of 1310nm, 1550nm, and up to sixteen CWDM wavelengths

(ITU-T G.694.2 compliant).

•DWDM wavelengths also available (ITU-T G.694.1 compliant).

•Compatible with multi-mode and single-mode fiber (dual fiber version).

•SC/PC, ST/PC, or FC/PC fiber connector options.

•Fully hot swappable from front of frame.

•VistaLINK®enabled for remote monitoring and control when installed in 7700FR-C frame with

7700FC VistaLINK®Frame Controller.

2. INSTALLATION

The 7707DT series modules come with a companion rear plate that has multi-pin removable terminal

block connections, and an SC/PC (shown), ST/PC or FC/PC optical connector. For information on

mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter. The

following diagram shows four rear plate options.

2.1. OPTICAL CONNECTIONS

The 7707DT modules are designed to work with single-mode or multi-mode optical

fiber depending on the version ordered.

7707DT RS-232/422/485 Fiber Data Transceiver

Page - 4 Revision 1.8

2.1.1. Single Fiber Versions

FIBER I/O: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical

input/output from the 7707DT. This connector should be connected to the matching

connector of a matching single fiber 7707DT module at the destination end with a suitable

fiber optic cable.

All single fiber versions of the 7707DT are designed to work with single-mode fiber optic

cable. Single fiber 7707DT and 7707DT-GPIO versions use 1310nm wavelengths. Single

fiber 7707DT-W and 7707DT-GPIO-W versions use 1310nm or 1550nm wavelengths and

have their associated transmit wavelength marked on the rear panel. Configuration of the

CARD ID jumper is required for single-fiber 7707DT and 7707DT-GPIO versions only. Refer

to section 5.1 for details about the CARD ID jumper.

2.1.2. Standard Dual Fiber Version (-F2 version)

FIBER IN: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical input to the

module. This connector should be connected to the FIBER OUT connector of a matching

dual fiber 7707DT-F2 module at the destination end with a suitable fiber optic cable. The

dual fiber 7707DT-F2 versions receive on wavelengths in the 1270 to 1610nm range

accommodating standard, CWDM or DWDM transmission schemes.

FIBER OUT: There is one SC/PC (shown), ST/PC or FC/PC female connectors with the optical output

from the module. This optical output is available in 1310nm, 1550nm, and up to sixteen

CWDM wavelengths (ITU-T G.694.2 compliant). This connector should be connected to the

FIBER IN connector of a matching dual fiber 7707DT-F2 module at the destination end with

a suitable fiber optic cable. The dual fiber 7707DT-F2 versions transmit on the wavelength

marked on the rear panel and are designed to work with either single-mode fiber optic cable.

The dual fiber 7707DT-F2 versions are compatible with multi-mode fiber when connected

directly to a companion 7707DT-F2 module.
