Revision 1.1 7707GPS-DT - 1
1. OVERVIEW
The 7707GPS-DT GPS Data Transmitter provides an economical method of transmitting two Trimble
Accutime GPS data signals over a dual fiber optic link for communication with the 5600MSC Master Sync
and Clock Generator or 5010-GPSII. The 7707GPS-DT Data Transmitter facilitates conversion of dual
GPS data signals to a fiber optics signal for transmission. The 7707GPS-DT and 7707GPS-DR GPS Data
cards permit bi-directional data transmission of two Accutime 2000 Smart Antenna’s over distances up to
2 Km, with minimal latency.
The dual fiber configuration is designed to transmit and receive over separate fibers. The optical outputs of
the 7707GPS-DT and 7707GPS-DR are available in 1310nm and 1550nm wavelengths.
The 7707GPS-DT occupies a single card slot and can be housed in a 1RU Multiframe that will hold up to 3
modules, a 3RU Multiframe that will hold up to 15 modules, or a standalone enclosure which will hold 1
module.
Features:
•Transports GPS data signals from two Trimble Accutime 2000 Smart Antenna's simultaneously
•Allows user to run 1 or 2 Accutime 2000 GPS heads for primary and redundant links
•GPS power at +17V DC with built-in current limiting
•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 or 1550nm provides a 2km transmission distance of GPS
signal data
•Low latency
•Supports with multi-mode and single-mode fiber optic cable
•SC/PC, ST/PC, or FC/PC fiber connector options
•Fully hot swappable from front of frame
•VistaLINK

2. INSTALLATION
The 7707GPS-DT 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 the 7700FR chapter section 3. The
following diagram shows four rear plate options.

2.1. OPTICAL CONNECTIONS
2.2. 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 7707GPS-DR-F2 module at the destination end with a suitable fiber
optic cable. The dual fiber 7707GPS-DT-F2 versions receive on wavelengths 1310nm
and 1550nm.
FIBER OUT: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical output
from the module. This optical output is available in 1310nm and 1550nm wavelengths.
This connector should be connected to the FIBER IN connector of a matching dual fiber
7707GPS-DR-F2 module at the destination end with a suitable fiber optic cable. The dual
fiber 7707GPS-DT-F2 version transmits on the wavelength marked on the rear panel and
are designed to work with either single-mode or multi-mode fiber optic cable.
2.3. SIGNAL CONNECTIONS
GPS DATA: The GPS data is transmitted from the Accutime GPS head to the 7707GPS-DT via 100’
cable which is ordered with the 7707GPS-DT and 7707GPS-DR cards. Part number and
description for the cable is WA-T76-100' IF cable for 5600MSC, GPSII and 7707GPS-DT.

2.4. CARE AND HANDLING OF OPTICAL FIBER
2.4.1. Safety
!
Never look directly into an optical fiber. Non-reversible damage to the eye can occur
in a matter of milliseconds.
The laser modules used in the Evertz fiber optic modules are Class I, with a maximum output power of
2mW, and a wavelength of 1310nm or 1270 to 1610nm.
2.4.2. Handling and Connecting Fibers
 Never touch the end face of an optical fiber.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that the user maintains a minimum bending radius of 3 cm to avoid fiber-bending loss that
will decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come
with cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in
the frame that does not have a suitable I/O module. For further information about care and handling of the
fiber optic cable see section 3 of the Fiber Optics System Design chapter of this manual.

4. CARD-EDGE MONITORING AND CONTROL
The 7707GPS-DT has four LED status indicators and a 4-digit dot-matrix display on the front card-edge to
show operational status of the card at a glance. The card-edge pushbutton and toggle switch are used to
select various indications to the dot-matrix display and LED’s. Figure 4-1 shows the locations of the
indicators and pushbutton.

4.1. STATUS INDICATOR LEDS
LOCAL FAULT: This red LED indicates poor module health. Three conditions could cause this fault
indication to be active: A link with a companion 7707GPS-DR has not been
achieved, operation of the output laser is erroneous, or if a card power fault exists
(i.e. a blown fuse). The LOCAL FAULT indication can also be reported to the frame
by setting the FRAME STATUS jumper.
MODULE OK: This green LED indicates good module health. It will be on while a link is maintained
with a companion 7707GPS-DR, the output laser is operating properly, and the card
power is good.
LED1 – Green GPSA LED will light when GPS timing pulses are detected coming from
GPS port A.
LED2 – Green GPSB LED will light when GPS timing pulses are detected coming from
GPS port B.
LED3 – Red PWRA LED will light when a power fault has been detected on GPS port A.
