Page 5 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 7707IT DWDM cards directly with a short fiber optic cable. The 7707IT DWDM cards produce +7dBm of power, which will damage the receiver if connected directly.

Page 7: Overview
The standard configuration transmits and receives over a single fiber. The dual fiber configuration is compatible with CWDM & DWDM systems and is designed to transmit and receive over separate fibers. The optical output of the 7707IT is available in 1310nm, 1550nm, CWDM & DWDM wavelengths.

Page 9: Installation
7707IT Multi-Channel Intercom Fiber Transceiver INSTALLATION The 7707IT 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.

CWDM wavelengths (ITU-T G.694.2 compliant). This connector should be connected to the FIBER IN connector of a matching dual fiber 7707IT-F2 module at the destination end with a suitable fiber optic cable. The dual fiber 7707IT-F2 versions transmit on the wavelength marked on the rear panel and are designed to work with either single-mode fiber optic cable.

7700 MultiFrame Manual 7707IT Multi-Channel Intercom Fiber Transceiver 2.2. SIGNAL CONNECTIONS Figure 2-2: Terminal Block Wiring Simultaneously insert a signal wire (28-18 AWG) and use a screwdriver to secure it into the block as shown in Figure 2-2. The screwdriver will push a tension clamp and will allow the insertion of the wire.

Triangular band: black Symbol: black 2.3.2. Assembly Assembly or repair of the laser sub-module is done only at Evertz facility and performed only by qualified Evertz technical personnel. 2.3.3. Labeling Certification and Identification labels are combined into one label, as there is not enough room on the product to place the label it is reproduced here in the manuals.
Page 16: Handling And Connecting Fibers
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 you maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will decrease the maximum attainable distance of the fiber cable.

Page 20: Card-Edge Monitoring And Control
CARD-EDGE MONITORING AND CONTROL The 7707IT has one LED status indicator per channel 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.
Page 21: Card-Edge Display And Controls
7700 MultiFrame Manual 7707IT Multi-Channel Intercom Fiber Transceiver 4.2. CARD-EDGE DISPLAY AND CONTROLS Additional signal and status monitoring is provided via the 4-digit dot-matrix display located at the card- edge. The card-edge pushbutton and toggle-switch are used to navigate through the display menu. Figure 4-2 provides a quick reference to the display menu structure.

Optical link established, no video input or laser (if equipped) problems. 4.2.2. Displaying the Optical Power The 7707IT can measure and display optical power over a range of –40 to +4dBm in 1dBm increments. Please heed the maximum optical input power specification for the specific product option you possess.
Page 24: Selecting An Interface Profile
Therefore, four types of call-signaling are present in the industry; two types for matrix, and two types for party-line. The 7707IT accommodates all of these via selection of an interface profile. This provides a user-friendly means of configuring the 7707IT for a specific application.
Page 25: Setting The Party-Line Audio Null Level (Future)
2. 4.2.5. Setting the Party-Line Audio Null Level (Future) This section applies only to installations using party-line type intercom systems. The 7707IT has a self- calibration capability for automatic null adjustment. This user-friendly feature is unique in the industry.
Page 26 The self-calibration feature of the 7707IT requires that all other intercom devices be connected and powered, but that none are actively being used to communicate audio. The 7707IT will apply an audio test signal to the system, and automatically adjust its null value for accurate cancellation. Other intercom devices will receive this test signal, but must not apply an output signal to the system.
Page 27: Setting The Analog Audio Detection Threshold
To change the audio detection threshold, select the CTRL menu item in CH01 to CH03 or menu level 1. The 7707IT allows an audio detection threshold to be set for CH08 each channel. Use the toggle switch to choose the channel for which you want to adjust the detection threshold.
Page 28: Selecting The Serial Data Termination
4.2.8. Selecting the Serial Data Termination To simplify installation, the 7707IT provides a selectable input termination of 110Ω for the balanced serial data signals. This termination should be active as required by the specific application, and common practice.
Page 29: Selecting The Serial Data Failsafe Bias
4.2.9. Selecting the Serial Data Failsafe Bias To simplify installation, the 7707IT provides a selectable failsafe bias for balanced serial data signals. This bias should be active as required by the specific application, and common practice. The failsafe bias will apply a differential +200mV bias to a properly designed RS-485 system while in the idle state.
Page 30: Selecting The Rs485 Serial Data Rate
To turn the failsafe bias on or off, select the CTRL menu item in menu level CH01 to CH03 or 1. The 7707IT allows a failsafe bias threshold to be set for each channel. CH08 Use the toggle switch to choose the channel for which you want to adjust BIAS the detection threshold.
Page 31 To set the RS485 serial data rate, select the CTRL menu item in menu level CH01 to CH03 or 1. The 7707IT allows the data rate to be configured differently for each CH08 channel. Use the toggle switch to choose the channel for which you want to RATE adjust the data rate.
Page 32: Global Control
7700 MultiFrame Manual 7707IT Multi-Channel Intercom Fiber Transceiver 4.2.11. Global Control CTRL To apply a profile to all channels select the CTRL menu item in menu level GLBL 1. Use the toggle switch to choose the Global Control option (GLBL) and PROF press the pushbutton to apply the displayed selection.
Page 33: General Purpose Inputs And Outputs
7707IT Multi-Channel Intercom Fiber Transceiver GENERAL PURPOSE INPUTS AND OUTPUTS The 7707IT provides the user with 2 General Purpose Inputs (GPI’s) and 2 General Purpose Outputs (GPO’s). Figure 5-1 shows the input and output circuitry. Refer to sections 3.4 and 3.5 for electrical specifications.
Page 34: Jumper Controls
To maintain a link between two companion 7707IT cards, the CARD ID jumper must be set differently on each. This is required to guarantee synchronization of data in either direction. CARD ID: To maintain a link between two 7707IT cards, set this jumper to position A on one card, and to position B on the other card.

® 7.5.1. Control Settings Through VistaLINK control, as illustrated in Figure 7-1, the 7707IT can be easily configured for different ® applications using the programmed profiles. Each channel is configurable as party-line or matrix, and to interface with the following industry-standard intercom systems.
Page 37: Profile Settings
7.5.1.1. Profile Settings There are three Interface Profiles available when using the 7707IT-3-F2. For the sake of brevity, only Interface Profile 1 will be discussed in the manual. The Interface Profile 1 drop down menu enables the user to choose from the following list of interface...

Page 39: Audio Gain Settings
7.5.2.1. Data Termination Status The 7707IT provides a selectable input termination of 110Ω for the balanced serial data signals. This termination should be active as required by the specific application, and common practice. For the sake of brevity, only Data Termination 1 will be discussed in the manual.
Page 40: Data Fail Safe Bias Status
7.5.2.2. Data Fail Safe Bias Status The 7707IT provides a selectable failsafe bias for balanced serial data signals. This bias should be active as required by the specific application, and common practice. The failsafe bias will apply a differential +200mV bias to a properly designed RS-485 system while in the idle state. As a protection feature, the failsafe bias will not become active unless the termination is also active for the respective channel.
