Revision 1.4 7705ET - 1
1. OVERVIEW
The 7705ET Ethernet Fiber Transceiver provides an economical method of transmitting two 10BaseT
Ethernet channels or one 100Base-TX Ethernet channel over optical fiber. The converter is IEEE 802.3
10BASE-T and IEEE 802.3u 100BASE-TX compliant, mediates between a 10/100BASE-TX segment and
supports both full duplex and half-duplex operation. A pair of 7705ET transceivers permits full duplex
communication over a single optical fiber. Diagnostic LEDs provide indication of power, linkage and data
reception.
Features:
•Auto negotiation for 10/100 speeds, half/full duplex modes
•Built in Ethernet switch for complete isolation of each transmission end
•Link status monitoring indicators
•VistaLINK®enabled for remote monitoring and control
•Optical output available in 1310nm, 1550nm and up to sixteen CWDM wavelengths in the 1270nm to
1610nm range
•Supports multi-mode or single-mode fiber
•Fully hot-swappable from front of frame with no fiber or Ethernet channel disconnect required
•SC/PC, ST/PC or FC/PC connector options
Two versions of the 7705ET allow the user to choose the optimal price / performance to suit a particular
application. The “-F2” version is designed to receive and transmit on the same wavelength over two
different fibers and has the lowest insertion loss. This version can operate with Multi-mode (MM) or Single-
mode (SM) fiber. The standard version is designed to receive and transmit on the same wavelength over a
single fiber and can operate with SM fiber only. Each version of the 7705ET is available with a 1310 nm
FP laser output. (See section 3 for specification information):

2. INSTALLATION
The 7705ET comes with a companion rear plate that has two RJ-45 input connectors and one SC/PC
(shown), ST/PC or FC/PC optical connector. The 7705ET-F2 version comes with a companion rear plate
that has two RJ-45 input connectors and two SC/PC, ST/PC or FC/PC optical connectors. For information
on mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7705ET Rear panels
2.1. ETHERNET CONNECTIONS
The RJ-45 connectors on the rear panel are for connection to network devices (server, workstation, router
switch, etc.) with a 10/100BASE-TX port through a twisted pair cable. While both RJ-45 ports will auto-
negotiate between 10 and 100 Mb/sec, the fiber port runs at only 100 Mb/sec. This means that while both
RJ-45 ports can run at 100 Mb/sec at the same time, packets may be lost if both ports have a high traffic
load. Therefore we recommend that only one RJ-45 port be used if it is to run at 100 Mb/sec.
The 7705ET Ethernet Transceiver is designed for use with 10/100Base-TX twisted pair Ethernet cabling
systems. When connecting for 100Base-TX systems, category 5 UTP cable is required. The maximum
cable run between the Ethernet Fiber Transceiver and the supporting hub is 100 metres. Make the
network connection by plugging one end of the cable into the RJ-45 receptacle of the Ethernet Fiber
Transceiver and the other end into a port of the supporting hub.

7705ET - 4 Revision 1.4
When connecting the 7705ET to a hub or switch a “straight through” cable must be used. When
connecting the 7705ET to the Evertz 7700FC VistaLINK®Frame Controller, another 7705ET, or the
network interface card of a computer, a “crossover” cable must be used.

Table 2-1: Ethernet Connector Pin Definitions and Cable Wiring
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a carrier signal
to one another to maintain the link. The 7705ET rear panel is fitted with two LEDs on each RJ-45
connector to monitor the Ethernet connection on each port.
10/100: This Green LED is On when a 100Base-TX link is established. The LED is Off when
a 10Base-T link is established (the LINK LED is On) or if there is no link established
(the LINK LED is Off). This LED should show the same information as the
respective 10/100 LED on the card edge.
LN/ACT: This dual purpose Green LED indicates that the 7705ET has established a valid
link, and whether the 7705ET is sending or receiving data. The LED will be On
when the 7705ET has established a good link, providing a good indication that the
segment is wired correctly. The LED will BLINK when the 7705ET is sending or
receiving data. The LED will be Off if there is no valid connection.

2.2. OPTICAL CONNECTIONS
"The 7705ET modules are designed to work with single-mode or multi-mode optical
fiber depending on the version (FC, F2) ordered.
2.2.1. Single Fiber version (7705ET)
FIBER I/O: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical
input/output from the 7705ET. This connector should be connected to the matching
connector of another 7705ET module at the destination end with a suitable fiber optic cable.
The 7705ET version receives on wavelengths in the 1270 to 1610nm range, transmits on a
1310 nm wavelength and is designed to work with either single-mode or multi-mode fiber
optic cable.
"
In order to establish a valid link between a pair of single fiber 7705ET modules,
one module must be configured as ‘Address A’, and the other as ‘Address B’.
Selection of the correct address is achieved by setting jumper J6. See section 5.3.
2.2.2. Dual Fiber Version (7705ET-F2)
FIBER IN: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical input to
the 7705ET-F2. This connector should be connected to the FIBRE OUT connector of
another 7705ET-F2 module at the destination end with a suitable fiber optic cable. The
7705ET-F2 version receives on wavelengths in the 1270 to 1610nm range.
FIBER OUT: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical output
from the 7705ET-F2. This connector should be connected to the FIBRE IN connector of
another 7705ET-F2 module at the destination end with a suitable fiber optic cable. The
7705ET-F2 version transmits on a 1310 nm wavelength and is designed to work with either
single-mode or multi-mode fiber optic cable.
2.3. CARE AND HANDLING OF OPTICAL FIBER
2.3.1. 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 7705ET modules are Class I, with a maximum output power of 2mW.

7705ET - 6 Revision 1.4
2.3.2. 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. We recommend
that you maintain 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 fiber optic cable
see section 3 of the Fiber Optics System Design chapter of this manual.
