T3/E3 Standalone Module USER MANUAL
The iConverter T3/E3 media converter provides standard T3 (44.736Mbps) or E3
(34.368Mbps) coax to fiber conversion and can be used to connect to devices such
as PBXs, multiplexers, routers and video servers via fiber. T3/E3 media converters
operate in pairs, extending distances over fiber, which improves noise immunity, quality
of service, intrusion protection and network
security.
The T3/E3 supports Small Form Pluggable
(SFP) transceivers, enabling adaptability
to different fiber types, distances and
wavelengths, providing maximum flexibility
across a variety of network architectures
and topologies.
INSTALLATION PROCEDURE
1) Configure DIP-Switches
2) Install Standalone Module and Connect Cables
3) Verify Operation
1) CONFIGURE DIP-SWITCHES
FRONT PANEL DIP-SWITCHES
“FLB” - Fiber Loopback
This DIP-switch facilitates the testing of
the fiber cables. When the “FLB”
DIP-switch is in the UP position, it sets
the fiber port to a Local Fiber Loopback
Mode (Figure B) and the “FLB” LED is
turned on. When in this mode, data
received at the Fiber-In is forwarded to
the BNC-Out and the Fiber-Out. If no
data is received at Fiber-In, an AIS
pattern is transmitted out both BNC-Out
and Fiber-Out. By returning the
DIP-switch to the DOWN position, the
unit resumes normal operation.
Figure B: Fiber Loopback and DIP-Switch Settings
“CLB” - Coax Loopback
This DIP-switch facilitates the testing of the coax cables. When the “CLB” DIP-switch
is in the UP position, it sets the coax port to a Local Coax Loopback Mode (Figure C)
and the “CLB” LED is turned on. When in this mode, data received at the BNC-In is
and the Receive must attach to the Transmit.
d. Connect an appropriate multimode or single-mode fiber cable to the fiber port of
the installed module. It is important to ensure that the transmit (TX) is attached to
the receive side of the device at the other end and the receive (RX) is attached to
the transmit side. Single-fiber (SF) media converter models operate in pairs. The
TX wavelength must match the RX wavelength at the other end and the RX
wavelength must match the TX wavelength at the other end.
3) VERIFY OPERATION
Once the module has been installed and configured per steps 1 and 2, verify the
module is operational by viewing the LED indicators.
The Power LED indicates the module is receiving power.
The Fiber Optic link LED indicates the fiber optic connection has been established.
The Coax LED indicates a T3/E3 signal has been detected.
