SECTION 1 – GENERAL & SAFETY INSTRUCTIONS
This product is designated for use in restricted locations. It is strongly advised that you always follow these safety
instructions to help ensure against injury to yourself and damage to your equipment.
åALWAYS read the product data sheet and the laser safety label before
powering the product. Note the operating wavelength, optical output power,
and safety classifications.
åIf safety goggles or other eye protection are used, be certain that the protection
is effective at the wavelength(s) emitted by the device under test BEFORE
applying power.
åALWAYS connect a fiber to the output of the device BEFORE power is applied.
Power should never be applied without an attached fiber output. If the device
has a fiber output, a connector should be attached that is connected to a
fiber. This ensures that all light is confined within the fiber waveguide, virtually
eliminating all potential hazard.
åNEVER look in the end of a fiber to see if light is coming out. NEVER! Most
fiber optic laser wavelengths (1310 nm and 1550 nm) are totally invisible to the
unaided eye and will cause permanent damage. Shorter wavelength lasers (e.g.
780 nm) are visible and are very damaging. Always use instruments, such as an
optical power meter, to verify light output.
åNEVER, NEVER, NEVER look into the end of a fiber on a power device with
1.2 LASER SAFETY PROCEDURES
ANY sort of magnifying device. This includes microscopes, eye loupes, and
magnifying glasses. This WILL cause permanent, irreversible burn on your
retina.
åALWAYS double check that power is disconnected before using such devices. If
possible, completely disconnect the unit from any power source.
åIf you have questions about laser safety procedures, please call Blonder Tongue
before powering your product.
åDo not attempt to service the unit yourself, as opening or removing covers may
expose you to dangerous voltage and will void the warranty. Refer all servicing
to authorized service personnel.
åUnplug the unit from the wall outlet and refer servicing to authorized service
personnel whenever the following occurs:
oThe power supply cord or plug is damaged;
oLiquid has been spilled, or objects have fallen into the unit;
oThe unit has been exposed to rain or water;
oThe unit has been dropped or the chassis has been damaged;
oThe unit exhibits a distinct change in performance.
1.1 SAFETY PRECAUTIONS
åThe optical emissions from the units are laser-based Class IIIb, and may present eye hazards if improperly used. NEVER USE ANY KIND OF OPTICAL INSTRUMENT
TO VIEW THE OPTICAL OUTPUT OF THE UNIT.
åAs always, be careful when working with optical fibers. Fibers can cause painful injury if they penetrate the skin.

SECTION 6 - SYSTEM & SNMP MANAGEMENT
Simple Network Management Protocol (SNMP) is an Internet-standard protocol for collecting and organizing
information about managed devices on IP networks and for modifying that information to change device behavior.
Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and
more.
When the built-in RJ-45 Ethernet adapter is connected to an IP network, operators can remotely access device
settings via Telnet and SNMP for managing and monitoring the FIBT. This can be handled by a command line
interface (CLI). A MIB Browser can be used to access and read the settings and parameters. Readily available
SNMP software can provide a graphical user interface to performing these functions.
FIBT uses SNMP v2 and can be accessed through either the LAN adapter or the WAN adapter.
For best security practices, we recommend not connecting to the SNMP connectors if the operator is not going
to use SNMP to manage the device.
6.1 AGENT SETTINGS AND CONSOLE MANAGEMENT
Before using the SNMP features in FIBT, operators need to ensure it can be accessed. This may require adjusting
the IP network settings.
ADJUSTING THE DEFAULT IP NETWORK AND SNMP AGENT SETTINGS
The FIBT transmitter supports Telnet and web page management. When FIBT is connected with a computer
via RJ-45 (RS485), the computer IP address should be next to “192.168.1.20”. After both units are successfully
linked, the user can enter the IP address 192.168.1.20 into a web brower, such as Chrome.
After successful connection, the default user name and password are required.
Username = admin (case-sensitive)
Password = admin (case-sensitive)
6.2 WEB PAGE SETUP (RECOMMENDED)
1] Enter 192.168.1.20 in the browser address bar.
2] The default user name and password are admin. The successful landing page will have the following Blonder
Tongue header at the top.

SECTION 7 – CLEANING AND MAINTENANCE
7.1 CLEANING THE UNIT(S)
If the units need to be cleaned, avoid the use of all solvents and use low-pressure clean air to remove loose
dirt. Use low-pressure clean air to clear the connectors of any debris. Dirty or scratched connector end faces
will greatly reduce the unit’s performance. Foam-tipped swabs may be saturated with denatured alcohol* and
inserted into the optical port for cleaning. DO NOT INSERT A DRY SWAB INTO THE OPTICAL PORT AS THIS MAY
DAMAGE THE FIBER END FACE. Many ber optic installations experience degraded performance due to dirty
optical connector end faces. The following procedure should be used to properly clean the optical connector end
faces.
DIRECTIONS FOR CLEANING:
1) Fold the ssue twice so it is four layers thick.
2) Saturate the ssue with alcohol.
3) First clean the sides of the connector ferrule. Place the connector ferrule in the ssue, and apply pressure to the sides
of the ferrule. Rotate the ferrule several mes to remove all contaminaon from the ferrule sides.
4) Now move to a clean part of the ssue. Be sure it is sll saturated with alcohol, and it is sll four layers thick. Put the
ssue against the end of the connector ferrule. Put your ngernail against the ssue so that it is directly over the ferrule.
Now gently scrape the end of the connector unl it squeaks. It will sound like a crystal glass that has been rubbed when
it is wet.
5) Use the magnier to verify the quality of the cleaning. If it isn’t completely clean repeat the steps with a clean ssue.
6) Mate the connector immediately! Don’t let the connector lie around and collect dust before mang.
7) Air can be used to remove lint or loose dust from the port of a transmier or receiver to be mated with the connector.
Never insert any liquid into the ports.
7.2 CLEANING THE CONNECTOR(S)

▶Kimwipes®or any lens-grade, lint-free tissue. The type sold for eyeglasses work quite well.
▶Denatured Alcohol.
NOTE: Use only industrial grade 99% pure isopropyl alcohol. Commercially available isopropyl alcohol is for
medicinal use and is diluted with water and a light mineral oil. Industrial grade isopropyl alcohol should be
used exclusively.
▶30X Magnier.
▶Canned Dry Air.
7.3 CONNECTOR HANDLING
▶NEVER TOUCH THE FIBER END FACE OF THE CONNECTOR.
▶Connectors not in use should be covered over the ferrule by a plastic dust cap. It is important to note that the
inside of the ferrule dust caps contains a sticky gelatinous residue that is the by-product of the making of the
dust cap. This residue will remain on the ferrule end after the cap is removed. Therefore it is critical that the
ferrule end be cleaned thoroughly BEFORE it is mated to the intended unit.

SECTION 8 – TROUBLESHOOTING
ERROR CONDITION LCD MESSAGE DISPLAY AUDIBLE ALARM
No LCD or LED display
after turning on the
p o w e r.
No input power or a problem
with the internal switching
power supply.
Check input AC voltage to the
power supply (100-240 VAC), if the
voltage is normal, usually the
cause is the internal switching
power supply. Contact Technical
Support.
After turning on power,
LCD monitor and LED
normal, but optical
output power low.
Check jumper quality Swap to a good test jumper
Contaminated optical active
connector or adapter
Clean contaminated ber active
connector adapter (Section 7)
Damaged ceramic ferrule in
adapter
Swap the damaged adapter
After connecting to
network, all carrier
channels have obvious
noise point.
Low received optical power,
causing poor C/N.
Clean ber active connector or
adapter (Section 7)
RF input level too low for
sufcient laser modulation
Check RF input levels to
transmitter. (15-25 dBmV)
System link path C/N too
low.
Check link loss
Back-reection from bad or
dirty optical connectors
Use only angled (SC/APC) optical
connectors or fusion splice where
necessary.
After connecting to
network, only some
carrier channels have a
degraded SNR
Some channels SNR too low Check the individual channel
signal C/N or SNR
Check the atness of the RF input
After connecting to the
network, some carrier
channels have obvious
ripple, beats, lines, or
distortions.
Optical input power to
receiver is too high
Check input power at optical
receiver and pad, if necessary
RF modulation is too high. Check the optical transmitter
modulation level parameter and
re-adjust if too high.
RF input drive to
transmitter is too high.
Make sure the RF input level is
within the range (15-25 dBmV)
