1.0 PRODUCT SUMMARIZE
We are the well-known manufacture in analog externally modulated optical
transmitter in the world. GS8510, a kind of low cost 1550nm Externally Modulated
Optical transmitter, is specially designed for networking application of second-grade
service area. It is named as GS8510 second-grade service area 1550nm Externally
Modulated Optical Transmitter. GS8510 series Externally Modulated CATV
transmitter adopts low noise, narrow bandwidth, and continuous wave laser DFB
laser as its light source and adopts low cost single-output LiNbO3 external
modulator that is specially designed by JDS-U to modulate signal , which reduce the
cost of the transmitter largely. Based on a series of characterized optimization and
technical innovation, it can reach excellent system index with flatness ≤0.75dB
in-band 47~862MHz, 13dBm SBS, point to point >50Km, (0dBm receiving) CSO ≤
-65dB, CTB ≤-65dB, CNR ≥52dB. The whole unit is equipped with perfect RS232
communication interface, SNMP network management, 1+1 back-up power supply,
and casing temperature auto-control. All the optical port can be installed in the front
panel (The back panel is also available if needed).
2.0 INSTALLATION
2.1 Unpacking
Inspect the shipping boxes for any obvious damages.
Unpack the unit from all packaging boxes.
Inspect the appearance of the unit for any shipping damages.
Document and inform the shipping company and your local representative, if
any damage was found.
Save the shipping boxes and their inserts for future reshipment in case the
products need any upgrade or repair.
NOTE: When reship the products and send them back to the manufacturer,
the manufacturers will disclaim all the responsibility for the damage caused
by nonuse the original packaging.
2.2 Transmitter Mounting and Power Connection
1. Put the unit into a 19-inch wide rack or cabinet. Make sure to leave a
1.75-inch (about 4.5cm) space above and below the unit.
2. According to the design request, GS8510H series 1550nm optic
transmitter can work between 0°C~50°C（32°F~122°F）temperature range.
We recommend 25°C（77°F）environment temperature.
Humidity not bigger than 95%（under non-coagulation condition）. If necessary,
Page 1 of
7
the equipment should keep the suitable temperature & humidity in the
restrained scope. We recommend to operating in the environment without
dust.
3. The equipment can be powered by AC or steady voltage DC. In both of AC
& DC, AC is the chief power supply.
Request of power supply:
AC input 94-245VAC, 50-60Hz
DC input 36-60VDC, floating
Power consumption Maximum 50W
4. The DC power supply of the equipment must be the SELV supply stipulated
as CAN/CSA C22.2 No.950-95 standard.
5. The machine should have good grounding with grounding resistance＜4Ω.
According to the international standard, 220V plug in adopts tri-wire rule and
the middle wire is the grounding wire.
Before connecting circuit, please use big spec (#20AWG and more) electric
wire to connect the grounding screw on the bottom and the grounding frame.
When use DC input power supply, the equipment chassis must be grounding.
2.3 RF connection
Connect the RF cable & the connector on TX rear panel. RF connector is F type
plug. (F-Female/F-male Optional). The resistance is 75Ω.
2.4 Optic connection
1. Considering for protection & safety, all the fiber optic connector need
protective cover during transportation.
2. In order to ensure the insertion loss & return loss, the end-interface of
fiber optic connector should be cleaned. Please don’t dirty the connector. Even
the hair-like dust will affect the transmission quality. When take off the fiber
optic connector, please put on the protective cover.
3. Clean all fiber patch cords before connecting to the transmitter.
Cleaning Guidelines:
Fiber Patch cord connectors
- Remove the dust cap of the fiber connectors and wipe the fiber
connector tip with a dry lint-free cloth. Check if there are scratches or
debris on the connector surface by using a microscope (ie.100x or 200x).
- If no scratch or debris is found, the connector is ready for connection. If
scratches or debris is found, repeat the fiber patch cord connector
cleaning guidelines.
Fiber Bulkhead connectors
Page 2 of 7
- Compressed air may be used to clean fiber bulkhead connectors. Use
compressed air according to the following specifications at least:
- Non-residue, inert gas for precision dust removal
- Ultra-filtered to < 0.2 microns
- Recommended for optical systems
- Using compressed air as listed above, remove the bulkhead dust
cover and hold the can of compressed air about 6 inches away from
the connector. After spraying a few short bursts into the bulkhead, the
connector is clean and ready for connection.
- If compressed air is not available, the transmitter fiber bulkhead
connector may be cleaned by 2.5 mm alcohol sponge, or the
connector
plate may be removed to clean the internal fiber patch cords.
CAUTION: The use caution when handling fibers.
Do not exceed fiber manufacturer’s pulling tension or bend radius specifications
when removing fiber bulkhead connector plate.
- To remove the transmitter optical connector plate, remove the screw on the
far left of the optical plate and remove the screw on the far right of the optical
plate. Do not remove the screws on the optical bulkhead connector.
- Slowly remove the optical connector plate from the rear panel and
disconnect each fiber connector from the bulkhead mounted on the plate.
- Clean each fiber connector according to the fiber cleaning guidelines.
4. - Make sure the laser key switches on the front panel of the transmitter are in
the OFF position.
5. - Connect the fiber patch cord from the output of the transmitter to the optical
power meter.
6. - Turn the transmitter laser key switch to the ON position.
7. - Use the optical power meter to verify that the transmitter optical power
follows the specification.
8. - Turn the transmitter laser key switch to the OFF position.
