DW-ORA FTTH special optical receiver is designed to deal with FTTH fiber to the subscriber network
structure and launch products, light AGC control characteristic, output settings, optical power input ( - 7 ~ + 2
dBm ), output level is maintained substantially constant, CTB / CSO basically unchanged, machine reserved
for data communication interface, convenient and network management responder connection, access
network management system, digital display parameters, so that the engineering debugging more convenient,
high tensile aluminum alloy shell ( waterproof ), good shielding effect, more stable performance, highly
cost-effective, can be widely used in HFC broadband integrated information network, can be used for fiber to
the building, making the network more simplicity, lower cost, is the mainstream model of constructing CATV
network.

номер детали：DW-EDFA55PA Просмотров：61
DW-EDFA55PA is a most practical adjustable power amplifier, this machine adopt international famous
brand of the pump laser and the United States OFS erbium doped fiber, has low noise, saturated output
power, improve the reliability of the APC, ACC, ATC control and good ventilation and heat dissipation design,
to ensure the pump laser and the whole life a stable job, through the front panel buttons to adjust the output
optical power, regulating range every 0.1dBm, 3.0dBm down. The input optical signal is lost, the laser
automatic closing, the pump laser itself play a good role in the protection, applicable to the central office,
branch and line relay, can also be used for other optical fiber communication network, CATV system is the
most commonly used, the most dosage is a fiber amplifier. This machine is equipped with a microprocessor
software, has a laser monitoring, digital display, fault alarm, network management and other functions, once
the machine working parameters deviate from the software set the permission scope, the flashing red lights,
warning.

DW-EDFA55O The wild type optical fiber amplifier can use 220V or 60V AC and DC three 48V power
supply mode, is suitable for field installation. Because it does not need the room, completely solve some
outlying areas to build indoor room engineering problem. Cable route can take a shortcut, convenience for
engineering design and construction, greatly reducing the network construction cost, maintenance cost and
operation cost. Outdoor optical amplifier technology index and the same rules of the interior the same model,
built in large power electronic hot and cold, so that the equipment can work at - 40 DEG C to 60 DEG C in
field environment. This machine adopts the large cast aluminum shell, switching power supply with high
performance, advanced lightning protection system, to ensure that the equipment can work stably for a long
time in the wild environment.
