Product overview
With the development of CATV fiber optic networks, from pure uni-directional CATV signal transmission to bi-directional, it develops into triple-play step by step. This is realized by fiber access with EPON, GPON networks. In 1550nm system, it has been a huge topic for the network operators how to inter-cut local individualized program and VAD service without investing high expense.
OPT-1550I-W optical transmitter, build-in WDM, the inter-cut signal will be multiplexed with main optical signal. Low-input design ensures excellent system CNR when optical power of main line is within the range +10~0dBm. Meanwhile, it is equipped with wavelength adjustable function which can avoid interference between main line signal and inter-cut signal caused by same frequency.
 
Features
1) High quality: With APC and laser thermoelectricity cooling circuit design, ensures the optimum performance and long life of the lasers
2) Flexibility: Build-in wavelength adjustable function, AGC function for RF part, RF level can be calculated according to the channel numbers inter-cut. Build-in VOA (variable optical attenuator) that effectively solves the adaption problem between inter-cut signal and main line signal and makes the adjustment simple.
3) Reliability: The 19 "1U standard rack, built-in high-performance switching power supply, it can work at 85~265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling automatic temperature control.
4) Intuition: Laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.
5) Network management (Optional): RS232 port for local management and monitoring, RJ45 port for remote control and management.
6) Pluggable power supply: Dual pluggable PSU, easy for exchange and work as redundancy.
