Product Details

Product Introduction:

Extending fiber optic return channel, and user can customize uplink and downlink frequency.
With flexiable RF upgrade function, it can online upgrade downlink frquency to 750/860/1000mhz.
Modular plug-in optical receiving module and 1310nm and 1550nm two window receiving PIN diode, and high sensitivity PIN could receive super-low optical power.
Built-in LED optical power indictor, which precisely disply input optical power.
GaAs amplifier technology, back-level double power amplifer output, high output level.
Excellent AGC function, when input optical power is -7~+2dBm, output level and CTB as well CSO have no change.
Built-in branch splitter and distribution splitter, user could insert branch or distribution slpitter to select output mode.
Output interface feed, 15A overcurrent, each interface has LED indicator.
With Modular structure, reverse transmission platform reserved. The reverse transmission module and duplex filter works once it plugs in.
There are many types of lasers for choose, such as FP, IFP, DFB, which used in different transmission net.
High efficiency switching power supply.
Multi-protection of power supply and effective lightning proof measurements ensures the security.
AL-Diecasting hosing.
With External power supply indicator, easy to maintain.
