OPTICAL TRANSMITTER

External Type  

● The external modulation technology has   no chirp effect, very low dispersion distortion, and has good characteristics   in the band, and the working bandwidth is 47~1000MHz.

● The predistortion system of RF signal   can accurately match the pre-distortion volume and the signal quality   according to the signal intensity and modulation amplitude.

● The narrow line width (1MHz), low noise,   DFB CW laser and LiNBo3 external modulator do signal modulation.

● RF gain is optional, AGC/MGC mode, OMI +   7dB range adjustable.

● 19-inch 1U high standard frame, the   front panel is embedded with LCD display. It can accurately display the work   parameters and fault information of the equipment, and is equipped with the   national standard II transponder, which can monitor the network management   through the network.

● Hot plug dual power supply, you can   choose DC48V or AC110V or AC220V.

OPTICAL AMPLIFIER

● Using erbium and ytterbium Co doped   double clad fiber technology

● The built-in low noise preamplifier   without EDFA cascade reduces the deterioration of CNR and MER greatly

● The output port is optional

● 1U:SC connector 4~16 ports optional; LC   connector 8~32 ports optional, WDM can be selected

● 2U:SC connector 16~64 ports optional; LC   connector 32~128 ports optional; optional WDM

● Low noise coefficient: 0dBm input <   5dB

● The perfect network management   interface, conforms to the SNMP network management protocol

● The server's mature dual power hot   backup structure and the intelligent temperature control system controlled by   microcomputer can effectively improve the system reliability

OPTICAL RECEIVER

● Highly linear optical to electrical   converter for use in FTTH applications

● Use a high gain, low distortion receiver   PD and low noise RF circuit to deliver high RF level output at lower optical   power, provide good CNR, CSO and CTB distortion specifications

● RF reach to 1000Mhz bandwidth

● Optional AGC Function: Automatic Gain   Control (AGC) circuits is to provide a relatively constant output amplitude   of CATV signals. Optical receiver built in AGC function to enable RF output   tolerance in 2dB even when optical input power various from -8dBm to 0dBm

● Optional Built-in WDM Function: The 1550   nm broadcast analog video signal can be delivered over P2MP GPON or GEPON   network by using WDM technology. The built-in WDM optical receiver has the   one optical input port and on PON output port. The optical input contains   downstream forward path CATV signals at 1550nm, downstream Ethernet data at   1490nm and upstream Ethernet data at 1310nm. The optical output passes the   1310nm and 1490nm signals. The 1550nm wavelength goes to a photodiode and is   amplified.
