China OEM Customized Tv Aerial Amplifier - ODN – 1218S FTTB Optical Receiver – Qianjin factory and manufacturers | Qianjin Detail:

ODN-1218S is a 1.2 GHz compact size two-way receiver for HFC, RFoG or RF overlay applications. It provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. There is an optical AGC function in forward path to ensure same RF output level in every building. It can be operated in RFoG (burst-mode) or HFC (continuous wave) mode. The upstream optical wavelength can be set as CWDM standard to realize OBI-free effectively.

Features

1. Supports 1.2 GHz RF pass band

2. One fiber with WDM for forward and return path

3. AGC optical input range of – 6 to + 1 dBm

4. 114 dBµV RF output level @1200 MHz

5. Plug-in diplexer, LPF and HPF enable migration toward DOCSIS 3.1 upstream

6. Digital code switches for all adjustments of attenuation and equalization 

7. 1310nm, 1550nm and CWDM DFB laser options for return transmitter

8. RF test points for forward and reverse path

9. MC jumper for laser status switch, installation easily

10. LED indicators for optical input, output and power

11. Surge protection (6kV) at RF output
