Construction of fiber-optic cable networks is not fully developed, and with the increase of the number of users, we always hope the optical fiber can extend a few kilometers longer on the basis of the original optical node network. The solution is usually assigned to the original optical node greater optical power; or directly to do allocation by passive optical node in order to save investment. Generally optical receiver can not get the ideal system indicators.
Based on existing network, neither change or increase optical power distribution nor its network structure, and to let new added optical node achieve good performance, adopting Yantai Yatai ultra-low optical power receiver can be a cost-effective solution to this problem.
Our optical receiver adopts international-advanced GaAs HBT integrated circuit technique, thus optical receiver has very low noise power. When receiving optical power is -6dBm, CNR still can be above 50 dB, so it can save transmitting optical power and this effect is more remarkable when receiving optical power is low.
Using the ultra low optical power receiver technology can extend the length of the optical fiber transmission with a relatively small investment and also can find a new method for construction of a large optical fiber network. On one hand, it saves on optical power and investments, on the other hand, the existing network infrastructure maintains.
Type A： AGC；Type B：AGC/MGC switching type；Type C：Universal type
When input power is -7dBm to +1dBm，optically controlled plate output level is：72dBuv.
Yatai adopts low noise processing circuit, better solves the problem of increasing of noise when input power is -7dBm. When input power is -7dBm to +1dBm, CRN、CTB and CSO all cater to national standard.
