FTTH Fiber to the Home Network

Fiber to the home systems needs to be custom tailored to each individual application.Shenzhen Chuangmo Electronics manufactures custom RF over fiber systems for everything from small MDU's all the way up to whole cities. Typically with a Fiber to the Home system, the RF is on the 1550 nm band. Most GPON systems use the 1310 and 1490 bands for Ethernet communication. The reason that 1550 is reserved for the RF is that RF over fiber is particularly sensitive to loss. The RF optical signal needs to be much stronger than the corresponding GPON data signals. Optical channels in the 1550 nm band can be easily amplified with EDFA fiber amplifiers.  EDFA's are needed on any FTTx application with more than 32 endpoints. 

Shenzhen Chuangmo Electronics is able to design and deliver complete FTTx headend systems built to spec.let us know the number of endpoints and the length of fiber runs so that we will be able to help you.

For your better understanding, the following application drawing illustrates a standard CATV FTTH system for 4092 homes with an integrated GEPON system.  Such a system is scalable, allowing more subscribers to be added 500 at a time by incorporating more EDFA's.  The primary optical transmitter has an internal EDFA,which we also call it as RF IN EDFA(combined EDFA in 1550nm optical transmitter) that provides 8 identical optical outputs on 1550 nm.  Each output is 7 dBm, which is the ideal level to feed into the next EDFA. The primary EDFA each have an internal 16 way coupler that provides 16 optical outputs.  Each of these outputs is fed into a three way CWDM for integration with a GEPON system.  Each 16way coupler's output port has a corresponding OLT port for the GEPON system.  From here, each of the 16 outputs runs to a 32 way coupler for the final split.  The couplers allow each Primary EDFA to deliver service to 512 homes. 

Shenzhen Chuangmo Electronics can provide full range of Cable TV transmission equipment or FTTx intergration network equipment. as a experienced manufacturer, we provide wide range of products to meet operators requirement. from analog to digital signal or analog+digital signal, there are multiple choices available.
