PON+CATV Single-fiber Transmission Solution

CATV1550 Full network transmission + GEPON or XGPON technology, build the city all-optical network transmission scheme is suitable for the development needs of wired broadband, GEPON or XGPON through low-cost WDM reuse in the 1550 cable TV optical transmission system, 1550 / 1490 / 1310 or 1550 / 1577 / 1270 three waves can share spectral channels, so as to build a competitive,relatively low cost wired broadband network to meet the present and future multiple business needs.

In the household scheme of single fiber transmission, the 1550nm optical signal and PON 1310nm / 1490nm or 1270nm / 1577nm optical signal in the optical transmission room through the EYDFA with FWDM to one optical port, each optical port has the CATV optical signal and PON optical signal, and then transmitted through the single fiber of ODN equipment at all levels to the client optical fiber network to the user's home after the user's optical network separation. Within the user's home, Equipment application planning can be configured early before according to different business requirements, CATV + network and wireless router have requirements can use our HSOS111762GNW equipment, 1GE + 1FE network port, 2*2 WIFI without routing, While watching CATV video programs; Alavailable HSGS10076W WDM optical Where the PON is connected with the ONU ring, This can both receive the CATV TV signal, Can also use the network at the same time; Adopt HSGS10076D filter type optical receiver for pure CATV service, It can filter out the PON wavelength, Receiving the CATV service.

Features of single-fiber transmission solutions:

1. Network management and maintenance are simple and convenient: Since the network architecture of three waves is end-to-end, it is convenient to manage user terminal devices. Operator managers can use our HFC network equipment management system to open or close remote business, fault location and maintenance operations.

2. Low cost of passive optical network: because radio and television signals and broadband data signals are transmitted on the same physical optical fiber, single fiber is transmitted from the branch room to the client end, the construction cost of the circuit divider and fiber core resources in ODN network is greatly reduced.
