PON+CATV Double-fiber Transmission Solution

CATV1550 The whole network transmission technology has been relatively mature, and GEPON or XGPON technology transmission architecture is almost consistent, combined for the construction of urban all-optical network transmission scheme is suitable for the development of wired broadband, GEPON or XGPON through 1 fiber two-way interactive transmission, wavelength of 1490 / 1310 or 1577 / 1270nm, CATV uses 1550nm all-optical network 1 fiber transmission, so as to build double fiber transmission, with relatively low cost wired broadband network, to meet the present and future multiple business needs.

In the dual fiber transmission scheme, the 1550nm optical signal is output to the dual fiber optical transmission network through the high-power EYDFA device, and the dual fiber optical transmission network via OLT host. The dual fiber optical transmission network goes its own way. The CATV optical signal is independent on the 1550nm broadcast channel, while the PON1310nm / 1490nm or 1270nm / 1577nm optical signal is interactively transmitted on another core optical fiber, which is transmitted to the client optical fiber network through the dual fiber of various ODN equipment, and finally reaches the user's home after splitting through the user's optical network. 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 HSOS21176GNW equipment, 1GE + 4FE network port, 22 WIFI unless routing, While watching CATV video programs; Individual Internet needs can choose HSO1004G, 1GE + 3FE network port, Choose HSO1004GW for wireless router, 1GE + 3FE network port + 2*2 WIFI; Adopt the HSGS10076 optical receiver for the pure CATV service, Watch the CATV video business.

Features of the dual-fiber transmission solution:

1.Networking architecture consistent network maintenance is convenient: since PON transmission and CATV transmission are based on the same architecture, optical network is easy to operate from design, installation and operation, and maintenance is relatively convenient.

2. Network management system, operator managers can realize remote business network equipment management through our HFC network management system, open or close the functions of each equipment and fault location and other operations.
