The problem of stability of a system disturbed and high fault rate.The application improve after intelligent building optical network system to Construction Party, property,
Engineering commercial city is beneficial to, for project investment side：Can easily be constructed with investment reduction cost, simple system, project process and
The easy management and control of quality；For property user：System is stable, fault rate is low, easy to maintenance, autgmentability is strong, the later stage is intelligent
Function upgrading and extension are convenient etc.；For engineering business：Simple system easy care, maintenance cost is reduced, be easy for installation, construction
Low grade of cost of labor etc..
XPON network protection modes：4 kinds of protected modes, i.e. optical fiber backup, center light are mainly had according to xPON network structures
Device port backup, front and back end full backup and mixing backup mode.Consider cost, enforcement difficulty and intellectualizing system feature,
Most commonly optical fiber backup mode, that is, transmitting only needs single optical fibre, and also just two cores, cost pass one core of backup compared to traditional fiber
Defeated backup also economy.
The present invention is improved to the optical network device device of user terminal, to meet intelligent building optical network system multi signal
