WDM-EPORN
WDM EPORN : WDM, EPON is new technology that use in metro network of ring system.
1.Optic fiber is just one core that possible bellows.
⇒ Interactive communications
⇒ Maximum speed is 100Mbps
⇒ Equipment price, optic fiber price, management and maintenance price are lower.
⇒ High protocol is having no concern : Analog possibles application.
2.The data cycle line is ring system, data transmission line is star system
⇒ When happen cable difficulties or system difficulties, it can transmit to bypass automatically
⇒ It possibles to fast physical alternation under 50msec
⇒ It alternates with existing ethernet equipments and is consisted simple network
⇒ It can solve the existing Metro-network and subscribers network speed problems.
construct to plan solution
:
Metro ethernet +Lan
⇒ Metro ethernet + WDM EPORN + LAN
Metro ethernet + VDSL
⇒ Metro ethernet +WDM EPORN+ VDSL
3. Bandwidth assign each CT that applicate just as 100% to node tip
: Phase of bandwidth narrowing minimize in the process of lowest tip.
: It solves problem of tree-construction
CWDM, DWDM admission
: Reduction of optic fiber, economy of electric power, reduction of construction, maintenance and conservation expenses
5. All place of optic transmission network manege and control by mangerment of the highest tip equipment(L3 class s/w).
: It through bottom of CT-L3 and It reach each L2 switch or MC node. so, It can operate simple managemet-network by controlling highest tip.
6 Upward bandwidth control so easy.
7.Expenses of installation, maintenance and conservation are cheap.
