Now more and more 10GE level transmission requirement, the traditional way, also the only way is to use EAS2 board to access 10GE traffic from Router, and Cross-Connect to STM-64 line board to transit out, the problem for this solution is, too high cost the EAS2 board is.
Now another way is, upgrade your OSN3500 to hybrid version, add another package domain to access and transit data service, picture as below:
How it works
MSTP | Hybrid MSTP | |
Fiber occupation | 1 pair | 2 pair (1 for SDH, 1 for Package) |
Cross-Connect Board | SXCSA | PSXCSA |
Line Board | SLD64(2xSTM-64 Optical Interface Board) | SLD64(2xSTM-64 Optical Interface Board) PEX2(2-port 10G Ethernet Switching Processing Board) |
Data Service Board |
10GE Service, EAS2(2-port 10 Gigabit Ethernet Switching Processing Board) GE service, EGS4(4-port Gigabit Ethernet Switching Processing Board) FE service, EFS0(8 FE 10/100M Fast Ethernet Processing Board with LAN Switch) |
10GE service, PEX2(2-port 10G Ethernet Switching Processing Board) GE Service, PEG8(8-Channel Gigabit Ethernet Switching Processing Board) FE Service, PEFF8(8-Channel Fast Ethernet Optical Interface Board) |
traffic encapsulation | All in SDH domain | TDM in SDH domain, Data in Package domain |
Cost | EAS2 > PEX2+PEG8+PEFF8 |
