Model numbers
■
10-Gigabit digital wrapper with over-clocked G.709 framing
■
Generic Reed-Solomon forward error correction (GFEC) to transport 10GBASE-R (10-Gigabit
Ethernet LAN)
■
Reduced cost of deploying and maintaining the network due to:
■
Fewer optical-electrical-optical (OEO) conversions
■
Fewer optical amplifiers and regenerators
■
Two tunable wavelengths (channels) supported per XENPAK-OTN module
■
Link fault switchover
■
PC-1XGE-XENPAK-PIC feature support
