■

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

■

XENPAK module

■

■

Line rate: 11.09 Gbps

■

Line rate deviation: ±20 ppm (G.709 LAN PHY with stuffing)

■

Dispersion window: –600 to +1200 ps/nm or –700 to +1500 ps/nm (maximum)

■

FEC type: Generic Reed-Solomon RS (255, 239) code computed as specified in Annex
A/G. 709
