4.1.1 10G Lambda Transport, OEO Application Feature Set
• Used in Cyan Z33 and Z77 shelves.
• With LAD-4/A: 4-channel DWDM, 100 GHz spacing, front access — the XFP module determines
which wavelengths are accessed.
• With LAD-8/A/E/i/X: 8-channel DWDM, 100 GHz spacing, front access — the XFP module
determines which wavelengths are accessed.
• OEO configuration.
• LAD-4, LAD-8 or LAD-8i: Link budget 16 dB (reach ~64 km), LAD-4A or 8A: Link budget 24 dB
(reach ~96 km), LAD-8E: Link budget 32 dB (reach ~128 km), LAD-8X: Link budget 40 dB (reach
~160 km).
• Quad 10G transponder cards (2 TDM+2 Ethernet).
• 3R functionality (re-time, re-shape, and re-transmit).
