LAD-2P LGX Module
Cyan also provides an external LAD-2P LGX terminal multiplexer module. The LAD-2P LGX is designed
to be used in OEO networks. The module is housed in an industry standard LGX form factor. The passive
LAD-2P LGX module provides two (East and West) DWDM channels of add/drop capacity and a 1310nm
add/drop port.
Channel spacing is at 100 GHz. The LAD-2P LGX module provides two DWDM channels:
•
Channel 30 – 1553.33nm, 193.0 THz
•
Channel 31 – 1552.52nm, 193.1 THz

1310nm Add/Drop Port
The LAD-8i module and the LAD-2P modules (in-chassis LAD-2P line card and the external LAD-2P
LGX) provide a standard 1310nm add/drop port, typically used for local client-side interfaces. The
client-side equipment may include various types of SONET/SDH, Ethernet, or OTN interfaces operating at
the 1310nm wavelength.
The LAD-8i and LAD-2P 1310nm add/drop ports are located on the module faceplate.
LAD-2G LGX Module
The LAD-2G LGX is an external terminal multiplexer designed to be used in OEO networks. The module is
housed in an industry standard LGX form factor. The passive LAD-2G LGX module provides two (East and
West) DWDM channels of add/drop capacity and a 1550nm add/drop port.
LAD-2G LGX channel spacing is at 100 GHz. The module provides two long-reach DWDM channels:
•
Channel 60 – 1529.55nm, 196.0 THz
•
Channel 61 – 1528.77nm, 196.1 THz
The LAD-2G LGX module provides a long-reach 1550nm add/drop port that is typically used for client-side
interfaces. The client-side equipment may include various types of SONET/SDH, Ethernet, or OTN
interfaces operating at the 1550nm wavelength.
