8 channel DWDM Mux/Demux OMD5/8 (LNW785)

Optical specification

The LNW785 series supports supporting ITU-T DWDM channels 52 through 59 (195.20–195.90 THz). These channels, which have wavelengths between 1530.3 and 1535.8 nm, are at the short-wavelength end of the C-band. This region is chosen because it has the lowest chromatic dispersion in standard single-mode fiber (SSMF) and because it contains Alcatel-Lucent 1665 DMX's most popular DWDM channel, 59.

The LNW785 must be installed in a shelf with an LNW2 and at least one Main pack (VLF or non-VLF).

Cross-connections

The following 1-way optical cross-connections are supported on the OCH interfaces of the LNW785.

• OCH to/from OCH pass-through cross-connections

• OCH to/from OTU2 add/drop cross-connections

• OCH to/from OC-192 Line add/drop cross-connections

• OCH to/from alien (remote shelf) add/drop cross-connections
