8-port, high-speed OC-3/12/48 VLF Main (LNW82)

Optical specification

The LNW82 OC3/OC12/OC48 OLIU circuit pack is an 8-port, PTM-based, multi-rate (OC-3, OC-12, OC-48), high-speed optical circuit pack.

The LNW82 circuit pack and some of the supported OC-N PTMs are approved for OSP deployments. You must install PTMs that are approved for industrial temperatures to use the LNW82 in OSP environments. All of the DWDM PTMs are approved for commercial temperatures and are therefore only approved for Central Office environments.

The LNW82 OLIU circuit pack supports a maximum of 8 OC-3 ports, 8 OC-12 ports, or 2 OC-48 ports. Mixing port optical rates is supported with the following restrictions:

OC-48 interfaces are only supported on ports 1 and 5.
When port 1 or 5 is used for an OC-48 interface, then the next three adjacent ports are unavailable for use. For example, if an OC-48 pluggable transmission module is installed in port 1, then ports 2, 3, and 4 are unavailable for use.

For detailed system, transmitter, receiver, and link budget specifications, see

Allowed optics for LNW82 packs

The table below lists the OC-3. OC-12, and OC-48 Pluggable Transmission Modules (PTMs), also known as small form-factor plug-ins (SFPs), that may be used in the LNW82 circuit pack.

Alcatel-Lucent 1665 DMX utilizes Pluggable Transmission Module (PTM) optics on the LNW82 circuit pack. To ensure proper optical performance, mechanical fit, compliance with EMC, and compliance with laser safety standards, the Alcatel-Lucent specified PTM transceivers listed in the table below must be used.

Only the Alcatel-Lucent specified PTM transceivers listed below are compatible with Alcatel-Lucent 1665 DMX software. If non-Alcatel-Lucent specified PTM transceivers are installed in Alcatel-Lucent 1665 DMX, the system will reject that transceiver, and that optical port will become inoperable (until approved parts are installed).
