TruePulse is looking to purchase 29H-U OLIUs for the Lucent DDM-2000.  You may also be familiar with the board as the Alcatel 29H-U, or even the Nokia, 29H-U.

The 29H-U, HECI code SNRXD7TAAA / SNRXD7T, is an OLIU (optical line interface unit) 1550nm long reach OC-12 circuit pack for the Lucent DDM-2000.  OC-12 interface supports span lengths up to 94 km, assuming 0.25 dB/km single-mode fiber (including splices) and adhering to Lucent’s span engineering rules.  It uses a DFB laser, and scrambled NRZ optical line coding. 

The 29H-U has a "-U" in its designation to indicate it has a universal optical connector.

The 29H-U is similar in many ways to the 29G-U, SNRXD70, which is an OLIU 1310nm long reach OC-12 circuit pack.

Nokia provides only limited support for the DDM-2000 product line.

Not only are we searching for Lucent DDM-2000 boards, we are also searching for boards for many of the Alcatel/Lucent networking platforms, including the FT-2000, Galaxy Power, the DACS IV and the Lambda Unite.

Please let us know of any surplus Nokia/Alcatel/Lucent central office equipment that you have available.
