TruePulse is actively seeking Nortel Optera 3500 OC-48 boards NTN442AK and NTN442AL.   They may also be known as the Ciena OM3500 NTN442AK and the Ciena OM3500 NTN442AL.

The NTN442 series are OC-48 DWDM interface cards for the OM3500 that are each specific to a certain wavelength. TruePulse is actively searching for:

  • NTN442AK, HECI code SOCPAA3, is an OM3500 OC-48/STM-16 LR DWDM circuit pack, B1 Ch2, 1533.47nm
  • NTN442AL, HECI code SOCPAA4, is an OM3500 OC-48/STM-16 LR DWDM circuit pack, B1 Ch3, 1530.33nm

On the physical layer (layer 1), an Optera Metro 3500 network can be configured as a unidirectional path-switched ring/subnetwork connection protection (UPSR/SNCP), a 1+1 linear/MSP configuration, a 2-fiber bidirectional line-switched ring/multiplex section-shared protection ring (BLSR/MS-SPRing), or as an unprotected fiber optic run.

On the data link layer (layer 2), an Optera Metro 3500 network can be configured as an Optical Packet Edge ring with layer 2 protection, in accordance with Resilient Packet Rings (RPR) defined by the IEEE 802.17 working group.

TruePulse is looking for other Nortel OM3500 cards too.  But we are searching for equipment from a broad range of other telecom equipment and telecom test and measurement manufacturers, such as Fujikura, Dragonwave, IBM, Newmar and Wavesmith. Please tell us about any Central Office Telecom equipment that you have available for sale.
