Note 1: To obtain the definition of the OPTera Metro 3500 hardware baseline, contact the
+44-20-8945-2333 for International Optical Networks (ION).
Note 2: The 2x100BT-P2P circuit pack and OPE circuit pack distances are IEEE-specified segment
lengths, based on the assumptions that all distances are for full-duplex transmission. The IEEE
distances reflect worst-case attenuation scenarios.
Note 3: The PECs for the sixteen OC-48 LR DWDM circuit packs in C-Band are as follows: NTN442AA,
AB, AC, AD, BA, BB, BC, BD, CA, CB, CC, CD, DA, DB, DC, DD.
Note 4: The PECs for the seven OC-48 ER DWDM circuit packs in C-Band are as follows: NTN408AA,
AE, AJ, AN, CJ, CN, DA.
Note 5: The PECs for the eight OC-48 LR DWDM circuit packs in L-Band are as follows: NTN442JA,
JB, JC, JD, LA, LB, LC, LD.
Note 6: The PECs for the eight OC-192 DWDM
G.709 FEC
circuit packs in C-Band are as follows:
NTN445EA, EB, EC, ED, FA, FB, FC, FD.
Note 7: The PECs for the eight OMX + Fiber Manager 4CH are as follows: NT0H32AE, BE, CE, DE,
EE, FE, GE, HE.
Note 8: The PECs for the eight Enhanced OMX + Fiber Manager 4CH are as follows: NT0H32AF, BF,
CF, DF, EF, FF, GF, HF.
