| 2 | Tāone-Rohe B | 40 | 14 | 10GE |
| 3 | Tāone-Rohe C | 40 | 8 | 10GE |
| Tapeke | --- | 32 | 10GE | |
2.1.Ngā whakaritenga mō te hongere tuku:
2.1.1. Te tuku i ngā ratonga 14*10 Gigabit mai i te rūma rorohiko o te tāone ki te rūma rorohiko o Nanhai
2.1.2, te mahi ara matua, te pana ara tārua≤32mms
2.1.3. Ka taea te whakamahi i te OTU ā-rohe hei hanga i te tohu, hei whakanui, hei tango hoki i te karaka.
2.2. Ngā whakaritenga mō te hongere tuku:
2.2.1. Te tuku i ngā ratonga 14*10 Gigabit mai i te rūma rorohiko o te tāone ki te rūma rorohiko o Shunde
2.2.2, te mahi ara matua, te pana ara tārua ≤ 32mms
2.3.3. Ka taea te whakamahi i te OTU ā-rohe hei hanga i te tohu, hei whakanui, hei tango hoki i te karaka.
2.3. Ngā whakaritenga mō te hongere tuku:
2.3.1. Ka tukuna ngā ratonga 8*10 Gigabit mai i te rūma rorohiko o te tāone ki te rūma rorohiko o Gaoming.
2.3.2. Kei te mahi te huarahi matua, ā, ko te pana huarahi kē he ≤32mms
2.3.3. Ka taea te whakamahi i te OTU ā-rohe hei hanga i te tohu, hei whakanui, hei tango hoki i te karaka.
3.1. Whakaahuatanga o te kaupapa
3.1.1. I te whakaaro ki te whakawhānui i te kaha, kua hangaia te waeine whakakorenga ngaru kia rite ki ngā ngaru e 8
3.1.2. Te tatau i ngā raraunga i homai mō te whakaiti i te taura whatu (kei roto ko te ngaronga hononga me te ngaronga whakaurunga).
3.1.3. Tātaitanga mana whatu hononga:
Kotahi te ahunga: Ka tatauhia te mana kanapa ngaru-kotahi o te kōwae whatu i te 0dBm (-2～3dBm), ka whakanuia e BA ka whakaitihia e OLP, ko te mana muka whatu e haere mai ana ko +4dBm, ka whakaitihia e te raina 27dBm, ka whakaitihia te OLP 2dB, ā, ko te mana e tomo ana ki te PA ko -25dBm. I muri i te whakanui PA 20dB, ko te mana ngaru-kotahi ko -5dBm, i muri i te tango-ngaru DEMUX, ko te mana ngaru-kotahi ko -10dBm, e kīia ana kei roto i te awhe aro o te kōwae whatu;
Whakamuri: Whai muri i te tatau, ko te mana ngaru kotahi i te pito whiwhi he -10dBm, e kīia ana kei roto i te awhe aro o te kōwae whatu.
3.1.4. Tātaitanga OSNR pūnaha (māmā): OSNR=58+4-27-1-6=28dB≥24dB, e tutuki ana i ngā whakaritenga hoahoa.
3.2. Ngā painga o te otinga
3.2.1. Whakamahia te DWDM hei whakarea i ngā ratonga 40 ki runga i te taura whatu kotahi mō te tuku, e tino penapena ana i ngā rauemi taura whatu me te whakarite i te whānui o te hononga;
3.2.2. Te pumau teitei: Ka whakamahia e tēnei hoahoa otinga te tiaki ara takirua OLP 1+1, ka tautoko i te whakawhiti aunoa, ā, ka whakarite i te pumau o te pakihi;
3.2.3. Ka whakamahia e ngā taputapu WDM te hoahoa modular, ka wehea te kaha me te kore kaha, ka ngāwari ki te whakawhānui, me whakanui noa i te papa ratonga ina whakawhānui, me te kore e whakararu i te pakihi o nāianei.
3.2.4. Kei te whakamahi te papa OTU i te hoahoa 3R, ka taea te hanga anō i te tohu, te whakanui ake i te karaka me te whakarite anō i te wā kia kore ai te tohu e hē.
3.2.5. Tautoko i ngā ratonga rerekē hei uru atu ki te SDH, PDH, CATV, Ethernet, raraunga reo, me ētahi atu, e hototahi ana ki ngā taputapu mai i ngā kaihanga rerekē.
3.2.6. Ka whakaratohia e te taputapu he pūtake hiko tārua wera 1+1, e whakapai ake ana i te pumau o te taputapu.
3.2.7. He kaha ngā mahi whakahaere whatunga, ka taea te whakahaere whatunga mamao, te aroturuki pakihi ipurangi-tūturu, me te whakahaere i te tiaki.
