1550 Cov Hloov Kho Kom Zoo Ib Yam

Khoom Zaub

1550 optical transmitter-1550nm sab nraud kho qhov muag hloov kho qhov muag uas yog qib siab tshaj plaws
khoom. Txais Kab Nqaim Kab dav dav （Hom.=0.3MHz imported thiab Qis suab nrov ntshuam DFB
laser ua lub hauv paus;

Txais yuav siab linear LiNbO3 sab nraud hloov kho raws li RF teeb liab
modulator, nrog tshwj xeeb CTB, CSO, dual lub siab ua haujlwm SBS Harpres tswj thiab lwm yam.
cov txuj ci thev naus laus zis; tsim rau cov tes hauj lwm xa mus ntev.

Nta

• Kev ua haujlwm siab: Tshaj tawm sab nrauv thev naus laus zis, tsis muaj laser chirp, tsis tshua muaj kev faib tawm tsis sib xws, siab qhov tsis sib luag, nrog tus yam ntxwv zoo nyob hauv 40 ~ 862 MHz.

• Nqaim bandwidth (0.65MHz), suab nrov qis dua, DFB nruam-nthwv dej laser, yog qhov txaus los txo cov cawv ntawm kev tawg.

• Kev khiav hauj lwm bandwidth mus txog 47 ~ 862 MHz (47 ~ 1080MHz).

• CNR ≥ 53dB thiab zoo rau CTB, CSO ntsuas.

• SBS: 13 ~ 18dBm kho tau.

• ITU txheem wavelength, ± 200GHz (± 1.6nm) kho tau.

• AGC / MGC hom kev xaiv ntawm qhov chaw. OMI tuaj yeem kho qhov zoo ntawm qhov chaw.

• Zoo meej RS232 kev sib txuas lus.

• Advanced SNMP network tswj kev ua haujlwm.

• 1+1 fais fab rov qab thaub qab, hloov tau.

• Casing qhov kub thiab txias pib tswj.

• Zoo heev P / P piv.

Cov lus tsis sib haum

1. CATV taub hau-kawg.

2. FTTH, FTTx PON, RFOG thiab lwm yam.

3. IPQAM thiab lwm yam.

4. Txhim kho qhov yooj thiab hloov kho ntawm lub network wavelength.

5. Ua tag nrho kev siv cov khoom siv kho qhov muag tam sim no kom ua tiav kev txhim kho network
peev xwm nthuav dav.

6. DWDM system ， CATV super-muaj peev xwm nraub qaum thiab Metropolitan cheeb tsam thaj chaw.
