Product Description
HDS-26D series optical transmitter, adopt high linearity DFB laser, modulated directly. It can transmit 30~2600MHz digital TV, move media broadcast ( MMB, CMMB ) and satellite live telecast TV ( DBS , SAT-IF ) signal.
Optical operating wavelength of HDS-26D is optional as 1310nm or 1550nm.
1550nm optical transmitter, ITU standard wavelength can be selected, suitable for DWDM to realize network-upgrading and capability-expansion. It can work together with EDFA, YEDFA to amplify the optical power. It can be compatible with any FTTx PON technology.
1. High wide band: 30~2600MHz.
2. Suitable for Digital TV & Satellite TV application.
3. One fiber can transmit signal of 10 sets of TV, DTV and satellite TV.
4. HGHL DFB laser, can choose cooling and non-cooling.
5. 1310nmTX, output power upto 30mW.
6. 1550nmTX, ITU wavelength optional, apply in DWDM, reach network promotion and dilatation.
7. 1550nmTX can be amplified by EDFA, YEDFA to cover large-scaled FTTH , compatible with any FTTX PON technology.
8. Multiple performance frame, suitable for application of different scale network
9. Excellent P/P ratio.
1. FTTH for Digital TV & Satellite TV
2. FTTx PON, (EPON, GPON)
3. Move TV media broadcast ( MMB, CMMB )
4. Other digital video application
