HDS-26S

GT LASERS HDS-26S (original model: HDBS-3000TX) series satellite L-Band optical transmitter, adopts high linearity DFB laser and direct modulated way. It can transmit 950~2600MHz L-Band analog or digital satellite signal (SAT-IF) receiving by satellite aerial radio high frequency head, to realize total transparency, high quality, long distance transmission through optical fiber. It also can sue satellite L-Band up/down link.

Optical operating wavelength of HDS-26S 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.
