Optiva OTS-2 Series Satcom Band Fiber Optic Links
Satcom Band Highlights
The OTS-2 Series Satcom Band Fiber Optic Links are a family of SNMP man- n Satellite bands: C, X, DBS, Ku, Ka
aged fiber optic transmitters and receivers that provide high-performance
downlink and uplink transport within the modular Optiva platform. C, X, n Low RIN source laser
DBS, Ku- and Ka-Band modules are available. Optiva satcom band modules n Microprocessor-based transmitter
utilize EMCORE’s high-performance ultra-low Relative Intensity Noise (RIN) control for laser bias, modulator
source laser technology with high optical input power capable photodi- bias and link gain
odes, and feature microprocessor-based transmitter and receiver control for n DWDM cooled DFB laser, 10 dBm
laser and modulator bias. Satcom band modules come with variable RF gain output
to provide consistent microwave link operations.
