OP+LBT
L-Band Satellite Optical Transmitter
The OP+LBT is a fiber optic transmitter that converts satellite L-Band signals into the optical domain for transmission over single-mode or multimode fiber. With 1310 nm and CWDM wavelength options, this module is suitable for a wide variety of applications.
The OP+LBT module accepts one electrical L-Band input (250 MHz to 2.25 GHz) and provides one fiber output, along with an electrical output for monitoring and distribution purposes. The OP+LBT occupies two slots in a 6800+™ frame, allowing for up to 10 independent L-Band signals in a single 2RU frame.
Features
- 75 ohms type F connector input
- Accepts L-band frequency range from 250 MHz to 2.25 GHz
- Wide dynamic range RF input from -60 to –20 dBm
- Transmits video, audio, and data modulation protocols transparently
- Additional amplified RF output for monitoring or distribution
- ~45 dB dynamic range AGC and manual output signal level settings
- Remote LNB powering and control with configurable 13 or 18 V with up to 450 mA current DC power supply
- Fully hot-swappable from front of frame
- Available in 1310 nm FP and DFB CWDM wavelength options
- Supports single- or multimode fiber
- SC/PC, FC/PC or ST/PC fiber optic connector
- Dual-slot form factor in 6800+ frames, including 2RU FR6802+QXFE or deskmount FR6800+MB
- Complete module status monitoring via card-edge LEDs
- CCS Navigator™ control and monitoring, including NUCLEUS™ control panel
