OR303 -18dB to +2dBm Two-Way CATV Optical Receiver Optical Terminal (OR303A2 220V) for Digital TV
Upgrade:
The product adopts the shell of ice flower sandblasting process, and the waterproof level is increased to IP67! The OR303 module is suitable for digital TV, with a minimum received optical power of -18dbm. Average output level is 100dbuv!
Application:
OR303 optical receiver is used in trunk and branch fiber optic networks to provide high-quality video and data services. The product has complete functions, excellent indicators and high reliability. The preamp of the receiver adopts a detachable full GaAs amplification module. The post-stage is a gallium arsenide power multiplication amplifier module (or a more targeted combination of high-quality modules according to the actual needs of users). The optimized line design makes it an ideal model to build a CATV network.
It adopts steel cable hoisting die-casting IP67 waterproof shell which has good sealing, good heat dissipation, and has a complete shielding effect on electromagnetic wave interference. The optical receiver can be used for EPON networks.
Features:
- High-quality waterproof cast aluminum shell and its waterproof level reaches IP67 standard
- The device can be hung by strand or wall-mounted
- Beautiful and generous double-shielded panel ensures good EMC indicators
- GaAs low-noise amplifier circuit for preamp increases the receiving sensitivity of the device
- AGC control range -15 to 0dBm (OR303), output basically unchanged
- Accurate optical power detection circuit, accurate real-time display of 13 statuses through LED indicator lights
- With output port plug-in, you can switch branches or assign outputs at will
- Built-in button fuse box for easy and quick replacement
- T type + E type anti-surge and anti-lightning circuit is adopted to effectively prevent power supply damage
Package Included:
- 1 x OR303 Optical Receiver
Packaging Details:
- G.W.: 1.7kg
