Why Rofea

Key Strengths at a Glance

What makes Beijing Rofea Optoelectronics a leading manufacturer of electro-optic modulators, photodetectors and RF-over-fibre platforms since 2009.

TFLN Modulators up to 110 GHz
Thin Film Lithium Niobate (TFLN) Mach-Zehnder intensity modulators in 20G, 25G, 40G, 70G and 110G formats — top-tier electro-optic performance for 5G backhaul, datacom and mmWave platforms.
Full EOM Portfolio
Lithium niobate modulators at 780, 850, 1064, 1310 and 1550 nm — intensity, phase, Y-waveguide variants and bias-point controllers.
Acousto-Optic Modulators
AOM series for fibre-laser systems, free-space and fibre-coupled acousto-optic designs — precision control for quantum optics and material processing.
Photodetectors
APD detectors, balanced receivers, single-photon detectors (InGaAs), silicon photodetectors up to 2.5 GHz — receiver solutions for optical and quantum communication.
RF over Fibre
Microwave-fibre transmission modules at 0.6–6 GHz and 3/6 GHz analogue links — low-loss RF signal distribution over optical fibre.
Quantum & Research
Y-waveguide modulators for Quantum Key Distribution (QKD), narrow-band filters, fibre-laser amplifiers (EDFA, SOA) and optical delay lines for research laboratories.
