Optical Module Product Details
The optical module consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and control unit. All modules satisfy class I laser safety requirements. The gold-plated contacts on the surface of the gold fingers are thickened to enhance conductivity and allow for repeated insertion and removal.
Single-fiber bidirectional optical transceiver modules must be used in pairs. The LC small square connector can be used with single-mode fiber optic patch cords to achieve high-precision and accurate connection. It is plug-and-play, flexible and convenient.
All 1.25Gbps optical modules offer by Yingda use high-quality imported chips to ensure low power consumption and a stronger, more stable signal. High-quality lasers ensure high-speed signal transmission without packet loss.
The optical module outer shell is made of zinc alloy, machined by die casting on a lathe, and electroplated for oxidation resistance, making it drop-resistant, wear-resistant, heat-dissipating, and heat-proof. The reinforced design of the stable interface connections ensures sturdiness and durability. Furthermore, the DDM function can monitor five parameters in real time: module temperature, laser bias current, antenna number 6, transmit optical power, and receive optical power, thereby quickly locating the fault in the fiber optic link, simplifying maintenance, and improving system reliability.
