SFP Module Full Form Product Details

The SFP Module Full Form 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. It can be used together with SC patch cords for termination connection.

Single-fiber bidirectional optical transceiver modules must be used in pairs. The SC 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.

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.

All 1.25Gbps SFP module full form offered 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 sfp transceivers can be used in wide range of fiber optic link: router, switch, server, network card, firewalls, media converter, etc.
