Optical Transceiver Mechanical Dimension
Optical Transceiver Product Details
The optical transceiver 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.
Yingda pack all SFP transceivers in blister boxes, 10pcs / box, it features a specially designed, precise-size card slot, ensuring stability and reliability.
