Abstract
The invention discloses an integrated optical transceiver used for a CSFP module. A first laser device, a first photodiode, a first jumper-wire connector base, a first internal-core part and a first laser-device focusing lens are sequentially connected so that a first single-fiber bidirectional assembly is formed. A second laser device, a second photodiode, a second jumper-wire connector base, a second internal-core part and a second laser-device focusing lens are sequentially connected so that a second single-fiber bidirectional assembly is formed. The integrated optical transceiver used for the CSFP module integrates the two single-fiber bidirectional components onto one metal square shell through an ingenious structural design so that an SFP module is capable of accommodating the two single-fiber bidirectional components at the same time and data throughput is doubled. The internal-core parts which are comparatively large in size and provided with filters and the focusing lens are arranged at a middle position of the square shell which is comparatively large in space so that the optical transceiver is more compact in structure and more stable in product performance.
