JFOPT continues to invest in optical transceiver production, covering a full range of optical transceiver such as 1*9, SFP, 10G, 25G, 100G, 200G, 400G, 800G GPON/EPON/XG/XGSPON OLT transceiver. At the same time, our company provides TOSA, ROSA, BOSA semi-finished device solutions for the downstream peer. JFOPT's production line has a daily production capacity of 10,000 optical transceivers and 20,000 optical devices. In addition, JFOPT's optical transceiver have industry-leading high temperature resistance and anti-interference capability, and are widely used in computing centers, operators, traffic security, power facilities and other industries.
The JFOPT SFP28 25G 1310nm 300m ESR LC DX transceiver is a high-performance module designed for 25Gbps optical data transmission and reception over single-mode fiber. Equipped with a 1310nm DFB laser, it supports transmission distances of up to 300 meters.This transceiver complies with industry standards, including SFF-8472, SFF-8402, SFF-8432, and relevant sections of SFF-8431. It also features digital diagnostic functions accessible via a 2-wire serial interface, as outlined in the SFF-8472 specification.
