10GHz Directly Modulated Laser Module, 1550 or 1310nm, DML The directly-modulated laser (DML) is a cost-effective solution for 10Gbps digital transmission of up to 60 km using traditional intra-city SMF-28 single-mode fiber links. Or It is also suited for analog fiber. the present inventionrelates to the field of optical modules, and in particular, to a high-speed PAM4 optical transceiver module based on DML. But behind every stable link, there's a laser doing the real work. When we talk about EML vs DML, we're really talking about what makes those numbers possible in the first place. Understanding the difference between DML and EML is essential for selecting the right transceiver for your data center. GIGALIGHT 200G QSFP56 FR4 optical transceiver module is used for medium distance interconnection between devices within data centers and is compliant with IEEE 802. 3bs 200GBASE-FR4 Ethernet transport protocol and also compatible with InfiniBand HDR transport protocol.
