DWDM SFP Dense Wavelength Division Multiplexing (DWDM: Dense Wavelength Division Multiplexing) is the ability to combine a set of optical wavelengths to be transmitted in a single fiber.DWDM SFP belongs to the wavelength division multiplexing technology, which can couple different wavelengths of light into a single fiber to be transmitted together.

DWDM SFPs are available in 0.4nm, 0.8nm, and 1.6nm channel spacing, depending on the need, with smaller spacing and the need for additional wavelength control devices. one of the key benefits of DWDM SFPs is that the protocol and the transmission speed are not correlated. DWDM-based networks can transmit data using IP, ATM, SONET/SDH, and Ethernet protocols, and can handle data traffic between 100 Mb/s and 400 Gb/s. This allows DWDM-based networks to be used in a variety of applications, including IP, ATM, SONET/SDH, and Ethernet. In this way, DWDM-based networks can transmit different types of data traffic at different speeds over a laser channel. From a QoS (Quality of Service) point of view, DWDM-based networks respond quickly and cost-effectively to customer bandwidth demands and protocol changes.

DWDM SFP series optical modules include DWDM SFP 40KM, DWDM SFP 80KM, DWDM SFP 120KM, DWDM SFP 160KM and other series products. We provide commercial grade temperature, extended grade temperature and industrial grade temperature for customers to choose and use. The product rate ranges from 155Mb/s~3.072Gb/s, which can meet the ultra-long data transmission distance from 40km~160km. They are mainly used in Fast Ethernet, Gigabit Ethernet, switch interface, router/server interface and other fiber optic links. The optical modules can be adapted to Huawei, Huasan, Cisco, Alcatel-Lucent, Juniper, Ericsson, HP and other equipment.
