X-Krama's DWDM ( Dense Wavelength Division Multiplexing ) SFP is an optical transceiver module that can

combine a set of optical wavelengths of light into a single-core fiber for transmission. The channel spacing of the

DWDM SFP are small,such as 0.4 nm, 0.8 nm, 1.6 nm, etc., and requiring additional wavelength control devices.         

         A key advantage of the DWDM SFP is that its protocol and transmission speed are irrelevant. The DWDM-

based network can transmit data using IP protocol, ATM, SONET/SDH, and Ethernet protocols, and the processed

data traffic is between 100Mb/s and 400Gb/s. In this way, a DWDM-based network can transmit different types of

data traffic at different speeds on a single laser channel. From a QoS (Quality Service) perspective, DWDM-based

networks respond quickly to customer bandwidth requirements and protocol changes in a cost-effective manner.         

        Our DWDM SFPs are available for all 100 GHz or 50Ghz C-band wavelengths on the DWDM ITU grid. They are

designed to MSA standards to ensure a wide range of network device compatibility.  These DWDM SFP modules are

hot swappable and digital diagnostics functional areas via the I2C serial bus specified in the SFP MSA SFF-8472.

These modules are compliant with the IEEE802.3 Gigabit Ethernet standard and the ANSI Fibre Channel specification

and are suitable for interconnection in Gigabit Ethernet and Fibre Channel environments.
