DWDM SFP

The DWDM (Dense Wave Multiplex) SFP optical module is a dual-fiber, two-way 10-megabit light module that provides high-capacity bandwidth in a network with 32 fixed wavelengths to support the International Telecommunication Union (ITU) 100 GHz wavelength. DWDM SFP optical module channel interval as needed to have 0.4nm, 0.8nm, 1.6nm and other different intervals, its interval is small, so the need for additional wavelength controller parts, DWDM SFP optical module has a very key advantage, its protocol and transmission speed is not related. DWDM, on the other hand, typically uses denser channel intervals and is used for large optical networks over longer distances. If you are looking for a long-distance SFP module and want better scalability, the DWDM SFP optical module is ideal.

DWDM Introduction

DWDM technology is to utilize the bandwidth of single-mode fiber and the low-loss characteristics, using multiple wavelengths as carriers, allowing each carrier channel to be transmitted simultaneously within the fiber. Compared with the universal single-channel system, the dense WDM (DWDM) not only greatly improves the communication capacity of the network system, makes full use of the bandwidth of optical fiber, but also has many advantages such as simple expansion and reliable performance, especially it can directly access a variety of services and make its application prospect very bright. DWDM is structurally divided and currently has an integrated system and an open system. Integrated system: the optical signal requiring access to the single-optical transmission device terminal is to meet ITU standard light source.

DWDM Transceivers

The DWDM optical module reuses multiple optical signals with different wavelengths into a single fiber, which eliminates the need to consume any power. Designed for high-capacity, long-range transmission, these optical modules can reach speeds of up to 10Gbps and operating distances of up to 120km. At the same time, the DWDM optical module is designed according to the Multilateral Protocol (MSA) standard to ensure a wide range of network equipment. The DWDM optical modules on the market are usually: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2, and DWDM XENPAK optical modules.The DWDM SFP optical module provides a high-speed serial link with a signal transmission rate of 100 Mbps to 2.5 Gbps. The DWDM SFP plus optical module is the best choice for 10 megabit maximum bandwidth applications.

DWDM SFP from Professional China Manufacturer

The basic function and principle of the DWDM optical module, like other optical modules, are to convert electrical signals to optical signals, and then to convert optical signals to electrical signals. However, the DWDM optical module is designed for DWDM applications and it is worth mentioning that it has its own features and functions. Compared with the Coarse Wave Multiplex (CWDM) optical module, the DWDM optical module is designed for single-mode optical fiber and operates between the DWDM wavelengths of 1528.38 to 1563.86nm (channel 17 to channel 61), as specified by ITU-T. The DWDM optical module has an SFP 20 pin connector for hot-swap capability, its transmitter part uses DWDM multi-quantum trap DFB laser, and according to the international safety standard IEC-60825, the laser is a Class 1 laser.

In addition, many suppliers’ DWDM optical modules meet SFF-8472 MSA standards. The DWDM SFP optical module can be used to amplify DWDM networks, fibre channels, fixed and reconfigurable OADM ring network topology, fast Ethernet, Gigabit Ethernet, and other optical transmission systems. The DWDM SFP-optical module is 10GBASE-ZR/ZW compliant and can be used for 10G fiber optic cables. DWDM XFP modules, DWDM X2 optical modules, and DWDM XENPAK light modules are commonly used in applications such as 10G Ethernet, 10G Fibre Channel, SONET and SDH. In addition, these DWDM optical modules can also be used for switch-to-switch interfaces, switchback board applications, router/server interfaces, and more.
