A comprehensive know-how regarding DWDM transceiver

The emergence of DWDM technology has essentially altered the landscape of fiber optic networks, with DWDM optical transceivers as one of its significant factors. We have implemented DWDM networks in various areas and industries to enhance network capability.

HOW CAN WE DEFINE THE DWDM TRANSCEIVER AND ITS FUNCTION?

DWDM optical transceiver works like other standard fiber optic transceivers to change electric signal to fiber optic signal and again to an electric signal. The dissimilarity is that DWDM optical transceiver leverages the technology of DWDM to multiplex several wavelengths or different fiber optic signals over a single fiber to secure important fiber belongings. We have designed it for SMF and works at a wavelength from 1528.38 nanometers to 1563.86 nanometers, as defined by ITU-T. Apart from applying long-range transmission, we can also use DWDM transceivers in a switch-to-switch connection, switched backplane implementations and server interface, etc. DWDM optical transceiver favors above 10 Gbps and can cover a range above 120 kilometers, making it most favorable for high-capability and long-haul communications.

COMMON TYPES OF DWDM TRANSCEIVER:

DWDM optical transceivers are attainable in several kinds, favoring communication rates from 155 megabits per second to 10 gigabits per second. We can categorize DWDM transceiver by form factors and data rates like DWDM SFP+ transceiver, DWDM SFP transceiver, DWDM XFP transceiver, etc., as follows.

DWDM SFP:

DWDM SFP optical transceivers give an excessive speed serial connection at signal rates from 100 megabits per second to 2.5 gigabytes per second. The SFP modules of DWDM meet the demands of the IEEE802.3GbE and requirements of ANSI of Fiber Optic Channel and are appropriate for connections in GbE and Fiber Channel conditions.

DWDM XENPAK:

A significant step in the development is DWDM XENPAK. It is the first-ever 10 Gigabit Ethernet optical transceiver in favor of DWDM. DWDM XENPAK optical transceiver favors 32 multiple channels for above 200 kilometers with the help of fiber optic amplifiers recognized as EDFAs.

DWDM X2:

DWDM X2 optical transceiver is a good performance, serial fiber optic transponder module for excessive speed, 10 Gigabit data transmission implementations. The fiber optic module is entirely adaptable to IEEE 802.3aeGbE, perfectly appropriate for 10 Gigabit Ethernet datacom implementations.

DWDM XFP:

Optical transceiver agrees with the existing XFP MSA requirements. It is cost-effective and small in size. It favors SONET/SDH, 10 Gigabit Ethernet, and 10G Fiber Channel implementations.

DWDM SFP+:

We have created DWDM SFP+ particularly for carriers and big enterprises that demand a cost-effective, scalable, flexible network system. It is also smaller in comparison to the previous XFP. Moreover, it is the best choice for 10 Gigabits' highest bandwidth implementation.

As for tunable or fixed wavelength, we can divide DWDM transceiver into tunable DWDM transceiver and fixed wavelength DWDM optical transceiver. Fixed wavelength DWDM optical transceiver can only transfer a particular number of wavelengths, typically at 1310 nanometers and 1550 nanometers for 10 Gigabit data transmission implementations. However, the tunable DWDM optical transceiver facilitates flexible operating wavelength or channel. Usually, these tunable DWDM fiber optics are for C-B and 50 gigahertz. We can set around 88 multiple channels with intervals of 0.4 nanometers. We use tunable optical transceivers typically as “spare-optics” in any emergency case.

So why do we need tunable DWDM transceivers? We have adopted hundreds of wavelengths in DWDM 50 gigahertz with technology development. We require many backup DWDM fiber optic modules for extra protection, and tunable DWDM optical transceiver modules are the options. Moreover, it is typical to reserve fixed wavelength DWDM optical transceivers in an emergency, like network downtime. However, we cannot say which particular channel we need. Tunable DWDM optical transceivers facilitate fixed wavelength projects built on our requirement while saving visual fiber resources.

THE PRESENT STATUS AND IMPLEMENTATIONS OF DWDM TUBALE TRANSCEIVERS:

The rapid development of network traffic has caused the evolution and development of the data center. So brings significant chances for the fiber optic transceiver industry. As the core factor in long-haul and excellent fiber-optic networks, DWDM transceivers are progressing with fresh ideas, modern technologies like simplified packaging, excessive speed, smaller size, and low power consumption. We broadly apply DWDM optical transceivers in cable companies and telecoms, an essential part of their core systems. Or any company is running a heavily populated data center, specifically hyper-scale cloud service suppliers for their architectures or colocation suppliers for their multi-rented spaces.

• The 5 Gigabit front-haul network supports the requirement for DWDM fiber optic modules. The rush of data traffic and enhanced implementation of 5 Gigabit, the Internet of Things will fuel the performance of excessive speed WDM fiber optic modules, and the requirement for DWDM optical modules in long-haul communication is vast.
• The growth of the data market also exerts the requirement of DWDM transceiver modules. The program utilizing cloud technology like online games, video, Al further technics will continue to exercise the need for DCI. Moreover, the movement between massive data centers demands DWDM optical transceivers to optimize efficiency and control the great computing demands of enterprises.

CONCLUSION:

It does not matter how quickly Internet technology develops and how advanced it can be in the future. Fiber optic transceivers will be an essential part of fiber optic communication systems. Where there we have demands, there exists a market. We have extensively adopted DWDM transceivers in the past, and we will continue to upgrade and develop them in the coming years. Although we don't have enough market share for DWDM tunable optical transceivers, we can still see excellent implementation potential. The question to tune or not relies upon you.
