The optical module or transceiver temperature is a very critical parameter that can affect the performance of the entire control system. A single malfunctioning module can lead to a catastrophic halting of important services and increased downtimes. As we all know, downtimes are just like bad dreams. Today, we are going to provide our readers with some useful information about the effect of alleviated module temperatures.

Tunable DWDM transceivers enable users to adjust the wavelength of the transceiver according to their network demand. These transceivers help in overall cost reduction by limiting the number of transceivers. Moreover, tunable transceiver offers great flexibility as they can be can adapt to the demands of a growing network. These days 25G SFP28, 10G XFP, SFP+ tunable DWDM transceivers are readily available on the market. In this post, we are going to provide you with comprehensive information on the differences between standard and tunable DWDM modules.

Based on refractive index distribution, multimode fiber (MMF) can be classified into two categories; graded-index fiber and step-index fiber. Graded-index and step-index fiber have different operating principles and they are considered for different networking scenarios. Ahead in this post, we are going to discuss the differences between the two types of multimode fibers and their applications also.

Multimode fiber normally refers to 62.5/125μm fiber and 50/125μm fiber. These numbers 50μm and 60μm represent the diameters of the core (plastic or glass) inside the optical cable. The fiber core of the cable carries the light which is used for data transmission. Whereas 125μm indicates that the diameter of the cladding, which surrounds the core to protect it and to prevent the leakage of the light. The maximum achievable bandwidth is a function of the cable`s core size.

As a basic component in optical communication networks, optical transceivers operate as media between different types of devices to receive and transmit data. Today, we have plenty of online and offline information available on transceiver modules from the perspective of their construction and packaging. However, we believe many people still have limited information about the most common, internal elements. In this article, we are going to provide you with some basic yet useful and interesting information about various components that are usually found inside optical transceivers.
