Whether is worth to Use EDFA Amplifier in Long WDM System?

 Introduction to EDFA Amplifier   EDFA amplifier, also referred to as erbium-doped fiber amplifier, is basically composed of a length of Erbium-doped fiber (EDF), a pump laser, and a WDM combiner. When it works, the pump laser with 980 nm or 1480 nm and the input signal around 1550 nm [ Continue reading…]

Three different types of QSFP28 Optical Transceiver

  The appearance of the QSFP28 optical transceiver is the same as that of the 40G QSFP + optical transceiver. The difference is that QSFP28 optical transceiver can transmit optical signals up to 100G. Therefore, QSFP28 optical transceiver has become the mainstream 100G optical transceiver and the preferred solution for [ Continue reading…]

Do you know The difference between CWDM transceiver and DWDM transceiver?

DWDM technology multiplexes the tight spectral spacing of a single optical fiber carrier in a given fiber to take advantage of the transmission performance that can be achieved. DWDM wavelength spacing is very tight, because the closer the spacing is, the more channels per fiber will be reused, and thus [ Continue reading…]

What areas does CWDM SFP apply to?

SFP stands for “small form-factor pluggable.” SFP transceivers are compact and hot-pluggable devices that act as an interface between networking equipment (switch, router, network card) and interconnecting cabling (copper or fiber).   The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing [ Continue reading…]

The difference between optical module and optical transceiver

Optical fiber has become people’s first priority in communication installation due to its advantages of fast transmission speed, long distance, safety and stability, and strong anti-interference ability. At present, the long-distance data transmission used in many smart projects basically uses optical fiber transmission. The connection between these requires an optical [ Continue reading…]

What Is the Difference between 100G Active Optic Cable and 100G Direct Attach Cable?

We know that both 100G active optic cables (AOC) and 100G direct attach cables (DAC) are used to transmit data. However, there are some differences between 100G active optic cables and 100G direct attach cables. Next, we will introduce the difference between these two types of cables in detail.   [ Continue reading…]
