E-sports competition: Every millisecond of excitement and fairness is based on a reliable network.

DWDM Optical Add/Drop Multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple 100 GHz DWDM channels in the C-band into one or two fibers....

DWDM, that is, dense wavelength division multiplexing. "Dense" means that the wavelength channels are very narrow and very close to each other. The working principle of DWDM is to combine and simultaneously transmit multiple signals of different wave...

The 100G OTN Transmitter supports one QSFP28 client interface and one CFP line-side interface to support single-channel 100Gbps large-grain data transfers. The industry‘s most advanced coherent technology and FEC forward error correction cod...

HTF‘s 100G QSFP28 BIDI 20km & 100G QSFP28 BIDI 30km single-fiber optical transceiver module is an optical transceiver module designed for single-channel optical transmission of 20km and 30km or more....

The optical transmitter portion of the transceiver incorporates a 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) array, a 4-channel input buffer and laser driver, diagnostic monitors, control and bias blocks. For module control, the contr...

Coarse wavelength division multiplexer: A wavelength division multiplexer combines a series of optical signals carrying information but with different wavelengths into one bundle and transmits them along a single optical fiber; at the receiving end, a certai...

DWDM OTN solution design requirement

In the field of optical fiber communication, Dispersion Compensation Module (DCM) (also called Dispersion Compensation Unit, DCU) is used to compensate dispersion, for example, to compensate dispersion in a very long transmission fiber. Usually, ...

Both AOC active optical cable and DAC high-speed cable are used for short-distance server interconnection and server-switch interconnection in data centers, so what is the difference between them? Let’s take a look together....

What Is OTN Network—Optical Transport Network?

CWDM and DWDM

DWDM is a transmission technology in optical fiber communication. It uses one optical fiber to transmit multiple optical carrier signals of different wavelengths at the same time, and divides the wavelength range used by the optical fiber into several cha...

Dense Wavelength Division Multiplexing (DWDM) is the ability to multiplex optical signals of different wavelengths into the same optical fiber for transmission....
