A Comprehensive Introduction to Tunable DWDM Transceivers
Jul 21 , 2022
Tunable DWDM transceivers allow users to adjust their wavelengths according to actual network needs. This results in a reduction in the number of spare transceivers used to avoid DWDM network failures and provides flexibility to accommodate growing networks. Tunable modules on the market mainly include 10G SFP+, XFP and 25G SFP28 tunable DWDM transceivers. So, is there any difference between tunab...

What is the difference between CWDM technology and DWDM technology?
Sep 16 , 2022
In WDM technology, there are CWDM coarse wavelength division multiplexing technology and DWDM dense wavelength division multiplexing technology. Literally, these two technologies have different degrees of density in a band, but there are still many practical technologies and applications. difference. ①The wavelength interval is different The CWDM carrier channel spacing is wider and each band is 2...

Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8
Oct 14 , 2022
At present, the main products of 400G transceivers are QSFP-DD, OSFP and CFP8. This article introduces: Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8 1: QSFP-DD provides maximum port density. This makes QSFP-DD more attractive than OSFP form factor modules and larger CFP8 modules. 2: The power consumption (the maximum power that the module can dissipate without damaging the interna...

How to solve when the optical module fails?
Nov 11 , 2022
During the use of the optical transceiver module, various problems will inevitably occur. The following summarizes the main reasons and solutions in the event of failure. Matters needing attention before use 1. Do not connect optical modules with different wavelengths. Due to the different transmission loss and dispersion in the fiber, the transmission distance corresponding to different wavelengt...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Nov 15 , 2022
The technology of simultaneously transmitting information of two or more optical wavelength signals through different optical channels in the same fiber is called wavelength division multiplexing (WDM). WDM (Wavelength Division Multiplexing) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer, and c...
