Use Case for 10G/40G Switch-to-Switch Interconnect

In addition to 10 GbE, the telecom market nowadays is also actively deploying 40 GbE connections to support server connectivity, the typical use case is switch-to-switch interconnects. In fact, copper cables are used in some special cases, primarily for switch-to-switch short-reach connections. However, with the majority of 40 GbE connections being optic fiber-based, fiber optic cables, especially the MTP/MPO cables…

C3KX-NM-10G Network Module Overview

Questions like whether a 1G SFP can be used on the SFP+ port of the switch and support 10G data rate are frequently asked by overall users. Generally, you will get the answer “no”. Because Most (95+%) SFPs and SFP+s will only run at the rated speed, no more, no less. Even though SFP and SFP+ have the same port…

Male-Female and Female-Female Fixed Fiber optic Attenuators

Introduction to Fiber Optic Attenuator

Fiber optic attenuators are often used to control the optical signal strength in fiber optic links. For example, in a DWDM based system, the DWDM employs multiple wavelengths and channels in different communication protocols and bit rates requiring precise tuning of the power levels of the channel signals. Fiber optic attenuators are often used to adjust the optical power signal…
