Why Not Use Raman Amplifier to Extend the CWDM Network Reach?

  In comparison with the long-haul DWDM network that uses the thermo-electric coolers to stabilize the laser emissions essential, the CWDM network is a more economical solution that features wider wavelength spacing, allowing the wavelength fluctuation of uncooled directly modulated laser diodes (DMLs). But on the other hand, the CWDM [ Continue reading…]

How to Install a QSFP28 Transceiver

  In recent years, QSFP28 transceivers have been highly favored by many Ethernet users. The modules are hot-swappable input/output (I/O) device that connect the system’s module port electrical circuity with either a copper or a fiber-optic network. Transceiver installation attaches great importance to the whole Ethernet connectivity. This article provides [ Continue reading…]

Comparison of Passive DWDM and Active DWDM System

DWDM (dense wavelength division multiplexing) technology is an ideal solution to address the capacity-hungry issue, which can simply fall into two types, passive DWDM and active DWDM. To greatly expand the bandwidth of the existing fiber system, both passive DWDM and active DWDM systems are designed to multiplex different wavelengths [ Continue reading…]

BiDi Fiber Optic Transceiver Overview

  As we all know, common optical transceivers, like SFP+, SFP, normally require two fibers to achieve data transmission between switches, firewalls, servers, routers, etc. The first fiber is dedicated to receiving data from networking equipment, while the other is to transmit data to the equipment. With the development of [ Continue reading…]
