Benefícios de Módulo óptico 100GBASE QSFP28 DWDM PAM4
Adicionar mais links de 100G à fibra existente
Cada transceptor carrega um sinal 100G PAM4 em um comprimento de onda DWDM dedicado.
Vários comprimentos de onda podem compartilhar o mesmo par de fibras por meio de um multiplexador DWDM compatível, aumentando a capacidade total sem instalar um par de fibras separado para cada serviço de 100G.

Reduza a complexidade da rede de longo curso
O módulo QSFP28 produz um sinal óptico 100G de comprimento de onda único que pode se conectar diretamente à infraestrutura DWDM passiva suportada.
Esta abordagem compacta pode reduzir a necessidade de transponders separados em projetos de rede compatíveis e simplificar o espaço em rack, cabeamento e planejamento de energia.

Suporte a conexões metropolitanas e de alcance estendido
O transceptor suporta links de até 80 km quando o orçamento óptico e os limites de dispersão são satisfeitos.
Com amplificação EDFA e equipamento DCM selecionados corretamente, um sistema DWDM projetado pode estender a distância total do link até 120 km.

Escolha Conectividade LC ou CS com economia de espaço
O Duplex LC se encaixa em sistemas de patches ópticos amplamente implantados, enquanto o duplex CS fornece um espaço de conector menor para painéis de alta densidade compatíveis.
As duas opções de interface ajudam os projetistas de rede a combinar o módulo com os requisitos de densidade existentes ou futuros.

Simplifique a implantação de vários fornecedores
A codificação de firmware personalizada pode ser preparada para switches, roteadores e plataformas de transporte especificados.
A codificação correta ajuda o equipamento host a reconhecer o módulo e reduz os problemas de compatibilidade durante a instalação e substituição.

Módulo óptico 100GBASE QSFP28 DWDM PAM4 Guia de Seleção
How to Select a 100G DWDM QSFP28 Transceiver
Confirm the host interface: Verify that the switch, router or transport platform supports 100G QSFP28 PAM4 DWDM operation.
Choose the DWDM channel: Assign a matching wavelength for each end of the point-to-point link and coordinate all channels with the DWDM multiplexer plan.
Select the connector: Choose duplex LC for common optical patching systems or duplex CS for compatible high-density infrastructure.
Measure the route: Confirm the fiber length, fiber attenuation, connector loss, splice loss and passive DWDM insertion loss.
Calculate the optical budget: Compare total link loss with transmitter power, receiver sensitivity and receiver overload limits while retaining an engineering margin.
Check chromatic dispersion: Calculate accumulated dispersion at the selected wavelength and add a suitable DCM when the route exceeds the supported dispersion tolerance.
Plan optical amplification: For extended links, position compatible EDFA equipment according to the link design and verify that amplifier noise and output power remain acceptable.
Confirm equipment compatibility: Provide the host manufacturer, exact model and software version for the correct firmware coding.
Check the environment: The referenced modules are specified for commercial operation from 0 to 70°C.
How to Install a 100G DWDM QSFP28 Transceiver
Wear an anti-static wrist strap and verify the host compatibility, DWDM wavelength, connector type and link design before installation. Confirm that the transceivers at both ends use the same assigned channel, then keep the module latch closed, align the QSFP28 module with the port and gently push it into place until fully seated. Do not touch the optical interface or force the module into the host port.
Clean and inspect the duplex LC or CS connectors before connecting the transmit and receive fibers through the correct DWDM multiplexer ports. Install any specified EDFA, DCM and optical attenuator according to the approved link plan. After power-up, verify host recognition, wavelength routing, transmit and receive optical power, FEC status, link stability and error counters. Keep dust caps installed whenever a module or fiber connector is disconnected.

Módulo óptico 100GBASE QSFP28 DWDM PAM4 FAQ
What is a 100G DWDM QSFP28 PAM4 transceiver?
It is a hot-pluggable optical module that converts a 100G electrical interface into a single-wavelength PAM4 optical signal for transmission through a compatible DWDM network.
What is the maximum transmission distance?
The referenced transceiver models support links up to 80km when the optical budget and dispersion conditions are satisfied. A complete system can reach up to 120km when correctly engineered with compatible EDFA and DCM equipment.
Does the transceiver alone provide a 120km link?
No. The 120km figure applies to a complete engineered optical system. It normally requires suitable amplification, dispersion compensation, passive DWDM components and a verified end-to-end link budget.
What is the difference between the LC and CS versions?
Both versions carry the same type of 100G DWDM PAM4 signal. Duplex LC is widely used in existing fiber systems, while duplex CS offers a smaller connector footprint for compatible high-density patching equipment.
Can multiple 100G links share one fiber pair?
Yes. Each link uses an assigned DWDM wavelength, and compatible DWDM multiplexers combine multiple wavelengths onto the same fiber pair. The channel plan and optical budget must be checked for the complete system.
Are EDFA and DCM always required?
No. Their use depends on fiber length, total insertion loss, accumulated chromatic dispersion and the required system margin. An optical-link calculation must determine whether amplification or dispersion compensation is needed.
Can the module be coded for my switch or router?
Yes. Custom compatibility coding is available. Provide the equipment manufacturer, exact model and software or firmware version before ordering.
Can a long-reach DWDM module be used on a short link?
Only after checking the receiver overload limit and total link loss. An optical attenuator may be required when the received power is too high.
Why does the 100G DWDM link remain down after installation?
Check host compatibility, port configuration, FEC requirements, wavelength assignment, MUX/DEMUX channel routing, LC or CS transmit/receive direction, connector cleanliness, optical power, EDFA direction and DCM placement.
What information is required for a quotation?
Please provide the quantity, host equipment brand and model, DWDM channel or wavelength, connector type, fiber distance, passive component losses, EDFA and DCM requirements, operating temperature, OEM labeling needs and delivery destination.
