Compatible QSFP28QSFP-DD optical modules Fiji supplier

QSFP28 and QSFP-DD modules are backward-compatible, high-speed optical transceivers suitable for 100G to 400G networks, and can be sourced from global distributors with shipping to Fiji. Module OverviewQSFP28 (Quad Small Form-factor Pluggable 28) supports 100G Ethernet using four 25G lanes, with CAUI-4 electrical interfaces. It can use multimode or single-mode optics, including SR4, LR4, and ER4, depending on distance requirements.

QSFP-DD (Quad Small Form-factor Pluggable Double-Density) doubles the electrical lanes compared to QSFP28, supporting 400G and 800G speeds while maintaining the same port density. QSFP-DD is backward-compatible with QSFP28 slots, allowing flexible upgrades without replacing existing hardware. Both module types are MSA-compliant and widely interoperable with major switch and router brands such as Cisco, Juniper, Huawei, and Arista.

Compatibility Considerations

Backward Compatibility: QSFP-DD modules can operate in QSFP28 ports, but the speed will be limited to 100G. Fiber Type: Ensure the module matches your fiber infrastructure (single-mode vs multimode). Connector Type: QSFP28 typically uses LC or MPO connectors; QSFP-DD may use MPO for parallel optics.

FE

C and Protocol Alignment: Verify Forward Error Correction (FEC) settings and switch compatibility to avoid link failures.

Sourcing Options for Fiji

While no Fiji-specific suppliers are listed in the web results, global distributors such as Pivotal Optics offer QSFP28 and QSFP-DD modules with international shipping. Other options include: LINK-PP: Offers MSA-compliant modules compatible with major brands. Cisco Authorized Resellers: Provide certified QSFP-DD modules optimized for Cisco switches.

Regional I

T Distributors: Contact distributors in Australia or New Zealand, as they often ship to Fiji. When sourcing, confirm the module's brand compatibility, warranty, and shipping options to Fiji. For cost-effective deployment, third-party MSA-compliant modules are often compatible with multiple switch vendors, but always verify with your network equipment documentation.

Recommendation

For Fiji-based deployment: Identify your network switch or router model and check supported transceiver types. Choose QSFP28 for 100G links or QSFP-DD for 400G/800G upgrades. Contact global distributors like Pivotal Optics or regional resellers in Australia/New Zealand for shipping to Fiji.

Verify FE

C, fiber type, and connector compatibility before purchase to ensure seamless integration. This approach ensures high-speed connectivity while maintaining flexibility for future network upgrades.
