* O-Band (1310 nm) — up to 30 km without optical amplifiers. Reduces 5-year TCO by up to 80% vs C-Band with amplification.

  • Plug directly into QSFP-DD port of any router or switch — no external transponder chassis
  • Up to 65% lower backbone investment vs. traditional transponder-based DWDM architectures
  • SRD programs wavelength on-site in minutes — no factory reconfiguration or vendor lock-in
  • Interoperability tested with 3 different manufacturers in Salumanus fiber lab

Why GBC Photonics

What sets our modules apart

SRD-programmed for your vendor
Each module is individually programmed and tested with Smart Recode Device before shipment. Not a generic module from a warehouse.
5-year warranty + advance replacement
Better than most OEM warranties. Advance hardware replacement included — next-business-day in EU. No sending back and waiting.
EU warehouse, 24h shipping
Stock held in EU for same-week delivery across Poland, DACH, Benelux, and Nordics. No customs delays, no VAT complications.
24/7 EU engineering support
Direct access to network engineers, not a helpdesk. 4-hour response time. Remote diagnostics via SRD — no site visit needed.
Common questions

FAQ

Does using a third-party module void my switch warranty?

No. EU regulations and manufacturers' own published guidelines confirm that network equipment warranty is not voided by using MSA-compliant third-party transceivers. GBC Photonics modules are fully MSA-compliant and ISO 9001:2015 certified.

How do you guarantee compatibility with my specific switch model?

Every module is programmed using SRD (Smart Recode Device) and tested in the target switch environment before it leaves our EU warehouse. You also receive a 30-day free trial with two-way shipping — zero risk.

What happens if a module fails in production?

Advance hardware replacement is included in the 5-year warranty. We ship a replacement before you return the faulty unit. EU engineering team responds within 4 hours, and remote diagnostics via SRD often resolve issues without swapping hardware at all.

Can I get a free test unit before committing?

Yes. We offer a 30-day free trial with two-way free shipping for qualified B2B customers. No commitment, no credit card. Fill in the form below and our engineer will contact you within 24 hours.
