If you’ve ever stared at terms like “SFP”, “QSFP28”, or “800G Transceiver” while sourcing optical modules, you’re not alone—navigating these model names can feel like decoding a secret language. As a leading manufacturer of optical transceiver modules, Trixon (Sichuan Trixon Communication Technology Corp.,Ltd.) has helped 50+ telecom and industry clients across 56 countries cut through this confusion. Let’s break down the “family tree” of optical transceivers, so you can pick the right fit for your project.

Optical transceiver model names follow a simple logic (once you know the code):

• Letters: Refer to form factor (size) and channel count:
  • SFP = Small Form-factor Pluggable (compact, 1 channel)
  • SFP+ = Enhanced SFP (faster, 1 channel)
  • QSFP = Quad Small Form-factor Pluggable (4 channels)
  • QSFP28 = QSFP with 25G-per-channel speed (4 channels = 100G total)
• Numbers: Indicate total speed (e.g., “400G Transceiver”) or per-channel speed (e.g., QSFP28 = 25G/channel).

Trixon’s product range (155M~800G) covers all these core form factors—so whatever code you need, we’ve got a certified option.

To simplify your choice, here’s how Trixon’s key models stack up:

All Trixon modules meet international standards (UL, TUV, FCC, CE, RoHS) and are backed by ISO14001/9001/45001 certifications—so quality is non-negotiable.

Match the transceiver to your use case (Trixon supports all these sectors):

• SFP Transceiver: Ideal for Telecom Networks (FTTx/LTE) and Security Monitoring (Trixon’s core markets) — its long distance (up to 120km) works for outdoor/remote deployments.
• SFP+ Transceiver: Perfect for Enterprise LANs and Smart Grid — balances speed (10G) and cost for mid-sized networks.
• QSFP28 Transceiver: The go-to for Data Centers (cloud/enterprise) — 100G speed handles high-density server connections.
• 400G/800G Transceivers: For AI/Supercomputing Data Centers and large CATV networks — Trixon’s 800G modules support the latest high-bandwidth demands.

With over 15 years in the industry, Trixon combines:

• A full 155M~800G product portfolio (covering every model in this “family tree”)
• Global support (headquarters in Chengdu, branches in Beijing, Hangzhou, Shenzhen, Hong Kong, and the US)
• Unbeatable prices without compromising certified quality
