Axiom

Axiom AXG99556 100GBASE-SR4 QSFP28 SFP transceiver 850 nm

SKU CH-VRHF-GMJWH MPN AXG99556

100 Gbit/s QSFP28 transceiver operating at 850 nm for short-range optical and data networking

  • 100 Gbit/s throughput for high-density 100GBASE-SR4 links
  • 850 nm VCSEL optics optimised for short-reach multimode fibre
  • QSFP28 form factor with 28 Gbit/s electrical lanes per channel
  • MSA-compliant coding ensures interoperability across OEM platforms
  • TAA-compliant build qualifies for government procurement requirements

What this module does and who uses it

The Axiom AXG99556 is a QSFP28 transceiver built for 100GBASE-SR4 optical links at 850 nm. It targets network engineers who need 100000 Mbit/s connectivity inside data centres or campus fabrics. The module is pre-coded for Ruckus E100G-QSFP28-SR4 gear and carries TAA compliance for regulated projects. Buyers who need single-mode reach or longer multimode distances should look elsewhere.

Practical limits of the SR4 interface

This transceiver follows the 100GBASE-SR4 standard over multimode fibre with an 850 nm wavelength. The interface uses four parallel lanes, each running at 28 Gbit/s, to reach the aggregate 100000 Mbit/s rate. Reach is constrained by the SR4 specification and the modal bandwidth of the installed OM3 or OM4 cabling. Links that exceed the supported distance or use single-mode fibre will not operate reliably.

Installation notes and common pitfalls

The QSFP28 form factor inserts directly into any MSA-compliant cage without tools. Each unit carries a unique serialisation that prevents address conflicts in dense chassis. The most frequent issue is a fibre polarity mismatch across the MPO connector; verifying the array alignment before locking the latch avoids a dark link. Dust caps should stay on until the moment of mating to keep the optical faces clean.

Questions about this item

Should I choose the 100GBASE-SR4 QSFP28 version or a different speed for my Ruckus switch?

This module is the 100GBASE-SR4 QSFP28 model pre-coded for Ruckus E100G-QSFP28-SR4, so select it when your switch requires 100G SR4 optics.

What does the 100000 Mbit/s headline figure deliver in a live network?

It provides a 100 Gbps lane rate over four parallel fibres at 850 nm, giving an aggregate 100 Gbps throughput in a real link.

The QSFP28 interface — what distance does it cap at with OM4 fibre?

The QSFP28 SR4 form factor supports up to 100 m on OM4 multimode fibre at 850 nm per MSA specifications.
