Ixia NGY 10GbE Load Modules: The Complete LSM10GXM Family Guide — 106 Refurbished Modules In Stock
If you run an Ixia Optixia XM2, XM12, XG12, or XGS12 chassis, the NGY LSM10GXM family is the workhorse 10 Gigabit Ethernet load-module line you’re most likely to buy, replace, or expand. It’s also one of the most confusing product lines Ixia ever shipped: nearly two dozen part numbers that differ only by a letter or two — XM8-01 vs XM8S-01 vs XM8GBT-02 vs XM8NG-01 — with real differences in interface type, per-port CPU and memory, and Layer 2–7 capability hiding inside those suffixes.
This guide decodes the entire family, compares every variant we stock side by side, and helps you pick the right card for your test bed. We currently have 106 refurbished LSM10GXM modules in stock across 18 part numbers, every one fully tested, shipped with a comprehensive test report, and backed by a one-year warranty — with prices starting at $799.
How to Read an NGY Part Number
Every module in the family follows the same pattern: LSM10GXM + [R] + port count + [suffix] + revision.
- LSM10GXM — 10 Gigabit LAN Services Module, XM (High-Density) form factor. One chassis slot each.
- R (as in LSM10GXMR8-01) — Reduced performance: 400 MHz CPUs with 128 MB per port and reduced L2-3 feature support with limited L3 routing. Line-rate traffic generation at a fraction of the price — ideal for port-count-heavy L2 switching tests.
- Port count — 2, 3, 4, or 8 ports of 10GbE per slot.
- No suffix — base full-featured module: 800 MHz per-port CPUs, 512 MB per port, XFP optical interfaces, full Layer 2–7 support with the Linux SDK and L4-7 application support.
- S — SFP+ interfaces with 1 GB RAM per port and full L2-7 support. Accepts 10GBASE-SR, 10GBASE-LR, 10GBASE-LRM optics or SFP+ direct-attach copper.
- GBT — 10GBASE-T: native RJ45 copper 10GbE. If your device under test has copper 10G ports, this is the variant you need — no transceivers required.
- XP — Xtra Performance: upgraded CPUs with 1 GB per port for heavier per-port workloads.
- NG — Fusion-enabled next-generation cards (LSM10GXM4NG, LSM10GXM8NG) with SFP+ interfaces, built for Ixia’s Fusion architecture under IxNetwork and IxLoad.
- -01 / -02 — hardware revision.

Which NGY Should You Buy?
Testing optical 10G at scale on a budget → LSM10GXM8-01 (XFP) or LSM10GXM3-01. The 8-port XFP card gives you the most full-featured ports per dollar in the family, and at $799.99 the 3-port XM3-01 is the cheapest way to put full L2-7 10GbE test ports in a chassis, period. XFP optics are plentiful and cheap on the secondary market — we stock the adapters and transceivers too.
Modern SFP+ infrastructure → LSM10GXM8S-01 or LSM10GXM4S-01. Same full L2-7 capability, but SFP+ cages with 1 GB of RAM per port. These take the same 10GBASE-SR/LR optics and direct-attach cables as your production switches. This is the family’s sweet spot for most labs today.
Copper 10GBASE-T device under test → the GBT variants. Native RJ45 10G — no transceiver spend at all. The 8-port LSM10GXM8GBT-02 (14 in stock) is the density king here, in the Xtra Performance tier.
Pure L2/L3 forwarding, RFC 2544/2889 benchmarking, port count over per-port horsepower → the R (Reduced) line. Line-rate traffic generation with reduced L2-3 features and limited L3 routing, at roughly half the price of the full-featured equivalents. An R8 gives you eight line-rate 10G ports for less than many vendors charge for two.
IxNetwork/IxLoad Fusion environments → LSM10GXM4NG-01 / LSM10GXM8NG-01. The Fusion-enabled next-generation cards; if your methodology standardizes on Ixia’s converged Fusion architecture, these are the family’s top tier.
Need More Than 8 Ports per Slot? Or Layer 4-7?
The NGY family tops out at 8 ports per slot. If your bottleneck is raw port density, the Ixia Xdensity XDM10G32S packs 32 SFP+ ports of wire-speed 10GbE into a single slot — four times the density of an XM8S — and we have over 50 of those in stock as well; read our full XDM10G32S deep-dive for the trade-offs.
If your work is stateful Layer 4-7 application testing rather than L2-3 traffic, see our guide to the Xcellon-Ultra NP — and for L4-7 at full 10G line rate, ask us about the Optixia NGY-NP8-01 network-processor modules we also stock.
Why Buy Refurbished NGY From Us
Keysight ended new sales of the NGY line years ago, but tens of thousands of these cards remain the backbone of validation labs worldwide — which makes a deep, tested refurbished pool the practical way to expand or maintain an XM-chassis test bed:
- 106 modules in stock across 18 part numbers — one of the largest NGY inventories anywhere, so you can match your existing cards exactly or standardize spares across a whole lab.
- Every module is fully tested in our own Optixia chassis before shipping, and each unit ships with a comprehensive test report documenting port-by-port results.
- A full one-year warranty on every card.
- Prices from $799.99 — a fraction of what this capability cost new, and we offer volume pricing on multi-card orders.
Whether you’re adding ports to an existing XM12, building a regression rack from scratch, or hunting one exact part number to match a validated test bed, chances are it’s on our shelf and already tested.
Quantities shown are live inventory — popular variants like the XM3-01 and XM8GBT-02 move fast.
