About NEM Engine

NEM Engine Technology Co., Ltd. is a leading provider of high-speed optical and copper interconnect solutions, serving data centers, enterprise networks, and next-generation infrastructure.

Engineered for Performance & Reliability

NEME’s NM-280-RJ45 Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) and are fully compatible with IEEE Std 802.3 standards including 10Gbase-T, 5Gbase-T, 2.5Gbase-T, and 1000base-T.

Our Direct Attach Cables (DAC) are built to withstand harsh operating conditions—temperature, humidity, and EMI interference—ensuring stable, high-speed connections across demanding environments.

With a focus on low power consumption and hot-swappable design, our passive copper cable assemblies offer an economical solution for within-rack and rack-to-rack applications.

Frequently Asked Questions

What is a DAC cable?

A Direct Attach Cable (DAC) is a twinax copper cable with fixed connectors on each end, used for high-speed interconnects in data centers. It is cost-effective and low-power for short-reach applications.

What is the difference between DAC and AOC?

DAC uses copper for electrical signal transmission and is ideal for short distances (up to 7m). AOC uses optical fiber between connectors, enabling longer reaches (up to 100m) with immunity to EMI.

Are NEM Engine products MSA compliant?

Yes, all NEM Engine transceivers and cables comply with relevant MSA standards, ensuring compatibility with major networking equipment brands.

Can I use a 10G SFP+ DAC with a 1G switch port?

No, DAC cables are designed for specific data rates. A 10G SFP+ DAC requires a 10G-capable port. However, some switches support speed negotiation.
