Free Budget Shipping  



Many items at NothingButSavings.com offer FREE Budget Shipping. Plus, as with many of our competitors which do offer free shipping, we don't ask you to spend a specified amount in order to qualify for FREE Budget Shipping.

How do I qualify for Free Budget Shipping?

1. Add the item(s) that qualifies for FREE Budget Shipping to your order's shopping cart.

2. If a product has our "Free Shipping" tag that item will qualify for FREE Buget Shipping regardless of its price.

3. Proceed to checkout and select Budget Shipping as your shipping option (items will take an additional 7-10 business days to ship).

4. Ship your item(s) to a valid U.S. address.

5. Then, complete your order. It's that simple!

6. FREE Budget Shipping excludes certain oversized and/or overweight items, and those products that do not include this tag.

Some items may be excluded:

If certain items in your shopping cart are not eligible for Budet Shipping then buedget Shipping will not be available and thus the offer for Free Budget Shipping will not apply.

Free Budget Shipping is not available for International orders.

General Information

This QSFP28 Loopback Module is designed for testing 100G ports in switches, NICs, and other QSFP28-equipped devices. It supports passive electrical loopback for verifying signal continuity, link stability, and port behavior without requiring active optics.

Test 100G QSFP28 Connections

The QSFP28 Loopback Adapter emulates 4-lane electrical testing for QSFP28 ports operating at 100Gbps, and supports 40GBASE and 100GBASE Ethernet. It is MSA compliant and meets IEEE 802.3 requirements for reliable performance and universal compatibility.

Accurate Signal Diagnostics

Perform electrical loopback testing for full 100G link verification. Ensure consistent signaling with 100Ω impedance and low jitter for stable, repeatable test results under real-world conditions.

For Enterprise Network Switches

Connect directly to QSFP28 ports on switches, routers, and NICs for inline port testing. Compact and low-power, it is an essential tool for network technicians and IT pros in data centers and edge or on-prem installations.
