Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

This BlueLAN direct attach cable delivers 100 Gbps over passive copper, linking QSFP28 ports across short 0.5 m runs in data centers and high-performance computing clusters.

Overview

The BlueLAN SC282801L0.5M30 is a passive copper QSFP28 to QSFP28 direct attach cable, built for 100 Gigabit Ethernet and InfiniBand EDR. It is compatible with Allied Telesis AT-QSFP28-0.5CU and other QSFP28-based equipment. The 30 AWG twinax construction and 100 Ohm impedance ensure signal integrity over 0.5 meters, while passive design keeps power consumption low and latency minimal.

What stands out

  • 100 Gbps data rate for high-bandwidth links
  • Hot-swappable QSFP28 connectors for easy installation
  • Passive copper design – no power draw, no cooling needed
  • Supports IEEE 802.3bj and InfiniBand EDR
  • Compact 0.5 m length reduces cable clutter in dense racks

Technical details

  • Connector type: QSFP28 to QSFP28
  • Cable type: Passive copper, 30 AWG
  • Data rate: 100 Gbps
  • Length: 0.5 m
  • Impedance: 100 Ohm
  • Operating temperature: 0°C to 70°C
  • Storage temperature: -40°C to 85°C

Our verdict

A reliable, low-cost 100G interconnect for short-reach QSFP28 deployments. Its passive design and exact compatibility with Allied Telesis AT-QSFP28-0.5CU make it a straightforward choice for high-density environments.
