Extralink QSFP28 DAC CABLE 100G 1M 30AWG PASSIVE network transceiver module

The Extralink QSFP28 DAC CABLE 100G 1M 30AWG PASSIVE is a passive direct attach copper transceiver solution designed for short-reach high-speed links. With a QSFP28 interface and support for up to 100000 Mbit/s, the 1 meter length and 30AWG conductor provide a compact, flexible connection between switches, routers and servers in rack-to-rack and intra-rack environments. The cable requires no external power and is intended for reliable, low-latency links where active optical or longer-reach solutions are unnecessary.

Advantages

The cable delivers a stable 100G connection over a short distance with low latency and minimal power consumption due to its passive design. Its QSFP28 connector ensures compatibility with equipment that supports QSFP28, while the 30AWG construction offers a balance of signal integrity and flexibility for routing within dense racks. The compact one-meter length reduces excess cabling and helps maintain tidy installations.

Suitable for

• Short-distance 100G connections between switches and servers in data centers
• Rack-to-rack and intra-rack interconnects where low latency is required
• High-density network environments requiring compact, low-power cabling

Key specifications

• Interface: QSFP28
• Maximum data rate: 100000 Mbit/s (100G)
• Cable length: 1 m
• Conductor gauge: 30AWG
• Connector type: QSFP28 to QSFP28 direct attach copper
• Design: Passive (no active components)

How to use

Insert each QSFP28 connector into the corresponding QSFP28 ports on networking equipment, ensuring the latch engages securely. Route the cable to avoid excessive bending and mechanical strain; maintain the minimum bend radius appropriate for 30AWG copper assembly. The passive cable requires no configuration—once connected, devices will negotiate the link speed according to their capabilities and settings.

Recommendations

For optimal performance, use the cable within short-reach scenarios up to the specified 1 meter length and avoid environments with strong electromagnetic interference. Verify QSFP28 port compatibility on both ends before installation and handle the connectors by the housing to prevent damage to the contacts.
