Huawei QSFP28-100G-LR4-DM

Huawei 100G LR4 QSFP28 Transceiver (QSFP28-100G-LR4-DM)

This is a high-speed, long-range optical transceiver used for networking equipment. Think of it as a specialized "module" that plugs into a switch or router to send and receive data at extremely high speeds over fiber optic cables.

In a nutshell:

• It's Extremely Fast: Supports 100 Gigabit (100G) data rates.
• It's Long-Range: Uses Single-Mode Fiber (SMF) to transmit data up to 10 kilometers (about 6.2 miles).
• It's a Standard Form Factor: Uses the common QSFP28 plug, which fits into standard 100G ports on switches and routers.
• Wavelength: Uses four lanes of light at the 1310nm wavelength (the "LR4" and "DM" indicate this).

Key Specs at a Glance:

• Data Rate: 100 Gbps
• Standard: 100GBase-LR4
• Form Factor: QSFP28
• Fiber Type: Single-Mode (SMF)
• Max Distance: 10 km
• Wavelength: 1310 nm
• Connector: Duplex LC

Good for:

• Connecting high-performance switches in a data center.
• Creating long-distance links between buildings or campuses.
• High-speed backbone connections in a network.

Bottom Line: This is a professional, carrier-grade component used to build high-capacity network infrastructure. It is not for consumer use.

Note: Compatibility is key. This module is designed for Huawei networking equipment and may not work in switches from other brands like Cisco or Juniper without bypassing compatibility checks.
