The Cisco QSFP28 Datasheet is an indispensable resource for anyone navigating the complexities of modern high-speed networking. This document provides critical technical specifications and operational details for Cisco's Quad Small Form-factor Pluggable 28 (QSFP28) transceivers, essential components for delivering 100 Gigabit Ethernet connectivity. Understanding the information within the Cisco QSFP28 Datasheet empowers network engineers and IT professionals to make informed decisions about deployment, compatibility, and performance optimization.
Understanding the Cisco QSFP28 Datasheet and its Applications
The Cisco QSFP28 Datasheet is essentially a comprehensive technical blueprint for these high-performance networking modules. It details everything you need to know about a specific QSFP28 transceiver, from its physical characteristics and electrical requirements to its optical performance and environmental tolerances. Think of it as the instruction manual and specification guide all rolled into one.
These datasheets are crucial for several reasons. Firstly, they outline the various types of QSFP28 transceivers Cisco offers, each designed for different applications and distances. This includes:
-
Short-reach modules (e.g., SR4) for data center interconnects.
-
Long-reach modules (e.g., LR4) for longer distances across campuses or metro networks.
-
Active Optical Cables (AOCs) and Direct Attach Copper (DAC) cables for very short, fixed connections.
Secondly, the datasheets specify the compatibility of these modules with different Cisco networking devices, such as switches and routers. This ensures that you select a transceiver that will function correctly with your existing infrastructure.
Properly utilizing the Cisco QSFP28 Datasheet is paramount to avoiding interoperability issues and ensuring the smooth operation of your network.
