Cisco QSFP-100G-DR-S Module

Cisco QSFP-100G-DR-S Module:

The Cisco QSFP-100G-DR-S is a high-performance transceiver module engineered for deployment in enterprise and data center networks. As a member of Cisco’s 100 Gigabit Ethernet (100G) transceiver lineup, it delivers data transfer speeds of up to 100Gbps. “QSFP” stands for Quad Small Form-factor Pluggable, indicating the module’s design and interface, which includes four separate channels each supporting 25Gbps. The “100G” denotes its total data throughput capacity.

The “DR” refers to “Directly Attached Copper” meaning the module connects via copper cabling, making it ideal for short-range links and providing a more economical option than fiber. The “S” identifies it as a Cisco-specific version of the standard QSFP-100G-DR. In essence, this network module enables efficient, high-speed 100G Ethernet connections within modern network infrastructures. It’s ideal for short-distance fiber links inside large data centers, especially for connections between top-of-rack switches and spine switches.

Common network equipment Using QSFP-100G-DR-S are data center switches, routers, NIC and etc. This Cisco fiber optic module is really useful because of its High bandwidth (100G), Short reach (up to 500m over SMF) and Cost-effective for data centers already using single-mode fiber.

Features of Cisco QSFP-100G-DR-S Module:

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Speed: Supports 100Gbps data rate
• Connector type: Uses a single-mode fiber (SMF) with an LC connector
• Reach: Up to 500 meters over SMF
• Technology: Uses PAM4 modulation over a single optical wavelength (DR = “Data Center Reach”)
• “S”: Indicates it’s a Cisco-specific version
