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

Cisco Fiber Optic Module GLC-BX-U
The Cisco Fiber Optic Module GLC-BX-U is a 1 Gigabit Bi‑Directional (BiDi) SFP transceiver that enables duplex signaling over a single strand of single‑mode fiber (SMF). It operates as the "U" (upstream) side of a paired link transmitting at 1310 nm and receiving at 1490 nm and must be paired with a GLC-BX-D (downstream) module to complete the connection.
Cisco Fiber Optic Module GLC-LH-SM
The Cisco GLC-LH-SM is a Small Form-Factor Pluggable (SFP) transceiver module designed for Gigabit Ethernet applications. It operates at a wavelength of 1310 nm and supports data rates of 1Gbps over single-mode fiber (SMF) for distances up to 10 km, making it suitable for long-distance connections such as building-to-building or data center links.
Cisco Fiber Optic Module X2-10GB-SR
The Cisco X2-10GB-SR is an optical transceiver module designed to provide 10 Gigabit Ethernet connectivity over short distances using multimode fiber (MMF). It is built on the X2 form factor, which was widely used in earlier generations of Cisco hardware for 10GbE connections. Compared to newer form factors like SFP+, the X2 module is physically larger and consumes more power, but it remains an essential component for organizations maintaining legacy Cisco networking equipment.
Cisco Module GLC-TE
The Cisco Module GLC-TE is a copper-based Gigabit Ethernet SFP transceiver, not a fiber optic module. It provides 1000BASE-T connectivity over standard twisted-pair copper cables (Cat5e or higher) with an RJ-45 connector, supporting speeds of 10/100/1000Mbps and distances up to 100 meters.
