QSFP-100G-ER4L-S Cisco 100GBASE QSFP Transceiver, 40KM, SMF, Duplex LC
QSFP-100G-ER4L-S Cisco 100GBASE-ER4L QSFP Transceiver Module for SMF up to 40KM
Long-Reach 100G QSFP Optical Transceiver for High-Density Networking Over Single-Mode Fiber
The Cisco QSFP-100G-ER4L-S is a high-performance, hot-pluggable 100G QSFP28 optical transceiver designed for long-distance 100 Gigabit Ethernet applications. With support for transmission over single-mode fiber (SMF) up to 40 kilometers, it is an ideal choice for data center interconnect (DCI), metro backbone, enterprise WAN, and carrier-grade networks.
Engineered for reliability and efficiency, this 100G transceiver delivers line-rate 100 Gbps performance using four CWDM lanes (1295.56–1309.14 nm) and features Digital Optical Monitoring (DOM) for real-time link diagnostics. Its low power consumption (<4.5W) and hot-swappable design make it highly efficient and easy to deploy in scalable, high-density environments.
The QSFP-100G-ER4L-S is fully compliant with IEEE 802.3bm, IEEE 802.3ba, and MSA standards, ensuring seamless interoperability with Cisco switches, routers, and third-party equipment.
Enhance your network backbone with the Cisco QSFP-100G-ER4L-S — a cost-effective, long-haul 100G optical solution for today’s high-bandwidth demands.

FAQs for QSFP-100G-ER4L-S:
What is the maximum distance supported by the QSFP-100G-ER4L-S module?
It supports up to 40 km transmission distance over single-mode fiber (SMF) without the need for additional amplification.
Is the QSFP-100G-ER4L-S compatible with standard Cisco 100G ports?
Yes, it is compatible with Cisco switches and routers that support QSFP28 100G ports and comply with the 100GBASE-ER4L standard.
What kind of fiber and connector does this transceiver require?
It uses duplex LC connectors and requires single-mode fiber (SMF) cabling.
Does it support Digital Optical Monitoring (DOM)?
Yes, the module supports DOM, which allows monitoring of optical parameters such as transmit/receive power, temperature, and voltage.
Can this module be used for shorter distances?
While optimized for up to 40 km, it can be used for shorter distances with appropriate optical attenuation if necessary to prevent signal saturation.
