Product Overview
The QSFP-100G-SR4-S is a high-speed 100 Gigabit Ethernet optical transceiver module designed for short-range transmission over multimode fiber (MMF). It supports link lengths up to 70 meters on OM3 fiber and 100 meters on OM4 fiber using MPO-12 connectors. Ideal for high-density data centers and enterprise network aggregation layers, this QSFP28 module complies with IEEE 802.3bm 100GBASE-SR4 standards and delivers efficient, scalable 100G connectivity.
Product Overview
The QSFP-100G-LR4-S is a high-performance 100 Gigabit Ethernet QSFP28 optical transceiver designed for long-distance data transmission over single-mode fiber (SMF). Supporting a maximum reach of 10 kilometers, it uses four CWDM channels in the 1310 nm range and multiplexes them into a single LC duplex output. This module is ideal for large-scale data centers, metro aggregation layers, and enterprise backbone networks requiring high-bandwidth, long-reach connectivity.
Product Details
The QSFP-100G-LR4-S complies with IEEE 802.3ba 100GBASE-LR4 and QSFP28 MSA standards. It uses four 25 Gbps lanes (CWDM) for both transmit and receive, providing an aggregate 100 Gbps full-duplex bandwidth. It features low power consumption, hot-pluggable design, and Digital Diagnostics Monitoring (DDM) for real-time performance tracking. This transceiver is widely compatible with major brands of switches, routers, and network interface cards.
