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.
