Cisco compatible QSFP-100G-LR4-I Description
EdgeOptic's QSFP-100G-LR4-I compatible is a Cisco-coded version of the EdgeOptic 100G-QSFP28-10I multi-vendor 100GBASE-LR4 QSFP28 transceiver. The module runs over a pair of single-mode fibers through duplex LC/UPC connectors, with four independent 25 Gbps lanes multiplexed onto the transmit fiber and demultiplexed from the receive fiber using LAN WDM at 1295.56, 1300.05, 1304.58 and 1309.14 nm. Combined, the four lanes carry the full 103.125 Gbps data rate using NRZ modulation, and 100G Ethernet is the only supported application on this module.
The optical link budget is 6.3 dB average, covering the 10 km maximum distance over single-mode fiber quoted for this class. DML laser transmitters pair with PIN photodiode receivers on each lane, with average launch power specified from -4.3 to 4.5 dBm per lane, average receiver sensitivity from -10.6 to 4.5 dBm per lane, and a minimum extinction ratio of 4 dB. DDM diagnostics report per-lane transmit power, receive power, bias current, temperature and supply voltage, and the module supports the host FEC interface per its QSFP28 management; 100GBASE-LR4 meets IEEE 802.3ba's 10 km objective on its 6.3 dB budget without requiring FEC.
This module ships to an operating temperature range of -40C to +85C and draws a maximum of 3.5W at 3.3V. It is built on the 100G-QSFP28-10I platform, CE and RoHS certified, Class 1 laser safe per FDA and IEC 60825-1, and compliant with the QSFP28 MSA, SFF-8636, SFF-8665 and IEEE 802.3ba 100GBASE-LR4. Typical deployments include ISP fiber aggregation and backbone links, mobile operator core and backhaul networks, and data center site interconnects.
This module is Cisco-coded, so Cisco platforms that recognize the QSFP-100G-LR4-I ordering code accept it. Verify platform and software release support against the Cisco 100 Gigabit Ethernet Transceiver Modules Compatibility Matrix. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the module ships with a lifetime warranty.

Frequently Asked Questions
What is the difference between the Cisco QSFP-100G-LR4-I and QSFP-100G-LR4-S?
Cisco's own datasheet lists the QSFP-100G-LR4-S as the commercial-temperature ordering code, rated 0 to +70C, and the QSFP-100G-LR4-I as the industrial-temperature ordering code, rated -40 to +85C. Both are 100GBASE-LR4 QSFP28 modules with duplex LC connectors, 10 km reach over single-mode fiber, and the same published optical parameters in Cisco's datasheet table for transmit and receive power. EdgeOptic's compatible module on this page ships to the same -40C to +85C operating range Cisco documents for the OEM ordering code.
Which Cisco platforms support the QSFP-100G-LR4-I?
Cisco's own datasheet states that Cisco QSFP modules are supported on Cisco switches and routers, with per-platform detail maintained in the Cisco 100 Gigabit Ethernet Transceiver Modules Compatibility Matrix. Verify the exact platform and software release against that matrix before ordering.
