100GBASE-LR4 QSFP28 Compatible Transceiver Description
EdgeOptic's 100G-QSFP28-10 is a 100GBASE-LR4 QSFP28 transceiver designed for 100 Gigabit Ethernet links over single-mode fiber. The module multiplexes four LAN-WDM optical lanes at 25.78125 Gbps each (NRZ modulation) onto a single LC duplex pair, for an aggregate line rate of 103.125 Gbps (100 Gbps usable payload after 64B/66B encoding). The platform also supports OTU4 (4I1-9D1F per ITU-T G.959.1) at 111.81 Gbps on the same wavelength plan. A single SKU covers both 100G Ethernet uplink and OTN client-side roles. Codeable for over 80 vendor host platforms with vendor-recognized EEPROM.
The 100G-QSFP28-10 uses LAN-WDM technology with four discrete wavelength channels at 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm. The transmitter is built on an EML (Electro-absorption Modulated Laser) array with a PIN photodiode array on the receive side. This optical architecture enables full-duplex 100G transmission over a single fiber pair by multiplexing the four channels within the 1310 nm wavelength window.
The 100G-QSFP28-10 carries a 6.3 dB guaranteed optical link budget, supporting reach up to 10 km on G.652 single-mode fiber. Actual reach depends on installed fiber attenuation and connector loss; the 10 km figure assumes industry-typical attenuation against the guaranteed budget. The duplex fiber configuration reduces cabling-infrastructure cost versus parallel single-mode (PSM4) alternatives at the same data rate.
The 100G-QSFP28-10 is a hot-pluggable QSFP28 module with a duplex LC/UPC optical interface. The electrical interface conforms to SFF-8636 and SFF-8665 MSA specifications for compatibility with standard QSFP28 host systems across multi-vendor equipment platforms. The module is coded with vendor-recognized EEPROM for over 80 equipment brands.
The module reports DDM/DOM (Digital Diagnostic Monitoring) telemetry per SFF-8636, including TX/RX optical power per lane, case temperature, laser bias current, and supply voltage. The QSFP28 has no internal FEC engine but is fully transparent to host-side RS-FEC (IEEE 802.3bj Clause 91), which runs in the switch or router ASIC. The module operates within a 0 to 70°C case temperature range on a single 3.3 V supply with maximum power consumption of 3.5 W.
Standards compliance covers IEEE 802.3ba 100GBASE-LR4, IEEE 802.3bm CAUI-4, QSFP28 MSA SFF-8665, and SFF-8636 management interface. Multi-vendor interoperability is achieved through MSA adherence; equipment with vendor-specific module validation may require custom EEPROM programming. The module carries CE marking, RoHS-6 compliance, and Class 1 laser safety classification (FDA 21 CFR 1040, IEC 60825-1).
Typical applications include data center site interconnects, ISP backbone and aggregation networks, mobile operator core and backhaul, and enterprise campus links. The LAN-WDM design delivers a balance between reach capability and fiber-utilization efficiency for 10 km deployments.

Frequently Asked Questions
What is 100GBASE-LR4?
100GBASE-LR4 is an IEEE 802.3ba standard for 100 Gigabit Ethernet transmission over single-mode fiber using four LAN WDM wavelength channels around 1310 nm. Each channel carries 25.78125 Gbps with NRZ modulation for an aggregate line rate of 103.125 Gbps. The standard specifies a maximum reach of 10 km over OS2 fiber with a 6.3 dB link budget. The QSFP28 form factor uses a duplex LC connector.
What is the difference between 100GBASE-LR4 and 100GBASE-SR4?
100GBASE-LR4 uses four LAN WDM wavelengths over duplex single-mode fiber with LC connectors and reaches 10 km. 100GBASE-SR4 uses four parallel lanes over multimode fiber with MPO connectors and reaches 100m over OM3 or 150m over OM4. They require completely different fiber infrastructure and are not interchangeable.
What is 100GBASE-LR4 link budget?
The minimum optical link budget is 6.3 dB per IEEE 802.3ba. This supports distances up to 10 km over OS2 (G.652.D) single-mode fiber with standard connector losses. Actual reach depends on your fiber attenuation and installed connector quality.
Does 100GBASE-LR4 support FEC?
The QSFP28 module has no internal FEC engine. It is fully transparent to host-side RS-FEC (IEEE 802.3bj Clause 91), which runs in the switch or router ASIC. RS-FEC behavior is platform-dependent. Some switches enable it automatically, others require explicit configuration. Check your platform documentation.
Which vendors does the 100G-QSFP28-10 support?
The 100G-QSFP28-10 is an MSA-compliant base module that can be programmed with vendor-specific EEPROM coding for over 80 equipment brands including Cisco, Juniper, Arista, Nokia, Huawei, Ciena, Fortinet, and others. Select the vendor-coded version on the product page or contact our sales team for custom coding.
Does the 100G-QSFP28-10 support OTU4?
Yes. The platform is dual-rate, supporting both 100GBASE-LR4 (103.125 Gbps Ethernet) and OTU4 4I1-9D1F per ITU-T G.959.1 (111.81 Gbps OTN client) on the same LAN-WDM wavelength plan. A single SKU covers both 100G Ethernet uplinks and OTN client-side transport, depending on host platform configuration.
