NOKIA (Alcatel) compatible QSFP-100G-LR4 Description
QSFP-100G-LR4 is the Nokia (Alcatel-Lucent) part number for a 100GBASE-LR4 QSFP28 transceiver. The EdgeOptic 100G-QSFP28-10 is a compatible alternative that works over duplex single-mode fiber with a minimum guaranteed optical path loss budget of 6.3dB per IEEE 802.3ba, supporting distances up to 10km over OS2 (G.652.D) fiber. The module uses a duplex LC/UPC connector and is EEPROM coded for Nokia SR OS recognition.
The transmitter uses four EML (Electro-absorption Modulated Laser) channels at LAN WDM wavelengths: 1295.56, 1300.05, 1304.58, and 1309.14nm. The receiver uses a PIN photodiode array. Each channel runs at 25.78125 Gbps with NRZ modulation for an aggregate line rate of 103.125 Gbps. Per-lane transmit power is –4.3dBm to +4.5dBm, and per-lane receiver sensitivity is –10.6dBm at BER 5×10⁻⁵ (pre-FEC). The receiver overload point is –1.3dBm per lane.
The QSFP-100G-LR4 is used on Nokia SR OS platforms including the 7750 SR (Service Router), 7250 IXR (Interconnect Router), and 7950 XRS (Extensible Routing System) series. Any Nokia platform with QSFP28 ports that lists QSFP-100G-LR4 in its supported transceiver table can use this module. The EdgeOptic compatible is tested on current SR OS releases and coded with Nokia-specific EEPROM data.
Nokia uses several part number formats across its product lines. QSFP-100G-LR4 is the standardized transceiver designation used in Nokia’s optics ordering guides. The internal product code q28lr4d also maps to this module in Nokia inventory systems. Other Nokia 100G LR4 part numbers may carry different EEPROM identifiers — check the specific part number against your platform’s supported optics list before ordering.
DDM/DOM optical diagnostics are supported per the QSFP28 management interface (SFF-8636). The module reports per-lane TX and RX optical power, laser bias current, temperature, and supply voltage. It is compliant with the QSFP28 MSA (SFF-8665 form factor, SFF-8636 management interface) and IEEE 802.3ba 100GBASE-LR4. Classified as Class 1 laser safe per IEC 60825-1, CE and RoHS certified, with a commercial operating temperature range of 0°C to 70°C. Maximum power consumption is 3.5W.
The QSFP-100G-LR4 operates over standard OS2 single-mode fiber using duplex LC connectors. The minimum recommended link length is 2 meters. For links shorter than 2 meters, an inline optical attenuator is recommended to avoid receiver saturation. The module supports hot-swappable insertion in QSFP28 cages.

Frequently Asked Questions
What is q28lr4d?
q28lr4d is a Nokia internal product code that maps to the QSFP-100G-LR4 transceiver in Nokia inventory and ordering systems. The standard part number for ordering is QSFP-100G-LR4.
Which Nokia platforms support QSFP-100G-LR4?
The QSFP-100G-LR4 is supported on Nokia 7750 SR, 7250 IXR, and 7950 XRS series with QSFP28 ports. Check your platform model and SR OS release in Nokia’s supported transceiver list.
What is the difference between QSFP-100G-LR4 and other Nokia 100G LR4 part numbers?
Nokia uses multiple internal part number formats for the same optical specification. The QSFP-100G-LR4 designation appears in Nokia’s standardized optics guides, while other codes (3HE-prefixed hardware numbers) are used in different ordering contexts. Check which part number your platform lists as supported before ordering.
Does the compatible QSFP-100G-LR4 work natively on Nokia SR OS?
The EdgeOptic module is coded with Nokia-specific EEPROM data and has been tested on Nokia SR OS platforms. SR OS recognizes compatible transceivers that carry the correct vendor identification. Confirm compatibility with your SR OS release and platform before deployment.
