Juniper compatible QSFP-100G-ER4L Description
QSFP-100G-ER4L is the Juniper part number for a 100GBASE-ER4 Lite QSFP28 transceiver. This EDGE compatible module matches the original Juniper specifications with EEPROM coded for Junos OS recognition. It operates over duplex single-mode fiber at four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, and 1309.14 nm), reaching up to 40 km with host FEC or 30 km without FEC.
The module uses EML transmitters and APD (Avalanche Photodiode) receivers, carrying four lanes at 25.78125 Gbps each for an aggregate 103.125 Gbps line rate. DDM/DOM provides real-time readings of TX/RX optical power, laser bias current, temperature, and supply voltage. Maximum power consumption is 4.5 W from a single 3.3 V supply. Operating temperature range is 0 to 70 °C.
The QSFP-100G-ER4L is supported on Juniper MX series (MX204, MX240, MX480, MX960, MX10003, MX10008, MX10016), PTX series (PTX1000, PTX5000, PTX10003, PTX10008), QFX series (QFX5220, QFX10002, QFX10008, QFX10016), and ACX series routers with QSFP28 ports. Juniper generally accepts third-party optics with correct EEPROM coding without requiring special CLI commands.
Juniper uses QSFP-100G-ER4L as its part number. The same ER4 Lite specification is listed as QSFP-100G-ER4L-S by Cisco and QSFP-100G-ERL4 by Arista. All are interoperable on the same fiber link, provided FEC is configured consistently on both ends.
Our compatible QSFP-100G-ER4L is CE and RoHS certified, QSFP28 MSA-compliant, and conforms to the 100GBASE-ER4 Lite specification. Before delivery, every module undergoes optical parameter measurement, connector cleanliness inspection, and EEPROM data validation testing.

Frequently Asked Questions
Which Juniper platforms support the QSFP-100G-ER4L?
The QSFP-100G-ER4L is supported on Juniper MX series (MX204 through MX10016), PTX series (PTX1000 through PTX10008), QFX series (QFX5220, QFX10002, QFX10008, QFX10016), and ACX routers with QSFP28 ports. Check the Juniper Hardware Compatibility List for your specific model and Junos version.
Is QSFP-100G-ER4L the same as Cisco ER4L-S or Arista ERL4?
Yes. All three are 100GBASE-ER4 Lite QSFP28 modules with comparable wavelengths, link budget, and reach. The naming differs by vendor: Juniper uses ER4L, Cisco uses ER4L-S, and Arista uses ERL4. They are interoperable on the same fiber link.
Do I need special commands for compatible optics on Juniper?
Juniper Junos OS generally accepts third-party optics with correct EEPROM coding without requiring special CLI commands. Our compatible module is programmed for Juniper platform recognition and operates as a plug-and-play replacement.
Does the QSFP-100G-ER4L require FEC for 40 km?
Yes. Without host FEC, the module reaches approximately 30 km. With FEC enabled, reach extends to 40 km. Configure FEC at the interface level and ensure the remote end matches.
