Juniper compatible QSFP-100G-4WDM40 Description
EdgeOptic's QSFP-100G-4WDM40 compatible is a Juniper-coded 100GBASE-4WDM-40 QSFP28 transceiver built to the 4WDM-40 MSA. It mirrors Juniper OEM part QSFP-100G-4WDM40 (740-093290) for 100 Gigabit Ethernet links up to 40 km on a single duplex pair of G.652 single-mode fiber. The module is qualified by Juniper as a Common Optic, so it appears across 65 supported platforms in the Juniper Hardware Compatibility Tool covering routing, switching, and security.
Optical layer uses four LAN-WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, each carrying 25.78125 Gb/s NRZ. Cooled EML transmitters land between -2 dBm and +4 dBm per lane, and APD receivers reach -21 dBm sensitivity with -1 dBm overload. Optical link budget is 22 dB with host-side RS-FEC engaged for the full 40 km reach, or 18 dB without FEC. Host RS-FEC is required for the 40 km application; the host platform must terminate FEC on the line side.
Protocol scope is 100GE only. The 4WDM-40 MSA defines a 100GBASE application with KR4 FEC and does not extend to OTU4 or Fibre Channel rates, so this module is not a substitute for OTU4 line-side or 32GFC/128GFC ports. For dual-rate transponder applications on the same root family, see the OTU4-suffix and Fibre Channel SKUs that ride the broader 100G-QSFP28-40 envelope.
Compatible Juniper platforms (per the Juniper HCT) include MX204, MX240, MX480, MX960, MX2008, MX2010, MX2020, MX10003, MX10004, MX10008, MX10016, PTX10003, PTX10004, PTX10008, PTX10016, PTX10001-36MR and PTX10002-36QDD on the routing side; QFX5120-32C, QFX5130-32CD, QFX5130-48C, QFX5130-48CM, QFX5210-64C, QFX5220-32CD, QFX5240-64QD and QFX5700 on the switching side; ACX710, ACX5448, ACX7024, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348 and ACX7509 on the access side; and SRX4700 on the security side. Verify the line-card or port-cage entry against the Juniper HCT for any platform before deployment.
EEPROM is programmed for Juniper recognition, so the optic registers cleanly in Junos with no third-party transceiver flag and no override CLI. Digital Optical Monitoring is supported and reports temperature, supply voltage, laser bias current, transmit optical power, and per-lane receive power through the standard QSFP28 SFF-8636 page map. Form factor is QSFP28 duplex LC PC/UPC; module power draw is 4.5 W maximum; commercial operating temperature 0 to +70 C.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty included. For Juniper-specific platform validation against your Junos release, contact our sales team.
Frequently Asked Questions
Does the QSFP-100G-4WDM40 require any Junos override or third-party-transceiver setting on MX or PTX series?
No. The EEPROM is programmed for Juniper recognition, so Junos accepts the module on MX and PTX platforms with no override command and no unsupported-transceiver flag. Bring up the interface as you would with the Juniper-branded part. If a specific platform-and-Junos combination has a port-level FEC requirement, confirm the FEC mode on the host port matches the 4WDM-40 host-RS-FEC application before committing the link.
Can a QSFP-100G-4WDM40 interoperate with a 100GBASE-4WDM-40 module from another vendor on the far end?
Yes, when both ends are 4WDM-40 MSA-compliant and host RS-FEC is enabled, a Juniper-coded 4WDM-40 will pair with another vendor's 4WDM-40 over the same 40 km SMF span. Confirm that the far-end module's link-budget and FEC profile are aligned; a 4WDM-40 module and an ER4 Lite module may interoperate when host RS-FEC is enabled, but this is not universal. Verify against the far-end vendor's compatibility documentation before deployment.
