Juniper compatible QSFP-100GBASE-LR4 Description

EdgeOptic's QSFP-100GBASE-LR4 compatible is a Juniper-coded 100GBASE-LR4 QSFP28 transceiver, built on our 100G-QSFP28-10 hardware platform with Juniper-recognised EEPROM programmed at the factory. QSFP-100GBASE-LR4 is the original Juniper ordering code (older Juniper Optics naming style, before Juniper standardised on QSFP-100G-LR4-x); the matching Juniper internal stockroom number is 740-058732. Older BOMs, RFQs and inventory systems built around platforms deployed pre-2018 frequently still call out QSFP-100GBASE-LR4, so the part number remains a live ordering reference for spare-stocking those installations. The Juniper Hardware Compatibility Tool lists QSFP-100G-LR4-C as the Common Equivalent of QSFP-100GBASE-LR4, indicating both ordering codes describe the same Ethernet-only optical specification.

Optically the module is IEEE 802.3ba Clause 88 100GBASE-LR4. An EML transmitter array drives four LAN WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm, each carrying 25.78125 Gbps NRZ for an aggregate line rate of 103.125 Gbps. A passive multiplexer combines them onto one outbound fiber, and a PIN photodiode array recovers the wavelengths at the far end. The module provides a optical path loss budget of 6.3 dB, which supports 10 km over OS2 (G.652.D) single-mode fiber at typical plant attenuation. TX power is specified at -4.3 to +4.5 dBm, RX sensitivity is -10.6 dBm, and module power draw is roughly 3.5 W.

Per the Juniper HCT description, QSFP-100GBASE-LR4 supports Ethernet rate only (no OTU4 or other transport rates). There is no internal FEC engine; the optic is fully transparent to host-side RS-FEC (IEEE 802.3bj Clause 91) running in the connected Juniper platform ASIC. QSFP28 MSA (SFF-8665) and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current. The duplex LC/UPC connector pairs with standard SMF patch cords; the commercial 0 to 70 °C operating temperature range covers typical data-centre and central-office environments. For the canonical platform support list, consult the Juniper HCT model page for QSFP-100GBASE-LR4.

Frequently Asked Questions

What is Juniper internal part number 740-058732?

740-058732 is Juniper's internal (stockroom) part number for the QSFP-100GBASE-LR4 optical transceiver. Procurement and inventory systems often reference 740-058732 rather than the QSFP-100GBASE-LR4 marketing code; both resolve to the same module on the Juniper Hardware Compatibility Tool model page.

Is QSFP-100GBASE-LR4 still a current Juniper ordering code, or has it been replaced by QSFP-100G-LR4-C?

Both ordering codes are listed on the Juniper Hardware Compatibility Tool with QSFP-100G-LR4-C identified as the Common Equivalent of QSFP-100GBASE-LR4. QSFP-100GBASE-LR4 follows the older Juniper Optics naming style; QSFP-100G-LR4-C uses the newer QSFP-100G-LR4-x convention. Juniper has not marked QSFP-100GBASE-LR4 as end-of-life, so the original ordering code remains valid for legacy BOMs while QSFP-100G-LR4-C is the form Juniper uses for current catalogue references.

What is the difference between QSFP-100GBASE-LR4 and JNP-QSFP-100G-LR4?

Same optical specification, different Juniper naming conventions. QSFP-100GBASE-LR4 (Juniper internal 740-058732) follows the older Juniper Optics style. JNP-QSFP-100G-LR4 (Juniper internal 740-061409) follows the JNP-prefix convention. Both appear on the Juniper Hardware Compatibility Tool. Match the exact ordering code on the original BOM rather than substituting one form for the other when sourcing spares.

Does the EdgeOptic QSFP-100GBASE-LR4 compatible work natively on Junos?

Yes. EdgeOptic programs each unit with Juniper-recognised EEPROM, so Junos initialises the module without any allow-other-transceivers or third-party-allowed configuration command. The optic identifies as a Juniper QSFP-100GBASE-LR4 (740-058732) on show chassis hardware and on show interfaces diagnostics optics output.
