Juniper compatible QSFP-100G-LR Description

QSFP-100G-LR is the Juniper part number (FRU 740-096178) for a 100G single lambda QSFP28 transceiver operating at 10km over duplex single-mode fiber. This module replaces the traditional 4-wavelength LR4 design with a single PAM4 optical lane, delivering the full 100 Gbps per IEEE 802.3cu with RS-FEC.

The transceiver operates at 1310nm nominal (1304.5–1317.5nm, 100G Lambda MSA L0 channel) with an EML laser transmitter and PIN photodiode receiver. An integrated CDR retimes the PAM4 signal on both TX and RX paths. The module provides a 6.3 dB optical link budget supporting 10km reach over standard G.652 single-mode fiber with LC duplex connectors.

Juniper lists QSFP-100G-LR as a Common Optic, qualified across: QFX5120, QFX5130, QFX5220, QFX5700 switches; MX204, MX304, MX480, MX960, MX10003/10004/10008 routers; PTX10001, PTX10004, PTX10008 transport; and EX4650, EX9200 series. Minimum Junos release depends on the chassis and line card; verify against Juniper’s Hardware Compatibility Tool (apps.juniper.net/hct) before deployment.

This compatible module is coded with Juniper-recognized EEPROM data and requires no override commands — Juniper platforms do not block third-party transceivers by default. DDM/DOM diagnostics are accessible via “show interfaces diagnostics optics” and SNMP monitoring.

Built on the EdgeOptic 100G-QSFP28-SL10 platform and compliant with IEEE 802.3cu, the 100G Lambda MSA, and QSFP28 MSA (SFF-8636/SFF-8665). Carries Class 1 laser safety (IEC 60825-1), CE, and RoHS certifications, with maximum power consumption of 4.5W.

Single lambda 100G LR uses PAM4 modulation on one optical wavelength instead of the 4x25G NRZ architecture of traditional LR4. This simplifies module construction: one EML laser and one PIN photodiode replace LR4’s 4-channel mux/demux assembly, cutting power at volume. In exchange, electrical signal integrity is tighter and RS-FEC on the host is mandatory to clean up PAM4 bit errors.

Use cases include data center spine-leaf uplinks, cost-optimized metro interconnect, and 100G ports on modern switches where line card power density rewards the lower-power PAM4 design. Single lambda LR and 4-lambda LR4 do not interoperate; both ends of the link must run the same standard.

100G Lambda MSA-compliant modules require KP4 RS-FEC (Reed-Solomon 544,514) enabled on the host platform to meet the BER specification. Most modern 100G host ASICs include KP4 FEC natively for PAM4 interfaces, but legacy 100G line cards may only support the weaker FC-FEC used for LR4 NRZ. Verify host RS-FEC support before deploying single lambda modules.

Frequently Asked Questions

What is Juniper FRU 740-096178?

FRU 740-096178 is the Juniper field-replaceable unit part number for the QSFP-100G-LR, a single lambda 100G PAM4 QSFP28 transceiver. This number appears on the module label and in “show chassis hardware” output. It maps to QSFP-100G-LR in Juniper’s Hardware Compatibility Tool.

Is QSFP-100G-LR the same as a JNP-branded Juniper optic?

QSFP-100G-LR is classified as a Common Optic with broad platform support across QFX5120/5130/5220/5700, MX204/304/480/960/10003/10004/10008, PTX10001/10004/10008, and EX4650/9200 series. Minimum Junos release varies by chassis and line card — verify against apps.juniper.net/hct for your exact version. JNP-branded modules have more limited platform coverage.

Can QSFP-100G-LR interoperate with JNP-QSFP-100G-LR4?

No. QSFP-100G-LR (740-096178) uses single lambda PAM4 with built-in FEC. JNP-QSFP-100G-LR4 (740-061409) and QSFP-100GBASE-LR4 (740-058732) use four LAN-WDM wavelengths with NRZ modulation. The physical layer encoding and wavelength plans are completely different — both ends of a link must use the same standard.
