Description

The JNP-QSFP-100G-SR4-BCC is a drop-in compatible replacement for the Juniper JNP-QSFP-100G-SR4. This QSFP28 transceiver is plug-and-play compatible with Juniper network platforms requiring 100GBASE-SR4 optical interfaces. - IEEE 802.3bm 100GBASE-SR4 compliance guarantees interoperability with standards-compliant QSFP28 ports across data center and enterprise switching infrastructure - QSFP28 form factor with four independent 25 Gbps channels delivering 100 Gbps aggregate throughput over multi-mode fiber at 850nm wavelength - Reaches 100m over OM4 MMF or 70m over OM3 MMF using MTP/MPO-12 parallel optics interface - Digital Optical Monitoring (DOM) provides real-time access to transmit power, receive power, temperature, bias current, and supply voltage via I2C interface per QSFP28 MSA - Hot-swappable installation in QSFP28 MSA-compliant ports without interrupting host equipment operation - Supports breakout to 4x25GBASE-SR SFP28 interfaces for flexible rack-to-rack and top-of-rack connectivity

Features

• IEEE 802.3bm 100GBASE-SR4 standard compliance ensures full interoperability with multi-vendor QSFP28 host systems and eliminates vendor lock-in for parallel optics deployments
• Four-lane parallel architecture uses independent 850nm VCSEL transmitters and PIN photodetectors, each operating at 25.78125 Gbps with internal CDR for aggregate 100 Gbps full-duplex transmission
• 1.9 dB minimum optical link budget supports 100m transmission over OM4 fiber or 70m over OM3, accommodating typical data center spine-leaf distances with margin for connector and splice loss
• MTP/MPO-12 ribbon cable interface uses 8 active fibers (4 transmit, 4 receive) for single-connector deployment, reducing cable management complexity in high-density 100G environments
• Operates from single 3.3V supply with <3.5W power dissipation, lowering thermal load and per-port power costs compared to active copper alternatives at equivalent reach
• Hot-swappable in energized QSFP28 ports per MSA specification, allowing field replacement or port migration without service interruption or host reboot
• DDM parameters accessible via I2C conform to SFF-8636 management interface for integration with network monitoring systems and automated threshold alerting

FAQs

Q: Will this work in place of the Juniper JNP-QSFP-100G-SR4?
A: Yes. This transceiver is fully compatible with the JNP-QSFP-100G-SR4 specification. It conforms to the same IEEE 802.3bm 100GBASE-SR4 standard, uses the identical QSFP28 form factor, and delivers 100 Gbps operation at 850nm over multi-mode fiber. It is plug-and-play compatible with any Juniper platform that lists the JNP-QSFP-100G-SR4 as a supported optic.

Q: Which Juniper platforms support this transceiver?
A: This transceiver is compatible with any Juniper switch or router with QSFP28 ports that support 100GBASE-SR4 optics, as defined by the platform hardware compatibility tool. The requirement is a standards-compliant QSFP28 electrical interface supporting IEEE 802.3bm signaling at 25.78125 Gbps per lane. Consult your platform datasheet or the Juniper Hardware Compatibility Tool for confirmed support.

Q: What fiber type and patch cable do I need for 100m reach?
A: For 100m transmission you need OM4 multi-mode fiber with a 12-fiber MTP/MPO ribbon cable. OM3 fiber limits reach to 70m due to higher modal dispersion at 850nm. The cable must be Type B polarity (key-up to key-down) for proper transmit-to-receive lane mapping. Using OM4 with <3.0 dB/km attenuation at 850nm ensures the module's 1.9 dB link budget covers 100m plus typical connector insertion loss.

Q: Can I break out this transceiver to four separate 25G connections?
A: Yes. The four independent 25 Gbps optical lanes can be broken out to four separate 25GBASE-SR SFP28 ports using an MTP/MPO to 4x duplex LC breakout cable. Each lane operates autonomously at 25.78125 Gbps signaling rate. The host switch must support QSFP28 breakout mode configuration. Note that breakout reduces per-lane reach to 100m on OM4 or 70m on OM3, governed by 25GBASE-SR specifications.

Q: Does this transceiver require forward error correction (FEC) to be enabled?
A: FEC is not required for 100GBASE-SR4 operation at the physical layer, as the 1.9 dB optical link budget and CDR on each lane provide adequate margin for error-free transmission over specified distances. However, many switches enable RS-FEC by default on 100G ports for additional bit error rate improvement. The transceiver operates correctly with FEC enabled or disabled, controlled by host configuration. Verify both link ends use matching FEC settings.
