Description

The QFX-QSFP-40G-SR4-BCC is a drop-in compatible replacement for the Juniper QFX-QSFP-40G-SR4. It delivers 40 Gigabit Ethernet connectivity over multi-mode fibre and works plug-and-play in Juniper platforms with QSFP+ ports. - IEEE 802.3ba 40GBASE-SR4 compliance guarantees interoperability with any standard 40GBASE-SR4 interface - QSFP+ form factor with MPO connector, 850nm wavelength, 100m reach on OM3 or 150m on OM4 multi-mode fibre - Four independent 10Gbps lanes using VCSEL array technology, aggregating to 40Gbps full-duplex bandwidth - Digital diagnostics monitoring (DDM) via SFF-8436 compliant I2C interface for real-time optical parameters - Hot-swappable design with maximum power dissipation under 1.5W - Operating temperature range 0 to 70 degrees C, suitable for data centre and enterprise environments

Features

• IEEE 802.3ba 40GBASE-SR4 standard ensures native interoperability with any compliant 40G interface and enables 4x10G breakout to 10GBASE-SR ports using parallel-to-duplex breakout cables
• Four independent full-duplex optical channels, each operating at 10.3Gbps over parallel ribbon cable with MPO connector for 40Gbps aggregate throughput
• VCSEL transmitter array at 850nm paired with PIN photodiode receiver array and integrated TIA for reliable short-reach multi-mode transmission
• SFF-8436 compliant digital diagnostics provide real-time access to transmit/receive optical power, temperature, bias current, and supply voltage via I2C interface
• Hot-swappable with low power draw under 1.5W from single 3.3V supply, suitable for high-density 40G switch and router deployments
• 12-fibre MPO receptacle with guide pin alignment supports OM3 fibre to 100m and OM4 fibre to 150m, each lane compliant with 10GBASE-SR electrical and optical specifications
• Designed to operate 0 to 70 degrees C with global control signals including ModSelL, ResetL, and LPMode for flexible multi-module management on shared I2C bus

FAQs

Q: Will this work in place of the Juniper QFX-QSFP-40G-SR4?
A: Yes. This transceiver matches the QFX-QSFP-40G-SR4 in form factor, data rate, wavelength, and reach. It is compliant with IEEE 802.3ba 40GBASE-SR4 and the QSFP+ MSA, ensuring plug-and-play compatibility with any Juniper platform that supports the original part number.

Q: Which Juniper platforms support this transceiver?
A: This module works in any Juniper platform with QSFP+ 40G ports running Junos OS or Junos OS Evolved that supports 40GBASE-SR4 interfaces. Confirmed compatible platform families include QFX Series switches, EX Series switches, ACX routers, MX routers, and PTX packet transport platforms, subject to the minimum software release for each model.

Q: What are the fibre requirements for 100m versus 150m reach?
A: For 100m reach, use OM3 laser-optimised 50/125 micron multi-mode fibre. For 150m reach, use OM4 laser-optimised 50/125 micron multi-mode fibre. Both require 12-fibre MPO ribbon cable terminated with MPO female connectors. Actual reach depends on fibre quality, connector loss, and link budget conditions.

Q: Can this transceiver be used in 4x10G breakout mode?
A: Yes. Each of the four lanes is compliant with IEEE 10GBASE-SR specifications. Using a 12-fibre parallel-to-duplex breakout cable, this module can connect to four separate 10GBASE-SR interfaces, with each lane supporting up to 100m on OM3 or 150m on OM4 fibre, subject to platform support for breakout configuration.

Q: What diagnostic parameters are available via DDM?
A: The SFF-8436 compliant DDM interface provides real-time monitoring of transmit optical power, receive optical power, module temperature, transmit bias current, and supply voltage for each lane. These parameters are accessible via the two-wire serial interface and can be displayed in the platform CLI or network management system.
