Description

The QSFP-40G-SR4-Arista-BCC is a drop-in compatible replacement for the Arista QSFP-40G-SR4-ARISTA. It provides plug-and-play 40 Gigabit Ethernet connectivity in Arista QSFP+ ports without configuration changes. - IEEE 802.3ba 40GBASE-SR4 and QSFP+ MSA compliance ensures interoperability with standard SR4 interfaces - QSFP+ form factor with MPO-12 connector, 850nm wavelength, 100m reach over OM3 or 150m over OM4 multi-mode fibre - Four parallel 10Gbps lanes with VCSEL transmitter technology for 40Gbps aggregate throughput - Digital optical monitoring support via I2C interface provides real-time access to operating parameters - Hot-swappable design enables installation and replacement without network interruption - Compatible with MTP-12 parallel fibre infrastructure using 8 of 12 fibres per IEEE standard lane mapping

Features

• IEEE 802.3ba 40GBASE-SR4 compliance guarantees electrical and optical interoperability with any standards-compliant 40G SR4 interface, regardless of vendor
• Four independent 10Gbps transmit and receive channels multiplexed within the module, each using VCSEL technology at 850nm nominal wavelength
• MPO-12 connector uses only 8 of 12 available fibres per IEEE lane mapping (strands 1 to 4 and 9 to 12), allowing cost-optimised cable assemblies
• I2C interface exposes DOM parameters including optical power, temperature, bias current, and supply voltage for SNMP integration and link diagnostics
• Power consumption under 1.5W typical enables high-density 40G deployments without exceeding chassis thermal budgets
• Hot-swappable QSFP+ MSA form factor allows field installation and removal while adjacent ports remain operational

FAQs

Q: Will this work in place of the Arista QSFP-40G-SR4-ARISTA?
A: Yes. This module is designed as a plug-and-play replacement. It conforms to the same IEEE 802.3ba 40GBASE-SR4 standard, uses the identical QSFP+ form factor, operates at 850nm over multi-mode fibre, and supports the same 100m OM3 or 150m OM4 reach as the Arista original.

Q: Which Arista platforms support this transceiver?
A: This module works in any Arista switch with QSFP+ ports that support 40GBASE-SR4 optics. The IEEE 802.3ba compliance and QSFP+ MSA form factor ensure compatibility across Arista platforms. Confirm your specific platform supports 40G SR4 optics via Arista documentation.

Q: What fibre type and polarity does the MPO-12 connector require?
A: The module requires OM3 or OM4 multi-mode fibre with MPO-12 connectors. IEEE 40GBASE-SR4 specifies that only 8 of the 12 fibres are used, with transmit on strands 1 to 4 and receive on 9 to 12. Use standard polarity Type B MPO cables for switch-to-switch connections, or verify polarity requirements if using breakout cassettes.

Q: Does this module support 4x10G breakout mode?
A: The optical interface supports four independent 10Gbps lanes, which is the physical basis for breakout operation. However, breakout functionality depends on the host switch supporting 4x10G mode in both hardware and software. Consult your Arista platform documentation to confirm 4x10G capability and the required CLI configuration.

Q: How does reach differ between OM3 and OM4 fibre for this module?
A: OM3 fibre supports up to 100m, while OM4 extends reach to 150m at 850nm. The difference arises from OM4's lower modal bandwidth attenuation and tighter manufacturing tolerances. Both assume an optical power budget within the 1.9dB minimum guaranteed by IEEE 40GBASE-SR4, including connector insertion loss and fibre attenuation.
