Description

The QSFP-100G-LR4-BCC is a drop-in compatible replacement for the Arista QSFP-100G-LR4. This QSFP28 transceiver provides plug-and-play compatibility with Arista switches and routers requiring 100GBASE-LR4 connectivity. - Compliant with IEEE 802.3ba 100GBASE-LR4 and QSFP28 MSA standards, guaranteeing interoperability with standards-compliant network equipment - QSFP28 form factor delivering 100Gbps over single-mode fibre using four LAN-WDM wavelengths at 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm - Supports transmission distances up to 10km over G.652 single-mode fibre with duplex LC connectors - Digital Diagnostic Monitoring support for real-time access to optical power, temperature, bias current, and supply voltage parameters - Four-lane architecture with 25.78Gbps per lane using LAN-WDM multiplexing and demultiplexing integrated within the module - Hot-swappable design allows installation and removal without interrupting host equipment operation

Features

• IEEE 802.3ba 100GBASE-LR4 compliance ensures optical interoperability with any standards-compliant 100G LR4 transceiver up to 10km
• Four-lane LAN-WDM architecture multiplexes 4x 25.78Gbps electrical lanes onto four distinct optical wavelengths, then combines them into a single duplex fibre pair using integrated MUX/DEMUX
• Does not require Forward Error Correction for full 10km reach over G.652 single-mode fibre, simplifying deployment in environments where FEC is unavailable or undesirable
• Cooled LAN-WDM EA-DFB laser transmitters and high-sensitivity PIN photodiode receivers deliver the optical budget required for 10km links with margin for patch panel loss
• Digital diagnostics accessible via I2C interface per QSFP28 MSA specification, enabling network management systems to monitor module health without service interruption
• Hot-swappable QSFP28 form factor supports field installation into any QSFP28 MSA-compliant port without powering down the host switch or router
• Commercial temperature range operation from 0 to 70°C suits standard data centre and enterprise network environments

FAQs

Q: Will this work in place of the Arista QSFP-100G-LR4?
A: Yes. This module is plug-and-play compatible with the Arista QSFP-100G-LR4. It adheres to the same IEEE 802.3ba 100GBASE-LR4 standard, uses the same QSFP28 form factor, delivers the same 103.125 Gbps data rate over four 25.78 Gbps lanes, and operates at the same LAN-WDM wavelengths. It will function identically in any Arista platform with QSFP28 ports.

Q: Which Arista platforms support this transceiver?
A: This module works in any Arista switch or router with QSFP28 ports that support 100GBASE-LR4 optics. If your Arista platform lists the QSFP-100G-LR4 as a supported optic, this transceiver will operate in that port. Verify your platform documentation for 100G QSFP28 compatibility.

Q: What are the four LAN-WDM wavelengths and why does this matter?
A: This module transmits on four distinct wavelengths defined by IEEE 802.3ba: 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm. These wavelengths are multiplexed into a single duplex fibre pair, allowing 100Gbps transmission over just two fibres instead of eight. The integrated MUX/DEMUX manages wavelength separation, so you connect it like any duplex transceiver. This approach is what enables the 10km reach.

Q: Does this transceiver require FEC to reach 10km?
A: No. IEEE 100GBASE-LR4 does not employ FEC. This module delivers the full 10km reach over G.652 single-mode fibre without requiring Forward Error Correction on the host platform. If your switch supports FEC and has it enabled, the module will still operate, but FEC is not necessary to achieve the 10km specification.

Q: Can I use this with OM3 or OM4 multimode fibre?
A: No. This is a single-mode transceiver designed exclusively for OS2/G.652 single-mode fibre. The LAN-WDM wavelengths at 1295-1310nm and the receiver sensitivity are optimised for single-mode transmission. Attempting to use multimode fibre will result in no link or severely degraded performance. For multimode applications, use a 100GBASE-SR4 transceiver instead.
