Description

The FN-TRAN-QSFP+ER-BCC is a drop-in compatible replacement for the Fortinet FN-TRAN-QSFP+ER. This transceiver provides plug-and-play 40 Gigabit Ethernet connectivity in Fortinet switches and routers with QSFP+ ports. - IEEE 802.3ba 40GBASE-ER4 compliance guarantees interoperability with standard 40G Ethernet equipment - QSFP+ form factor, 40km reach over single-mode fibre, duplex LC connector, 1271/1291/1311/1331nm CWDM wavelengths - Digital Optical Monitoring (DOM) support for real-time tracking of optical power, temperature, bias current, and voltage - Four-lane CWDM architecture multiplexes 4x10Gbps electrical lanes onto a single fibre pair for extended reach - Supports OTU3 (43.01Gbps) and STM-256 (39.81Gbps) applications in addition to 40G Ethernet - Operating temperature range 0 to 70 degrees Celsius for standard commercial environments

Features

• IEEE 802.3ba and 802.3bm compliance ensures the transceiver operates as a standards-compliant 40GBASE-ER4 interface, guaranteeing interoperability with any 40G Ethernet port that conforms to the same specification
• Four independent 10Gbps electrical lanes are converted to four CWDM optical wavelengths (1271, 1291, 1311, 1331nm), multiplexed onto a duplex fibre pair, and demultiplexed at the receiver, enabling full 40Gbps throughput over a single SMF connection
• DFB laser transmitters and APD photodiode receivers deliver the sensitivity required for 40km reach with a 19dB optical budget, suitable for metro networks and inter-site data centre links
• DOM functionality exposes per-lane optical power levels, module temperature, laser bias current, and supply voltage via I2C interface as defined by QSFP+ MSA, enabling proactive link monitoring and fault isolation
• Hot-swappable design allows installation and removal without powering down the host system, simplifying maintenance and reducing downtime in production networks
• Multi-protocol capable chipset supports 40G Ethernet (41.25Gbps), OTU3 (43.01Gbps), OTU3e2 (44.58Gbps), and STM-256 (39.81Gbps) signalling, though actual support depends on host port configuration
• Duplex LC connector simplifies fibre infrastructure compared to parallel optics (MPO/MTP) solutions, requiring only two fibres instead of eight or twelve

FAQs

Q: Will this work in place of the Fortinet FN-TRAN-QSFP+ER?
A: Yes. The FN-TRAN-QSFP+ER-BCC is a direct replacement for the Fortinet FN-TRAN-QSFP+ER. It meets the same IEEE 802.3ba 40GBASE-ER4 standard, uses the same QSFP+ form factor, operates at the same data rate (40Gbps), and delivers the same 40km reach over single-mode fibre. It is plug-and-play compatible with Fortinet equipment that lists the FN-TRAN-QSFP+ER as a supported transceiver.

Q: Which Fortinet platforms support this transceiver?
A: This transceiver works in any Fortinet device with QSFP+ or QSFP28 slots that support 40G operation. The official Fortinet transceiver datasheet indicates compatibility with systems that have QSFP+ ports. Verify your specific model supports 40GBASE-ER4 by checking the platform datasheet or compatibility matrix for QSFP+ transceiver support.

Q: What fibre type and grade are required for 40km reach?
A: You need single-mode fibre, typically OS2 grade (G.652 compliant). The transceiver has a minimum 19dB optical budget. To reach the full 40km, ensure your fibre plant has low enough attenuation (typically under 0.4dB/km for OS2) and account for connector losses and splice losses in your link budget. OM3 or OM4 multi-mode fibre is not supported for this transceiver.

Q: How does the four-lane CWDM architecture affect interoperability?
A: The transceiver splits 40Gbps into four parallel 10Gbps lanes and assigns each lane a distinct CWDM wavelength (1271, 1291, 1311, 1331nm). An internal MUX/DEMUX combines and separates these wavelengths. Both ends of the link must use 40GBASE-ER4 transceivers with matching CWDM lane assignments. Mixing with 40GBASE-LR4 or other 40G optics types will not work, as the wavelength plan differs.

Q: Can this transceiver operate over shorter distances, or is there a minimum reach?
A: Yes, it can operate over shorter distances than 40km. The 40km figure is the maximum rated reach. There is no enforced minimum distance for 40GBASE-ER4, though the high transmit power may require attenuators on very short links (under 2km) to avoid saturating the receiver. For distances under 10km, a 40GBASE-LR4 transceiver is typically more cost-effective.
