SFP-10G-ER-I-BCC | Cisco Compatible 10GB Single-Mode ER - 40km (10GBASE-ER) Rugged / Industrial

Q: Will this work in place of the Cisco SFP-10G-ER-I?
A: Yes. The SFP-10G-ER-I-BCC is a drop-in replacement for the Cisco SFP-10G-ER-I. It matches the SFP+ form factor, 10.3125 Gbps data rate, 1550nm wavelength, 40km single-mode reach, and industrial temperature rating. It is fully compliant with IEEE 802.3ae 10GBASE-ER and operates plug-and-play in Cisco SFP+ ports that support the original module.

Q: Which Cisco platforms support this module?
A: This module is compatible with Cisco switches, routers, and other networking equipment featuring SFP+ ports that support 10GBASE-ER optics and industrial-rated transceivers. Specific platform compatibility depends on the chassis SFP+ slot specifications and software support for industrial temperature modules. Consult the Cisco 10 Gigabit Ethernet Transceiver Modules Compatibility Matrix for detailed platform and software version requirements.

Q: What fibre type is required for 40km transmission?
A: This module requires standard single-mode fibre conforming to ITU-T G.652 specification (OS1 or OS2). Multimode fibre is not compatible. Achieving the full 40km reach depends on total link loss budget, including fibre attenuation, splice loss, and connector loss. For links shorter than 40km, an inline optical attenuator may be required to prevent receiver overload due to the module's high transmit power at 1550nm.

Q: Can this module operate at both commercial and industrial temperatures?
A: Yes. The industrial temperature range of -40°C to 85°C encompasses the commercial range (0°C to 70°C), so the module operates across both environments. It is designed for cold-start capability at -40°C, meaning the transceiver can initialise in extreme cold conditions. This makes it suitable for deployments where temperature varies widely, such as outdoor enclosures, remote cell sites, or seasonal climate extremes.

Q: Does the 1550nm wavelength affect link budget planning compared to 1310nm optics?
A: Yes. The 1550nm wavelength experiences lower attenuation on G.652 single-mode fibre compared to 1310nm (approximately 0.2 dB/km versus 0.35 dB/km), which is why this module achieves 40km reach. However, chromatic dispersion is higher at 1550nm. Link budget planning must account for both fibre loss and dispersion penalty, especially on longer spans or where fibre quality varies. The module provides sufficient optical budget to tolerate real-world losses within the 40km design limit.
