The SFP-10G-BX40U-I-C is a Cisco-compatible 10GBASE-BX40-U SFP+ bidirectional transceiver designed for single-mode fiber links up to 40 km.
Yes, the SFP-10G-BX40U-I-C is fully compatible with Cisco switches and routers that support 10GBASE-BX SFP+ form-factor modules.
This module supports optical links of up to 40 km on single-mode fiber (SMF) using a bidirectional WDM design.
It operates with a Tx wavelength of 1271 nm and an Rx wavelength of 1331 nm for bidirectional transmission over a single fiber.
The module uses single-mode fiber (SMF) with an LC duplex connector for installation.
Yes, it includes DDM (also known as DOM) functionality to monitor optical power, temperature, bias current and supply voltage.
Absolutely. The SFP-10G-BX40U-I-C adheres to the SFP+ Multi-Source Agreement (MSA) for guaranteed interoperability.
It supports a fixed data rate of 10.3125 Gbps for 10G Ethernet applications.
The module operates reliably between 0 °C to 70 °C (standard commercial temperature range).
Its typical power consumption is 1 W, maximizing energy efficiency for 10G networks.
No, the SFP-10G-BX40U-I-C is designed for bidirectional WDM over a single fiber but is not certified for CWDM/DWDM channel grids.
It’s ideal for metro, access aggregation, campus backbone and data-center interconnects requiring 40 km 10G links.
Insert the module into any empty SFP+ slot until it clicks, then connect LC-terminated single-mode fiber; the device will auto-detect the transceiver.
No manual configuration is required; the switch recognizes the module automatically and sets the link parameters.
It is backed by a one-year manufacturer warranty covering defects in materials and workmanship under normal use.
Use your switch’s show interface transceiver command or network management tool to view link state, optical power levels and diagnostics.
