Description

The GLC-BX40-U-I-BCC is a drop-in compatible replacement for the Cisco GLC-BX40-U-I. This industrial-temperature BiDi SFP transceiver operates plug-and-play in Cisco platforms requiring a 1000BASE-BX40-U upstream module. - IEEE 802.3z 1000BASE-BX40-U compliance guarantees interoperability with matching downstream modules on single-strand single-mode fibre - SFP form factor, 1.25Gbps data rate, 1310nm transmit / 1550nm receive wavelength pairing, simplex LC connector, up to 40km reach over 9/125µm SMF - Digital optical monitoring (DOM) per SFF-8472 provides real-time access to optical power, temperature, laser bias current, and supply voltage parameters - Industrial operating temperature range from -40°C to +85°C supports deployment in harsh environmental conditions - BiDi architecture uses integrated WDM diplexer to transmit and receive on a single fibre strand, reducing fibre infrastructure requirements by half - Hot-swappable installation enables field deployment and replacement without network interruption

Features

• IEEE 802.3z compliance ensures standards-based interoperability with any 1000BASE-BX downstream module transmitting at complementary wavelengths (1550nm TX / 1310nm RX)
• BiDi diplexer technology splits transmitted and received wavelengths on a single fibre strand, eliminating the need for duplex cabling in point-to-point links
• SFF-8472 DOM access enables network operators to monitor real-time optical output power, receive sensitivity, module temperature, laser bias current, and supply voltage without external test equipment
• Industrial temperature rating supports case temperatures from -40°C to +85°C, suitable for outdoor enclosures, industrial Ethernet switches, and rugged edge deployments
• 1310nm DFB laser transmitter paired with 1550nm InGaAs PIN receiver delivers 22dB minimum optical budget, sufficient for 40km over standard G.652 single-mode fibre under typical conditions
• Hot-pluggable SFP footprint with single 3.3V power supply enables field installation and module swaps without powering down host equipment
• Low EMI metal enclosure and RoHS-compliant design meet environmental and safety standards for commercial and industrial network infrastructure

FAQs

Q: Will this work in place of the Cisco GLC-BX40-U-I?
A: Yes. The GLC-BX40-U-I-BCC is a plug-and-play replacement that matches the Cisco GLC-BX40-U-I in form factor (SFP), data rate (1.25Gbps), standard (1000BASE-BX40-U), wavelength pairing (1310nm TX / 1550nm RX), reach (40km), and industrial temperature rating (-40°C to +85°C). It will initialise and operate identically in any Cisco platform with a compatible SFP slot.

Q: Which Cisco platforms support this industrial BiDi SFP?
A: This module is compatible with Cisco industrial Ethernet switches, routers, and media converters that support SFP ports and operate within the industrial temperature range. It works in any Cisco device with an MSA-compliant SFP slot that accepts 1000BASE-BX modules. Verify your platform supports BiDi upstream modules and industrial temperature operation if deploying in harsh environments.

Q: Why does this module require a matching downstream transceiver?
A: BiDi transceivers transmit and receive on different wavelengths over a single fibre strand. This upstream (U) module transmits at 1310nm and receives at 1550nm. It must connect to a downstream (D) module that transmits at 1550nm and receives at 1310nm (such as the GLC-BX40-D-I). The integrated WDM diplexer in each module splits the wavelengths, enabling bidirectional communication. Two upstream modules cannot communicate with each other.

Q: What fibre type and distance limitations apply to the 40km reach specification?
A: The 40km maximum reach applies to standard ITU-T G.652 single-mode fibre (9/125µm SMF) under typical conditions with a 22dB minimum optical budget. Actual distance depends on fibre attenuation, splice loss, connector loss, and any inline components. For links shorter than 10km, an optical attenuator may be required to prevent receiver saturation. OM3 and OM4 multimode fibres are not supported.

Q: Does this industrial-rated module support the same DOM parameters as commercial-temperature SFPs?
A: Yes. DOM functionality per SFF-8472 is fully supported across the entire industrial temperature range (-40°C to +85°C). You can monitor transmit optical power, receive optical power, module temperature, laser bias current, and supply voltage in real time via compatible network operating systems or management platforms. All parameters remain accurate and accessible even at temperature extremes.
