Description

The JNP-SFP-10G-BX40D-BCC is a drop-in compatible replacement for the Juniper JNP-SFP-10G-BX40D. This BiDi SFP+ transceiver provides plug-and-play compatibility with Juniper equipment featuring 10G SFP+ ports. - MSA compliant SFP+ BiDi transceiver designed for IEEE 802.3ae 10GBASE-BX applications, ensuring interoperability with standards-compliant equipment - Transmits at 1330nm and receives at 1270nm over a single strand of OS2 single-mode fibre via simplex LC connector, up to 40km reach - WDM technology enables bidirectional 10Gbps transmission on one fibre strand, doubling capacity without additional cabling infrastructure - Digital Diagnostics Monitoring (DDM) support for real-time access to optical power, temperature, bias current, and voltage parameters - Hot-swappable design with DFB laser transmitter and PIN receiver, suitable for 10G Ethernet and data centre applications - Must be deployed in matched pairs with complementary wavelength module (1270nm-TX/1330nm-RX) for bidirectional communication

Features

• IEEE 802.3ae 10GBASE-BX compliance guarantees interoperability with standards-based 10G Ethernet equipment and ensures reliable optical layer performance across mixed-vendor environments
• BiDi architecture uses WDM wavelength separation (1330nm TX / 1270nm RX) to achieve full-duplex 10Gbps communication over a single fibre strand, cutting fibre infrastructure requirements in half compared to duplex SFP+ modules
• DFB laser transmitter paired with PIN receiver delivers stable optical signal integrity across the full 40km span, with transmit power range of +1 to +5 dBm and receiver sensitivity better than -15 dBm
• SFF-8472 compliant digital diagnostics provide in-band monitoring of transmit/receive optical power, module temperature, laser bias current, and supply voltage for proactive link health assessment
• Simplex LC interface reduces port density requirements and simplifies patch panel layout in high-density deployments where fibre count is constrained
• Hot-swappable SFP+ form factor with low power consumption (typically under 1.2W) supports deployment in any MSA-compliant 10G SFP+ cage without service interruption
• Requires deployment in matched pairs with complementary wavelength partner (JNP-SFP-10G-BX40U or equivalent 1270nm-TX/1330nm-RX module) to complete the bidirectional optical path

FAQs

Q: Will this work in place of the Juniper JNP-SFP-10G-BX40D?
A: Yes. This module is designed as a direct replacement for the JNP-SFP-10G-BX40D. It matches the original specification: SFP+ form factor, 10Gbps data rate, 1330nm transmit / 1270nm receive wavelengths, 40km reach over single-mode fibre, and IEEE 802.3ae 10GBASE-BX compliance. The module is plug-and-play compatible and will initialize correctly in Juniper equipment with 10G SFP+ ports.

Q: Which Juniper platforms support this transceiver?
A: This transceiver is compatible with Juniper switches, routers, and appliances featuring 10G SFP+ ports that support BiDi optics. The platform must accept MSA-compliant SFP+ modules and support the 10GBASE-BX standard. Consult your platform documentation or Juniper HCT to confirm BiDi support for your specific model and software release.

Q: Why must this module be used in pairs, and what happens if wavelengths are mismatched?
A: BiDi transceivers use WDM to separate transmit and receive channels on the same fibre. This module transmits at 1330nm and receives at 1270nm. Its partner must do the opposite: transmit at 1270nm and receive at 1330nm. If both ends transmit on the same wavelength, the link will not establish because neither receiver will see its expected wavelength. The pair must have complementary wavelengths to form a working bidirectional path.

Q: Can I use this module for distances shorter than 40km without damaging the receiver?
A: Yes, but fibre spans significantly shorter than the rated distance may cause receiver overload due to excessive optical power. For links under approximately 5km, consider adding an in-line LC fibre attenuator (5dB or greater) to reduce received power and protect the PIN receiver from saturation. Monitor DDM receive power levels to confirm the signal remains within the specified operating range.

Q: What fibre type and quality is required to achieve the full 40km reach?
A: This transceiver is designed for OS2 single-mode fibre (G.652 compliant). Achieving 40km reach depends on total link budget, including fibre attenuation, splice loss, connector loss, and any inline components. OS2 fibre has maximum attenuation of 0.4 dB/km at 1310nm and 1550nm. Verify your installed fibre loss is within the module's power budget (typically 18 to 20 dB for this class). Dirty or damaged connectors will reduce usable span.
