Description

The JNP-SFP-10G-BX40U-BCC is a drop-in compatible replacement for the Juniper JNP-SFP-10G-BX40U. This BiDi SFP+ transceiver delivers plug-and-play 10 Gigabit Ethernet over a single strand of single-mode fibre, reducing fibre infrastructure requirements by 50% compared to duplex optics. - 10GBASE-BX40-U standard compliance guarantees interoperability with IEEE 802.3ae and SFP+ MSA specifications - SFP+ form factor with LC simplex connector, 1270nm TX / 1330nm RX wavelengths, up to 40km reach over OS2 single-mode fibre - Digital Diagnostic Monitoring (DDM) via SFF-8472 for real-time optical power, temperature, and bias current monitoring - Bidirectional transmission architecture: this upstream (U) module pairs with a downstream (D) counterpart transmitting 1330nm/receiving 1270nm - Hot-swappable installation in any standards-compliant SFP+ port with commercial operating temperature range (0 to 70°C) - Power consumption under 1.2W, suitable for metro access, enterprise campus, and regional network applications

Features

• IEEE 802.3ae 10GBASE-BX40-U compliance ensures full interoperability with any standards-compliant 10G BiDi link, eliminating vendor lock-in for single-fibre 10G deployments
• BiDi architecture uses WDM to separate TX (1270nm) and RX (1330nm) on one fibre strand, halving fibre plant requirements and enabling cost-effective metro reach extension
• SFF-8472 DDM provides real-time access to transmit/receive optical power, supply voltage, temperature, and laser bias current for proactive link health monitoring
• Must be deployed as a pair with a complementary BX40D module (1330nm TX / 1270nm RX) at the far end; asymmetric wavelengths prevent self-interference and define link direction
• Hot-swappable SFP+ form factor supports in-service insertion and removal without powering down the host platform, maintaining uptime during maintenance
• DFB laser and PIN photodetector design delivers low power consumption and stable optical output across the 0 to 70°C commercial temperature range
• Suitable for point-to-point 10G Ethernet links in enterprise campus, service provider access, CPRI fronthaul, and data centre interconnect applications requiring simplex fibre

FAQs

Q: Will this work in place of the Juniper JNP-SFP-10G-BX40U?
A: Yes. The JNP-SFP-10G-BX40U-BCC is built to the same SFP+ MSA and IEEE 802.3ae 10GBASE-BX40-U specifications as the original Juniper module. It delivers identical 10Gbps data rate, 1270nm TX / 1330nm RX operation, and 40km reach over single-mode fibre. This transceiver is plug-and-play in any Juniper platform with SFP+ ports and recognises the module for seamless network integration.

Q: Which Juniper platforms support this transceiver?
A: This transceiver is compatible with any Juniper switch or router featuring SFP+ ports that accept 10GBASE-BX optics, including EX series switches, QFX series data centre switches, MX series routers, and PTX series packet transport platforms. The host device must support BiDi (bidirectional) optics and recognise the 10GBASE-BX40-U standard. Verify your specific platform datasheet or hardware compatibility tool to confirm SFP+ BiDi support.

Q: Why does this module have different TX and RX wavelengths, and what does that mean for deployment?
A: BiDi optics use wavelength-division multiplexing (WDM) to transmit and receive on a single fibre strand. This upstream (U) variant transmits at 1270nm and receives at 1330nm. The far-end transceiver must be a downstream (D) variant (such as JNP-SFP-10G-BX40D) that transmits 1330nm and receives 1270nm. You cannot connect two upstream or two downstream modules together; the wavelength pairing defines link polarity and prevents signal collision.

Q: What fibre type and patch cable configuration does this require?
A: This module requires OS2 single-mode fibre with a simplex LC connector (single strand, not duplex). Standard single-mode patch cables rated for 1310nm and 1550nm transmission windows will support both the 1270nm and 1330nm wavelengths used by BiDi optics. Maximum reach of 40km assumes low-loss OS2 fibre, clean connectors, and adequate link budget; actual reach depends on total insertion loss and fibre attenuation.

Q: Can I monitor link performance and optical power levels with this transceiver?
A: Yes. This module implements SFF-8472 Digital Diagnostic Monitoring (DDM), also called Digital Optical Monitoring (DOM). You can read real-time TX and RX optical power (in dBm), supply voltage, temperature, and laser bias current via the I2C interface. Most network operating systems and management platforms display these parameters, allowing you to track link margin, detect fibre degradation, and troubleshoot connectivity issues before they cause outages.
