StarTech.com HPE J9151A Compatible SFP+ Module - 10GBASE-BX BiDi SMF Transceiver

This StarTech.com model is a purpose-built, high-performance SFP+ BiDi transceiver designed to work with HP J9151A hardware and the StarTech J9151A-BX-D-ST counterpart. The J9151A-BX-U-ST is engineered to deliver reliable 10GBASE-BX connectivity over single-mode fiber (SMF), enabling cost-effective uplink and downlink across long distances in enterprise, data-center, and campus networks. It’s a plug-and-play, vendor-friendly solution that aligns with 10GBASE-BX MSA specifications, ensuring smooth operation in mixed-vendor environments without sacrificing speed or integrity.

BiDi (bidirectional) technology uses two wavelengths on a single fiber strand to carry both directions of traffic, which means you can consolidate fiber cabling while preserving robust 10 Gbps performance. This upstream SFP+ transceiver is fully programmed and tested to work with compatible BX ports on switches and routers, delivering stable link negotiation, low insertion loss, and dependable error performance. With a maximum reach of up to 10 kilometers on standard single-mode fiber, it’s an ideal choice for campus backbones, data-center interconnects, and remote office deployments where fiber runs are lengthy but the network demands remain high.

• Broad compatibility and seamless integration: Engineered to be HP J9151A compatible and to pair with StarTech.com's J9151A-BX-D-ST, this SFP+ BX module is designed, programmed and tested to function across 10GBASE-BX compatible switches and routers. It provides a flexible, vendor-agnostic option that simplifies multi-vendor deployments without sacrificing performance.
• BiDi technology for efficient fiber usage: The BX BiDi design uses two wavelengths on a single SMF fiber, enabling separate transmit and receive paths while minimizing fiber plant requirements. This arrangement reduces cable clutter and costs while maintaining strong signal integrity for high-speed 10 Gbps links.
• Long-reach, high-performance networking: Capable of reaching up to 10 kilometers on single-mode fiber, this transceiver supports inter-building links, data-center uplinks, and remote-site connectivity with reliable performance. Link quality remains favorable under typical enterprise networking conditions, with careful fiber installation and proper patch cord selection.
• Easy, reliable deployment: As a hot-swappable SFP+ module, installation is straightforward: simply slide the module into a compatible SFP+ slot and secure it. No complex software changes or external power solutions are required. This makes it convenient for routine upgrades, replacements, or mixed-vendor network refresh cycles.
• MSA-compliant and future-ready: Built to the 10GBASE-BX MSA standard, the module ensures broad compatibility across BX-enabled devices and non-proprietary systems. The upstream/downstream ST connectors provide stable fiber connectivity in dense, high-traffic environments and support scalable, future-proof network designs.

How to Install StarTech.com HPE J9151A Compatible SFP+ Module

Step 1: Power down the switch or router (or disable the port if your device supports hot-swap) to protect sensitive electronics and minimize the risk of ESD during installation.

Step 2: Locate an available SFP+ slot and remove any existing module if required. Handle the module by its edges and avoid touching the connector surface.

Step 3: Align the StarTech J9151A BX SFP+ module with the slot and carefully insert it until it seats fully and the latch engages. Do not force the module; if it does not seat cleanly, remove and re-seat it.

Step 4: Connect the SMF fiber patch cables to the upstream and downstream ports as required by your network topology. Use clean, properly terminated ST connectors and ensure the fiber is routed without excessive bending to preserve signal integrity.

Step 5: Restore power to the device or re-enable the port. Check the link status LEDs on both the SFP+ module and the switch/router to confirm a 10G link is established. If available, run a quick throughput test to verify bandwidth and error rates.

Step 6: Document the installation, including fiber path, connector type, and device port mappings. Label cables where possible to facilitate future maintenance, upgrades, or relocations.

Frequently asked questions

• Q: What is 10GBASE-BX BiDi? A: 10GBASE-BX BiDi is a bidirectional, two-wavelength optical standard that allows two directions of data to share a single fiber strand. One wavelength carries the transmit signal, while the other carries the receive signal, reducing fiber count and simplifying cabling in 10 Gigabit networks.
• Q: Is this module compatible with HP J9151A devices? A: Yes. The J9151A-BX-U-ST is designed to be HP J9151A compatible and pairs with StarTech.com's J9151A-BX-D-ST for a consistent, reliable BX BiDi solution across compatible MSA switches and routers.
• Q: What distance can I reach with this transceiver? A: The module supports up to 10 kilometers on standard single-mode fiber, though actual reach can vary based on fiber quality, connectors, and installation conditions.
• Q: What connectors does this variant use? A: This BiDi module variant uses ST-style connectors for both upstream and downstream links, as indicated by the U-ST and D-ST model naming. Verify port compatibility on your equipment before purchase.
• Q: Is the module hot-swappable? A: Yes. SFP+ BX BiDi modules are designed to be hot-swappable in compatible network devices, enabling straightforward upgrades without powering down the entire system in many cases. Always follow your device’s hot-swap procedures.
