StarTech.com Juniper SFP-GE10KT13R15 Compatible SFP Module — 1000BASE-BX-U BiDi Fiber (SMF)

The StarTech.com Juniper SFP-GE10KT13R15 Compatible SFP Module is a high-performance, plug-and-play transceiver designed to elevate your network’s reliability and efficiency. Engineered to meet the stringent requirements of Juniper gear, this 1000BASE-BX-U BiDi SFP transceiver provides seamless single-fiber bidirectional communication over standard single-mode fiber (SMF). It’s the perfect choice for data centers, campuses, and enterprise networks where space is at a premium and uptime is non-negotiable. With its robust build, precision optics, and industry-standard compatibility, it delivers a fast, stable link for Gigabit Ethernet uplinks and inter-switch connections while minimizing rack space and cabling complexity.

• Perfect Juniper compatibility for reliable links: This SFP module is designed to align with Juniper networking equipment, ensuring smooth interoperability with Juniper EX, MX, SRX, and other compatible devices. It’s a trusted choice for network engineers who require dependable performance in mixed-vendor environments while preserving your existing investments.
• 1 Gbps BiDi fiber over SMF: Built for 1000BASE-BX-U operation, this transceiver enables full-duplex Gigabit Ethernet over a single optical fiber using bidirectional transmission. The BiDi design reduces fiber counts and simplifies fiber management without sacrificing link quality, making it ideal for space-constrained deployments.
• Wavelengths engineered for long-distance links: The module employs Tx at 1310 nm and Rx at 1550 nm, a common BiDi configuration for single-fiber, long-reach links. This wavelength pairing helps minimize dispersion effects over SMF, supporting stable performance across typical enterprise and data-center distances.
• Single-mode fiber (SMF) with LC connectors: Optimized for SMF cabling, the transceiver uses standard LC duplex connectors. Pair it with compatible LC-LC BiDi patch cords for a clean, low-loss installation that preserves signal integrity and reduces connector-based attenuation over distance.
• Simple, hot-swappable installation and scalability: As an SFP transceiver, it drops into any standard SFP port without requiring software changes or firmware updates. This makes upgrades or expansions fast, non-disruptive, and scalable as your network grows, while preserving downtime and maintenance windows.

how to install StarTech.com Juniper SFP-GE10KT13R15 Compatible SFP Module

• Power down or safely suspend traffic on the switch or router port where you will install the SFP module, following your vendor’s standard procedures for maintenance and electronics handling.
• Open the switch or router SFP slot cover and insert the SFP-GE10KT13R15 module with the module’s label facing up and the connector aligned for a straight, secure seating. Gently push until you hear a click indicating a firm connection.
• Connect a single-fiber BiDi SMF patch cord with LC connectors to the transceiver’s fiber side, ensuring the Tx and Rx ends are properly oriented according to your network design. Use the same patch cords at both ends if linking two devices, following the BiDi link guidance (i.e., Tx to Rx on the opposite end).
• Power up the device and observe the link status. The SFP may perform a brief calibration as the port negotiates; once the port shows a solid link, you can begin testing throughput and monitoring port health.
• Validate network performance with standard tests (ping, throughput tests, and monitoring tools). If you experience any link instability, verify fiber cleanliness, connector seating, polarity, and that the fiber is SMF rated for the chosen distance. Avoid bending fibers beyond recommended radii and replace any damaged cables.

Frequently asked questions

• What devices is this SFP module compatible with? The module is designed to work with Juniper network devices and is compatible with StarTech.com’s range of compatible SFP ports. Ensure your equipment supports 1000BASE-BX-U BiDi transceivers and single-fiber BiDi configurations before installation.
• What is the data rate and what speeds can I expect? This transceiver provides 1 Gbps Ethernet via 1000BASE-BX-U. It is intended for Gigabit Ethernet uplinks and inter-switch connections over single-mode fiber using bidirectional signaling.
• What kind of fiber should I use? Use single-mode fiber (SMF) with LC duplex connectors. The BiDi approach uses a single fiber strand for two directions, so correct pairing of Tx/Rx wavelengths and proper polarity is essential for optimal performance.
• What distance can I achieve with this module? Distances up to approximately 10 km are supported on SMF, depending on fiber quality, connectors, and environmental conditions. Longer runs may be possible with higher-quality fiber and proper installation, but verify your link budget first.
• Do I need special software or drivers to use this module? In most cases, SFP modules are hot-swappable and require no special software changes. The port negotiation occurs automatically, but always confirm compatibility with your switch/router model and firmware version.
• What warranty or support is available? StarTech.com provides standard product support and warranty terms for its components. Check the product page or contact StarTech support for the exact warranty duration and service options applicable to your region.
