Questions & Answers
What is the HP-compatible 100BASE-BX10-D SFP Transceiver (SKU: JD491A-C)?
The HP-compatible 100BASE-BX10-D SFP Transceiver is a hot-pluggable, single-fiber, bi-directional module that delivers 100 Mbps Ethernet over up to 10 km on single-mode fiber.
Which wavelength does the 100BASE-BX10-D transceiver use?
The 100BASE-BX10-D uses dual-wavelength WDM technology: 1310 nm for transmit and 1550 nm for receive, enabling bidirectional data on a single fiber.
What cable type and distance supports the JD491A-C module?
This module supports single-mode fiber (SMF) with a maximum reach of 10 km over a single strand fiber using WDM.
Is the JD491A-C hot-pluggable?
Yes, the JD491A-C SFP Transceiver is hot-pluggable, allowing you to install or remove it without powering down your switch or router.
Which HP devices support this 100BASE-BX10-D SFP?
The transceiver is compatible with HP ProCurve, Aruba, and HPE switches and routers that feature a standard SFP port supporting 100BASE-BX10-D.
Is the JD491A-C compliant with industry standards?
Yes, it meets MSA (Multi-Source Agreement) standards, IEEE 802.3ah 100BASE-BX10-D, and RoHS environmental guidelines.
What are the operating temperature specifications?
Operating temperature ranges from 0 °C to 70 °C (32 °F to 158 °F), suitable for standard data-center and telecommunications environments.
How do I install the 100BASE-BX10-D SFP Transceiver?
Align the SFP module with the slot, slide it in until it clicks, then connect the single-mode fiber patch cable—no additional configuration is required.
Can I use the JD491A-C in a mixed-vendor network?
Yes, the module’s MSA compliance and IEEE standard support enable interoperability with other vendors’ 100BASE-BX10-D ports.
What are the power consumption specifications?
Typical power consumption is less than 1 W, ensuring energy efficiency and minimal heat dissipation in rack environments.
Does this transceiver support auto-negotiation?
Yes, it supports auto-negotiation for 100 Mbps full-duplex operation, simplifying network link establishment.
Can I extend beyond 10 km with this module?
No, the JD491A-C is designed for optimal performance up to 10 km; exceeding this distance may degrade signal integrity.

Ideal for enterprise LAN backbones, metro-Ethernet links, FTTH deployments, and any application requiring 100 Mbps over single-mode fiber.
Does HP support OEM-compatible transceivers?
While HP recommends original HP optics, many users reliably deploy OEM-compatible transceivers like JD491A-C without voiding switch warranties, provided firmware allows 3rd-party modules.
What warranty covers the JD491A-C SFP module?
The module typically includes a one-year limited warranty covering defects in materials and workmanship under normal use.
How can I verify link status after installation?
Check the SFP port LED on your switch or use CLI commands (e.g., show interfaces transceiver details) to confirm link up and optical parameters.
