Product information

Description

HP Enterprise JL251A-RFB is a 40G QSFP+ BiDi (single-lambda bidirectional) optical transceiver module engineered for short-reach fiber links. The module supports an aggregate 40 Gbps throughput over duplex multimode or single-mode fiber using a QSFP+ interface and single-wavelength bidirectional signaling. Designed for data center, aggregation and enterprise network environments, this transceiver helps increase port density and reduces cabling complexity by enabling bidirectional transmission on a single fiber pair.

Advantages

The JL251A-RFB transceiver delivers 40G connectivity in a QSFP+ form factor while using single-lambda bidirectional optics to reduce fiber count and simplify cabling. It provides compatibility with standard QSFP+ interfaces and is intended for short-reach applications, making it suitable where compact, high-density 40G links are required. The module's design supports integration into existing network equipment from HP Enterprise and other compatible systems that accept QSFP+ transceivers.

Suitable for

  • Data center uplinks and top-of-rack (ToR) switches requiring 40G short-reach connections
  • Enterprise aggregation links where reduced fiber cabling is desired
  • Network equipment with QSFP+ ports supporting single-lambda BiDi optics
  • Environments aiming to increase port density while maintaining 40G throughput

Key specifications

  • Brand: HP Enterprise
  • Manufacturer part number (MPN): JL251A-RFB
  • EAN: 5704174956815
  • Form factor: QSFP+
  • Data rate: 40 Gbps aggregate
  • Optical mode: Single-lambda bidirectional (BiDi)
  • Intended reach: Short-reach fiber links (multimode or single-mode)
  • Category: Network transceiver module

How to use

Install the JL251A-RFB into a compatible QSFP+ port on network equipment while the device is powered down or following the manufacturer's hot-swap guidance. Use appropriate single-lambda BiDi fiber patching that matches the module's transmit/receive wavelength arrangement and the connected port's requirements. Verify link status and port configuration on the switch or router software to ensure the transceiver is recognized and operating at 40 Gbps. Follow any vendor-specific compatibility and firmware recommendations to maintain proper operation.

Использование и рекомендации

For reliable performance, use certified fiber cabling and maintain proper optical cleanliness. Confirm compatibility with your switch or router model and consult HP Enterprise documentation for detailed installation and interoperability notes.
