HPE JL745A 1G SFP LC SX 500m Multimode Fiber Transceiver

Overview

The HPE JL745A is a 1 Gigabit SFP transceiver designed for multimode fiber runs up to 500 meters using an LC connector and short-wavelength (SX/850nm) optics. It is TAA (Trade Agreements Act) compliant, making it a straightforward fit for U.S. federal agency deployments and government-contract infrastructure where domestic-sourcing documentation is a procurement requirement. If you are extending an Aruba network switch uplink across a campus backbone or connecting two IDF closets through existing multimode fiber plant, this module slots directly into any standard SFP cage.

Key Features

• 1 Gigabit SFP Form Factor: Drops into any SFP-compliant port on HPE Aruba switches and most third-party gear without requiring a media converter — one less device to power and manage in the rack.
• 500m Reach over Multimode Fiber: Covers intra-building and short campus hops cleanly. If your fiber run is under 500m of OM1, OM2, OM3, or OM4 multimode, this reach rating gives you headroom without stepping up to a more expensive single-mode module.
• LC Duplex Connector: LC is the dominant connector in modern multimode fiber infrastructure. No adapter needed if your patch panels and wall plates were installed in the last 15 years — plug-and-play with standard LC duplex jumpers.
• SX (850nm) Optics: Short-wavelength optics are cost-effective for multimode runs. The 850nm wavelength is the standard for 1G MMF links and is supported by the widest range of compatible fiber patch cables and media in the field.
• TAA Compliance: Meets Trade Agreements Act requirements, supporting GSA Schedule procurement and federal IT contracts that mandate TAA-compliant sourcing. Verify your specific contract vehicle for documentation requirements before ordering.

Integration and Compatibility

The JL745A is designed for HPE Aruba switching platforms that accept standard SFP transceivers, including the Aruba 2530, 2540, 2930, 5400R, and CX series. It is also broadly compatible with third-party switches that support standard 1G SFP interfaces, though always confirm interoperability with your specific switch firmware and vendor support policy before deploying at scale. Pair it with standard OM1/OM2/OM3/OM4 multimode fiber patch cables terminated with LC duplex connectors. For longer campus runs or single-mode fiber plants, consider an LX variant rated for single-mode distances instead.

Frequently Asked Questions

Q: Is the JL745A TAA compliant?

A: Yes. The JL745A carries TAA (Trade Agreements Act) compliance, supporting federal and government-contract procurement vehicles that require it.

Q: What fiber type does the JL745A require?

A: The JL745A is designed for multimode fiber (MMF) with an LC duplex connector. It is not intended for single-mode fiber runs.

Q: What is the maximum reach of the JL745A?

A: 500 meters over multimode fiber under standard 1G SX (850nm) operating conditions.

Q: What connector type does the JL745A use?

A: LC duplex — the standard connector for modern multimode fiber infrastructure.

Q: Will the JL745A work in non-HPE switches?

A: It is designed for HPE Aruba platforms. Compatibility with third-party switches depends on that vendor's SFP interoperability policy and firmware. Confirm with your switch vendor before deploying in non-HPE equipment.

Eden Phillips

The JL745A is a purpose-built 1G SFP module for multimode fiber links up to 500 meters — the spec that matters most when you are connecting two closets or buildings across existing MMF plant rather than pulling new single-mode. If your fiber infrastructure is already LC-terminated OM1 through OM4, this module installs without any additional adapters or converters.

Technical Highlights:

• 500m MMF Reach: Sufficient for most intra-campus IDF-to-MDF links. If your run is shorter than 500m and you are on multimode, this is the cost-effective choice versus a single-mode LX module, which is overkill for that distance.
• SX 850nm Optics: The industry standard wavelength for 1G multimode links. Compatible with the broadest range of installed fiber and patch cable inventory — no exotic media required.
• TAA Compliance: Required for federal GSA Schedule, DoD, and many state/local government IT contracts. The JL745A satisfies that requirement without a workaround or substitution.

Deployment Considerations:

• Confirm your existing fiber plant is LC-terminated before ordering — SC-terminated multimode runs will need LC pigtail adapters, which add a potential signal loss point.
• Third-party switch compatibility is not guaranteed. HPE Aruba firmware may suppress non-HPE-coded SFPs on certain platforms. If deploying in mixed-vendor environments, validate against your specific switch model and firmware version before committing to a large order.

Best fit: government or education IT infrastructure teams running HPE Aruba switching fabrics who need TAA-documented 1G uplinks across existing multimode fiber — particularly on GSA Schedule or cooperative purchasing contracts where TAA documentation is a line-item requirement.
