HPE Compatible SFP+ CWDM Modules

A

An HPE compatible SFP+ CWDM transceiver is a hot-pluggable 10 Gbps optical module that enables coarse wavelength division multiplexing on HP Enterprise switches over single-mode fiber.

A

It combines multiple 10 Gbps channels on one single-mode fiber by transmitting each signal on a distinct coarse wavelength spaced 20 nm apart, reducing fiber count and cost.

A

HPE compatible SFP+ CWDM modules are interoperable with HPE FlexNetwork and FlexFabric series switches, including Aruba 3810M, 5900AF, HPE 5130 EI, and 5500 EI models.

A

Standard wavelengths range from 1270 nm to 1610 nm in 20 nm increments, covering eight CWDM channels per fiber link for flexible network design.

A

Typical HPE compatible SFP+ CWDM modules support up to 80 km reach over ITU-T G.652 single-mode fiber; extended-reach variants can exceed 120 km.

A

Yes, they require ITU-T G.652 single-mode fiber to maintain low attenuation and optimal signal integrity over long distances.

A

Yes, these SFP+ CWDM transceivers support hot-swapping, allowing insertion or removal without powering down the switch or disrupting other links.

A

They support 10 Gbps per channel, fully compliant with IEEE 802.3ae 10GBASE standards for reliable high-speed connectivity.

A

Yes, they offer Digital Optical Monitoring (DOM) to report real-time optical power, laser bias current, temperature, and voltage metrics.

A

Insert the module into the SFP+ port until it latches, then connect LC single-mode fiber patch cables ensuring each wavelength matches the designated Mux/Demux channel.

A

They deliver up to 50% cost savings while ensuring full interoperability, backed by rigorous testing, warranty support, and compliance with HPE specifications.

A

Standard modules operate from 0 °C to 70 °C; extended-temperature versions cover –40 °C to 85 °C for harsh environments.

A

They undergo burn-in testing, optical eye-pattern analysis, BER testing, and compatibility validation on HPE platforms to guarantee performance and reliability.

A

Yes, they typically include a limited lifetime warranty covering manufacturing defects and performance issues under specified operating conditions.

A

Not directly—mixing CWDM and DWDM requires an appropriate WDM Mux/Demux to combine or separate channels without signal interference.

A

Choose the wavelength label matching your CWDM Mux/Demux port (e.g., 1470 nm) and ensure each link uses a unique channel to avoid crosstalk.

A

CWDM uses 20 nm channel spacing for up to eight cost-effective channels over shorter distances, while DWDM employs 0.8 nm spacing for up to 96 channels and longer-haul applications.
