100Gbps QSFP28 Connectivity

R0Z30A delivers 100Gbps optical connectivity through a compact QSFP28 module. It is designed for high-throughput connections between data center switches, aggregation switches, core switches and other compatible 100GbE equipment.

100Gbps bandwidth makes the module suitable for modern enterprise networks where 10GbE and 40GbE uplinks no longer provide sufficient capacity.

CWDM4 Optical Technology

The R0Z30A uses 100G CWDM4 technology with four optical lanes. The four wavelengths occupy separate portions of the 1310nm optical window and are multiplexed onto a duplex single-mode fiber connection.

Aruba documentation identifies the four wavelength ranges as approximately 1264.5–1277.5nm, 1284.5–1297.5nm, 1304.5–1317.5nm and 1324.5–1337.5nm. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/Switches/xcvrs/xcvr_guide/Content/Chp_qsfp28/qsf-lc-mod-spe.htm))

2km Transmission Distance

The R0Z30A supports a maximum transmission distance of 2km over compatible single-mode fiber. HPE's official specifications list 2km as the maximum distance. ([HPE](https://www.hpe.com/us/en/product-catalog/options/pip.specifications.aruba-100g-qsfp28-lc-cwdm4-2km-smf-transceiver.1011181799.html))

Actual link distance depends on fiber quality, optical attenuation, connector losses, patch panels and the total optical link budget.

Single-Mode Fiber Support

The R0Z30A is designed for 9/125µm single-mode fiber (SMF). Aruba's transceiver guide specifies SMF with an LC UPC connector and a 2km maximum reach. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/Switches/xcvrs/xcvr_guide/Content/Chp_qsfp28/qsf-lc-mod-spe.htm))

Use suitable single-mode duplex LC cabling and maintain the correct fiber polarity when deploying the module.

LC UPC Connector

The R0Z30A uses an LC UPC optical connector. This allows the module to connect to standard duplex LC single-mode fiber infrastructure.

Before installation, verify connector type, polarity and optical budget for the complete fiber path.

Four-Wavelength CWDM Architecture

Unlike single-lane 100G DR or LR optics, the R0Z30A uses four optical wavelengths to carry the 100Gbps signal. The four lanes are multiplexed over a duplex single-mode fiber connection.

This architecture allows the module to use standard duplex LC fiber while supporting 100Gbps transmission over distances up to 2km.

Optical Specifications

These optical parameters are documented in Aruba's QSFP28 transceiver guide. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/Switches/xcvrs/xcvr_guide/Content/Chp_qsfp28/qsf-lc-mod-spe.htm))

Digital Optical Monitoring

The R0Z30A supports Digital Optical Monitoring (DOM). When supported by the host switch and software, DOM can provide useful diagnostic information about optical module operating conditions and link performance.

Compatible HPE Aruba Networking Platforms

Aruba's official compatibility documentation lists R0Z30A across numerous QSFP28-capable platforms. Examples include the Aruba 6300, 6400, 8100, 8325, 8360, 8400, 9300, 9300S, 10000 and 10040 families, subject to the specific hardware model and minimum software release. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/Switches/xcvrs/xcvr_guide/Content/Chp_qsfp28/qsf-lc-mod-spe.htm))

For example, Aruba documentation lists R0Z30A support on the Aruba 6300 48p Smart Rate 10G PoE with 4x100G QSFP ports beginning with AOS-CX 10.13.1010, while the Aruba 6400 12-port 40G/100G QSFP28 module supports it from AOS-CX 10.07.0005. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/Switches/xcvrs/xcvr_guide/Content/Chp_qsfp28/qsf-lc-mod-spe.htm))

Compatibility depends on the exact switch model, QSFP28 port and software release. Always verify the target equipment before purchasing.

Campus and Data Center Applications

HPE Aruba's validated solution architectures use R0Z30A for 100Gbps links between aggregation and core switches. The documented examples include Aruba 8360 and 8325 platforms. ([Aruba Networking](https://arubanetworking.hpe.com/techdocs/VSG/docs/010-campus-design/esp-campus-design-060-reference-architectures/))

• Data center interconnects
• Core-to-core switch links
• Aggregation-to-core uplinks
• Campus backbone connectivity
• Enterprise network aggregation
• High-bandwidth switch uplinks
• Building-to-core links
• Data center leaf-spine connections

R0Z30A vs 100G LR4

R0Z30A should not be selected when a 10km optical reach is required. For a 10km 100G LR4 connection, a dedicated LR4 transceiver such as the Aruba JL310A is the appropriate product class.

R0Z30A vs 100G LR

These two modules are not interchangeable merely because both use QSFP28 and LC connectors. The host switch must support the specific optical technology.

Installation Considerations

Before deploying R0Z30A, verify that the target switch supports the exact transceiver and required software version.

• Confirm QSFP28 port compatibility
• Confirm R0Z30A support in the switch software
• Use 9/125µm single-mode fiber
• Use compatible LC UPC connectors
• Verify fiber polarity
• Check the optical link budget
• Keep the optical path within the 2km specification
• Ensure both ends use compatible 100G CWDM4 optics
