HPE BladeSystem 455883-B21 Compatible 10G SFP+ SR transceivers are high-performance, cost-effective modules supporting a data rate of 10.3 Gbps. The transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA), and an MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement and SFF-8472 digital diagnostics functions.

Frequently Asked Questions About 10GBASE-T SFP+ Module
Q: What cables are supported with 10GBASE-T SFP+ modules?
A: The module is compatible with 10GBASE-T, 1000BASE-T, and 100BASE-T. The Supported cables as below:
| Speed | Cable Type | Max. Cable Distance |
|---|---|---|
| 10GBASE-T | Cat 6a | 30m-50m |
| Cat6a shielded/Cat 7 | 80m-100 m | |
| 1000BASE-T / 100BASE-T | Cat 6/Cat 6a /Cat5e | 100m |
Q: Can the 10GBASE-T be used at low temperatures?
A: The 10GBASE-T is available in commercial and industrial versions. Standard products are suitable for operating temperature range of 0~70 °C. For a wider temperature range, it is recommended to purchase industrial modules (-40 to 85°C) .
Q: What are their differences of 10GBASE-T SFP+ vs SFP+ DAC vs Fiber SFP+?
A:10GBASE-T SFP+, SFP+ DAC, and SFP+ Transceiver are the most commonly used types in the 10G network.
| Comparsion | SFP+ DAC | 10GBASE-T SFP+ | SFP+ Fiber |
|---|---|---|---|
| Media | Integrated copper/fiber | Category 6a or 7 | Fiber Cable (SM/MM) |
| Connector | SFP+ | RJ45 | LC |
| Distance | 15m | 30m-100m | Max 100km |
| Cabling System | No | Copper cabling | Fiber cabling |
| Data rate | 10 Gbps | 10 Gbps | 10 Gbps |
| Power Consumption | 1~1.5w | 2~5w | ~0.7w |
Q: Where can 10GBASE-T be used?
A: If using 10GBASE-T, the places are required to be in the Data Center or horizontal areas (in building, including wiring closet). But it is not suited for vertical (riser links) applications within building, or campus & metro applications.
The 10GBASE-T modules are used in Data Center TOR areas.
Cases for 10GBASE-T Ethernet Connections
When the two switches both have SFP+ and 10GBASE-T ports, it is recommended to use the 10GBASE-T copper ports first, and save the SFP+ ports for possible future connections to an optical network for longer transmission distance.
