Nowadays, 10Gbps links for individual streams cannot satisfy subscribers’ requirements for higher-bandwidth data transmission. Increasing networking applications are driving 40GbE to ensure better performance. 40G QSFP+ transceiver has proved itself as an ideal solution for supporting 40 Gigabit Ethernet. There are so many 40G transceivers in the market, of which HP transceivers are the most commonly used transceivers. The following passage will introduce 40GbE transceiver modules and HP QSFP+ active optical cable in details.
Shedding Light on 40G QSFP+ Modules
The 40G QSFP+ module is a compact, hot-pluggable transceiver used for data communications applications. It supports Serial Attached SCSI, 40G Ethernet, QDR (40G) and FDR (56G) Infiniband and other communications standards. Compared with SFP+ modules, QSFP+ transceiver increases the port-density of 3-4 times. Take HP QSFP+ transceivers an example, compatible HP 721067-B21 (see in Figure 1) transceiver modules are very suitable for short distances and offer a very cost-effective way to establish a 40-gigabit link between QSFP port and SFP+ port of HP switches within racks and across adjacent racks.

What Are Features of 40G QSFP+ Modules?
- Hot-pluggable input/output device that plugs into a 40 Gigabit Ethernet QSFP port
- High-speed electrical interface compliant to the IEEE 802.3ba standard
- Certified and tested on QSFP 40G ports for superior performance, quality, and reliability
- Digital Diagnostics Monitoring Interface
What’s more, QSFP+ modules provide 40Gb/s Ethernet data rates over MMF (Multi-Mode Fiber) optic cable and SMF (Single-Mode Fiber) optic cable. QSFP+ modules take up very little space on a switch or server interface, allowing vendors to provide multiple QSFP+ ports in the same space.
HP 40GbE Optical Devices
HP offers a variety of 40GbE optical devices, such as QSFP to Four SFP+ copper breakout cables, QSFP+ transceivers, QSFP to Four SFP+ active optical breakout cables, QSFP to QSFP active optical cables, etc. Each has its unique characteristics. Let’s take 720208-B21 (QSFP+ to QSFP+ Active Optical Cable) for an example, image below gives you a vivid impression of QSFP+ to QSFP+ Active Optical Cable.

HP QSFP+ to QSFP+ active optical cables are suitable for 40G Ethernet. And there are two common active optical cables available in the market—QSFP to 4 SFP+ breakout AOC and QSFP to QSFP AOC. QSFP to 4 SFP+ breakout AOC is a 4×10 Gb/s parallel active optical cable that transmits four separate streams of 10 Gb/s data over ribbon cables in a point-to-multipoint configuration. This cable contains a QSFP+ module on one end and four separate SFP+ modules at the other ends. The latter is a 40 Gb/s parallel active optical cable which transmits error-free parallel 4×10 Gb/s data over multi-mode fiber (MMF) ribbon cables.
