QSFP+ Transceiver

QSFP+ (Enhanced Quad Small Form-factor Pluggable)is a 4-channel small hot pluggable optical transceiver that supports LC Duplex and MPO-12 fiber connectors. Launched in 2012 it is larger in dimensions that SFP+ optical transceivers and covers distances of between 100m and 40km. It is the main and dominant form factor for data rates at 40 Gbps.

Multimode Optical Transceivers

Multi-mode transceivers transmit multiple signals at shorter distances (up to 2km) over a larger core cable. 100Mbps Fast Ethernet can be transmitted up to 2km and Gigabit up to 550m. However, the larger the bandwidth the shorter the distance the signal can be transmitted. For example: 10 Gbps up to 300m, 40 Gbps and 100 Gbps up to 100m.

Non-Return-to-Zero (NRZ) Optical Transceiver Modulation

Non-Return-to-Zero (NRZ) is the traditional modulation for optical communication. It uses on-off keying (two voltage levels to represent binary ‘0’ and’1’). It is used for short distances and limited to 28Gbps data rate but using WDM can be combined to achieve a data rate of 100Gbps.

VCSEL (Vertical-Cavity Surface-Emitting Laser)

VCSEL stands for Vertical-Cavity Surface-Emitting Laser and is a semiconductor laser, rather than an edge-beam laser. It uses the 850nm wavelength for transmission over multimode fiber. VCSEL lasers are inexpensive to make, have low power consumption and are used in optical transceivers for distances up to 500m.

40G Ethernet

Originally introduced in 1980 Ethernet was followed in 1995 by Fast Ethernet and Gigabit Ethernet in 1998 following the 1000BASE-T (or IEEE 802.3ab) cabling standard for transmission of Ethernet frames over twisted pair at 1Gbps. Gigabit Ethernet transmission is also possible over shielded balanced copper cable (1000BASE CX) and optical fiber (1000BASE-X). Various optical fiber options are available: This optical transceiver is 40G Ethernet.

40G QSFP+ at seesuo.com

The 40-Gigabit QSFP+ transceiver module is a hot-swappable, parallel fiber-optical module with four independent optical transmit and receive channels. These channels can terminate in another 40-Gigabit QSFP+ transceiver, or the channels can be broken out to four separate 10-Gigabit SFP+ transceivers. The QSFP+ transceiver module connects the electrical circuitry of the system with either a copper or an optical external network. FiberOnSale supply high quality QSFP+ transceivers which are used primarily in short reach applications in switches, routers, and data center equipment. These modules provide higher density than SFP+ modules. We also provide 40G CFP transceiver module. For more information, pls contact us.

FAQ:

What Are the Interfaces of QSFP+ Module?

QSFP+ transceivers are designed to install into any QSFP+ port (and part of QSFP28 port), allowing for 40GBASE-X interfaces to the network through the QSFP+ connector. Generally, the interfaces of 40G QSFP+ modules can be either duplex LC or MTP/MPO (short as "MTP" in the following introduction). There are some distinct differences between the two interfaces: transmission distance, cable type, and availability of 4x10G connectivity, etc. If you want to get more information about the analysis and comparison of the two interfaces, please visit: 40G QSFP+ MTP vs 40G QSFP+ LC Transceivers.

The working principle of 40GBASE-LR4 transceivers

40GBASE-LR4L

40GBase-LR4L, namely 40GBase-LR4 Lite, has the same fundamentals as the 40GBase-LR4. Both of them are used for long-range 40G data transmission over single mode fiber cable. The major distinction is that the LR4L module can only reach up to 2 km in transmission distance.

40GBASE-ER4

The last QSFP+ module that will be introduced can handle the longest transmission distance of data up to 40 km over SMF with duplex LC connectors. It has the same working principle as 40GBASE-LR4 mentioned before.

Which transceiver can support 40Gbps?

Optical transceivers with QSFP+ or QSFP28 interface
Optical transceivers with QSFP+ or QSFP28 interfaces are capable of supporting 40Gbps data transmission. These transceivers are designed to meet the high-speed networking requirements of modern data centers and provide reliable and efficient connectivity.

What is the difference between QSFP 40G LR4 and QSFP 40G LR4 S?

While the 40GBase-SR4 is used for short distance transmission, the 40GBase-LR4, on the other hand, is for long range transmission of data.
