A Supplier & Manufacturer of SFP Optical Transceivers

Multiple users in various geographic locations need to be linked via optic cable to achieve safe connectivity over the vast distances involved in today's networking environment. Due to the reason that the physical space that they occupy is usually quite limited, therefore portable devices are needed. The market for SFP transceiver modules has risen in recent years as a result of this particular, as well as other fast-changing requirements.

A fiber optic module that slots into a dedicated SFP socket or port on an Ethernet switch is known as a Small Form Factor Pluggable (SPF). This permits smooth transmission and the receiving of data by converting Ethernet signals into optical signals. The SFP module by design, which is also known as a mini GBIC (gigabit interface converter), is a hot-pluggable transceiver commonly used in telecommunications as well as data transmitting applications. People can connect both the optical modules and copper cables to a SFP terminal.

As the latest development, several network part suppliers have built and further endorsed it. The SFP transceiver module is defined by a multi-source arrangement, in contrast to being standardized by any official standards body (MSA). There are other networking protocols supported by the SFP module, which includes SONET, Gigabit Ethernet, Fibre Channel to name a few. Furthermore, due to its limited scale, SFP has largely replaced GBIC in most practical applications scenarios.

Optical modules as standard, usually have an electrical interface on one of its side that connects to the system's internal wiring. Then, it has an optical interface on the other side that connects to the outside world through a fiber optic cable. A multi-source arrangement is commonly used to specify the form factor and electrical interface by an interested party (MSA).

You may plug optical devices into either a front panel or an onboard socket. An electronic interface module, which incorporates either an active or passive electrical link to the outside world, may also act as a substitute for the optical module. Optical modules are manufactured and used by a vast industry.

Functions of SFP Transceivers

  •   ● SPF modules facilitate high-speed networking between switches and network components such as routers and other equipment.
  •   ● Copper or fiber optic cables are the most popular applications.
  •   ● Its compact size makes it suitable for places that aren't readily available.
  •   ● Simplex and duplex multimode or single-mode fiber optic cable are also compatible.
  •   ● Multimode wavelengths up to 1310nm and Singlemode wavelengths up to 1550nm are supported.
  •   ● A “+” version, which is a newer version of SFP, has been designed to have extremely fast speeds of up to 10Gbps.

Single-Mode vs. Multi-Mode SFP Transceivers

There are a few key differences (MMF SFP) between single-mode SFP (SMF SFP) and multimode SFP. The first is the fiber cable that they use. The heart of single-mode fiber is smaller than that of multimode fiber, allowing for unrestricted bandwidth and lower loss. Multimode fiber, on the other hand, can transmit various light modes.

The propagation distance is the second one to consider. Singlemode SFP transceivers are commonly used in long-distance connections up to 120 kilometers, while people use multimode SFP modules in short-distance links. Last but not least, there's the financial aspect. Owing to the use of multiple light-emitting units, single-mode SFP is more costly than multimode SFP.

SFP vs. SFP+ Optical Transceivers

The scale and behavior of SFP and “+” versions are the same. The primary distinction between them is that SFP is typically used in 100Base or 1000Base implementations, while “+” is typically used in Gigabit Ethernet applications. They also have varying data rates and propagation distances. For example, SFP supports Fibre Channel transceivers with speeds up to 4Gbps, while the “+” version supports speeds of up to 10.3125Gbps.

Onis Networks is one of the leading SFP transceiver suppliers for various ranges, types, and shapes. We have studied and understood the market for transceivers and recognize the importance of SFP modules in various industries. We only provide products that meet the IEEE standards. You can check the features of the products before making your purchase.

Types of SFP Optical Transceiver Modules

SFP transceiver modules are classified into various categories based on various classification criteria. According to the cable form, single-mode SFP modules and multimode SFP modules are available, allowing users to choose the necessary transceiver based on the network's required optical range. SFP modules have transfer rates ranging from 100Mbps to 4Gbps or more. These SFP transceiver modules can work at distances ranging from 500 meters to 100 kilometers. For WDM connections, CWDM and DWDM SFP modules are also available.

Ethernet switches, routers, firewalls, and NIC cards all have SFP ports. SFP modules are used to link network devices to fiber or copper network cables such as Cat5e. Other SFP transceiver modules are also used in HD cameras and monitoring devices, such as 3G video SFP and 12G video SFP.

SFP Transceiver Prices

Third-party SFP transceivers are less expensive than Cisco SFP or other brand SFP units. Except for the price, there is no difference in output between compatible 1G SFP and OEM SFP modules under normal conditions. As a result, compliant SFP modules are in high demand on the market. Users will find the right compliant SFP transceiver modules for their needs at a low cost from reputable retailers.

Consider Below When Choosing the Right SFP Transceiver Modules

When it comes to purchasing SFP modules, many people choose Cisco SFP modules. However, as the industry grows in popularity, a slew of third-party vendors has begun to sell cheaper SFP modules that work similarly to Cisco SFP.

  •   ● Check the connectivity of the module with the cable and switch port. The abbreviations mentioned above will aid in determining this aspect.
  •   ● Confirm whether Multimode or Singlemode modules are needed.
  •   ● Check to see how it complies with IEEE guidelines.
  •   ● Calculate the distance or surface that needs to be covered. You can choose between short-distance and long-distance data transfer based on this.
  •   ● What kinds of environmental conditions do you need to consider? Take into account the working temperatures in your application and make your selection accordingly.
  •   ● Check for features like electrostatic discharge safety, in addition to the operating temperature range.
