What is a 1G optical transceiver?
1G optical transceiver is a transceiver series that supports 1.25G and 1G Fiber channel data rates. It is the most popular type in the market and is perfect for use in any location. 1G Optical transceivers come in both commercial and industrial versions so that you can use them indoors or outdoors. The main types include 1G 1×9 transceiver, 1G SFP transceiver, 1G SFF transceiver, 1G CWDM transceiver, 1G DWDM transceiver, and 1G GBIC transceiver.
Key Features
When choosing a 1G optical transceiver, you’ll want to ensure that it has the needed features. Some of the key features include:
- High data transmission rates: 1G optical transceivers can handle data transmission rates of up to 1.25Gbps, which is more than enough for most enterprise applications.
- Excellent quality: In addition to high data transmission rates, 1G optical transceivers offer excellent link quality, meaning that you’ll be able to transmit signals without disruptions or dropped connections.
- Easy installation: 1G optical transceivers are easy to install, making them an excellent option for any network upgrade.
- Low cost: 1G optical transceivers are generally much cheaper than other transceivers like SFP+ and QSFP28, which means they’re an excellent option for budget-conscious users.
- Multiple form factors: SFP, SFF, 1×9, and GBIC form factors for different applications and customers
1G SFP transceiver
1G SFP transceivers are designed for high-speed transmission and are an excellent choice for 1G networking applications or video streaming over long distances. They provide low latency and are perfect for rugged environments. Optcore 1G SFP transceivers interface with various networking equipment and connect multiple devices. Additionally, they are easy to replace and have plug-and-play support. Compare this with the 1×9 transceiver, which has plug-and-play support, is easy to replace, and has a DDM function.
1G CWDM&DWDM transceiver
Today’s data-driven world requires high-density, low latency, and comprehensive bandwidth transceivers to support modern applications. Optcore’s 1G CWDM&DWDM transceiver solutions offer these benefits and more. This technology is perfect for building highly scalable network solutions for mobile and fixed applications.
1G SFF Transceiver
SFF 2×5 and 2×10 electrical pinout transceiver is designed for high-speed transmission of digital signals over long distances. This small form factor transceiver is ideal for rugged and outdoor applications where size, weight, and power consumption are important factors.
However, SFF is an obsolete product, used only in special applications and for special equipment such as industrial switches. Furthermore, there are no plug-and-play support options for this transceiver. Compared to the SFP form factor, it has a higher price and less compatibility with various networking equipment.
