Introduction

In this article, we will briefly introduce the 1000BASE-BX-D Ethernet standard and its optical transceivers compatible brands and basic solutions, so that allows viewers to have a more profound understanding for 1000BASE-BX-D technology, better to understand the basic solutions to 1000BASE-BX-U. Also to see which brands can be compatible with Cozlink transceivers, helping buyers to buy both compatible and cost-effective products.

What is the 1000BASE-BX-D technology?

1000BASE-BX-D is capable of up to 10 km over a single strand of single-mode fiber, with a different wavelength going in each direction. The terminals on each side of the fibre are not equal, as the one transmitting downstream (from the center of the network to the outside) uses the 1490 nm wavelength, and the one transmitting upstream uses the 1310 nm wavelength. This is accomplished using a passive splitter prism inside each transceiver.

1000BASE-BX-D compatible brands:

Cozlink products and services: a convenient shopping platform, custom Logo, packaging, etc.

What are the Difference Between 1000BASE-BX-UD and 1000BASE-EX?

The 1000BASE-BX-D SFPs, compatible with the IEEE 802.3ah 1000BASE-BX10-U standards, operate on a single strand of standard SMF. A 1000BASE-BX10-D device is always connected to a 1000BASE-BX10-U device with a single strand of standard SMF with an operating transmission range up to 10 km. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices as depicted in Figure 2: 1000BASE-BX10-D transmits a 1490-nm channel and receives a 1310-nm signal, whereas 1000BASE-BX10-U transmits at a 1310-nm wavelength and receives a 1490-nm signal. As shown, the presence of a wavelength-division multiplexing (WDM) splitter integrated into the SFP to split the 1310-nm and 1490-nm light paths.

The 1000BASE-EX SFP operates on standard single-mode fiber-optic link spans of up to 40 km in length. A 5-dB inline optical attenuator should be inserted between the fiber-optic cable and the receiving port on the SFP at each end of the link for back-to-back connectivity.

Conclusion

Due to the different brand is only applicable to their own devices, makes third-party compatible optical transceiver is very important, it ensures that two different brands of equipment are compatible with each other. Cozlink transceiver has high performance; it can fully compatible with different brands, and Cozlink price is much less than the original manufacturer, so it is a perfect third-party compatible optical transceiver for 1000BASE-BX-U Ethernet standard solution. Apart from transceivers,  Cozlink also provides all kinds of patch cords, pigtails, high speed cables for your choice.
