1.25G BiDi SFP Transceiver Modules: Doubling Bandwidth with a Single Strand

In the realm of fiber optic networking, 1.25G BiDi SFP transceiver modules have emerged as a cost-effective and efficient solution for transmitting data over long distances. Their unique bi-directional capability, utilizing a single strand of single-mode fiber (SMF), has transformed the way we approach data communication, offering significant advantages over traditional transceivers.

What are 1.25G BiDi SFP Transceiver Modules?

1.25G BiDi SFP transceiver modules, also known as small form-factor pluggable (SFP) transceivers, are compact devices designed to transmit data bidirectionally over a single strand of SMF. This bidirectional capability allows data to flow in both directions simultaneously, effectively doubling the bandwidth utilization of the fiber cable.

Types and Specifications of 1.25G BiDi SFP Transceiver Modules

1.25G BiDi SFP transceiver modules adhere to the SFP MSA (Multi-Source Agreement) standard, ensuring compatibility with a wide range of network equipment. They are typically classified into two main types based on their maximum transmission distance:

• 1.25GBASE-BX10-D: These transceivers support a maximum transmission distance of 10 kilometers (km) over SMF.
• 1.25GBASE-BX20-D: Designed for extended-reach applications, these transceivers can transmit data up to 20 km over SMF.

In addition to these two primary types, there are also specialized 1.25G BiDi SFP transceivers available with enhanced features, such as advanced optical diagnostics and support for extended operating temperature ranges.
