BiDi SFP+ changes the geometry: each module uses a single fiber pair directionally separated by wavelength, so you can run one strand where you previously needed two. One of the most common decisions network engineers face is selecting between single fiber SFP and dual fiber SFP modules. This comprehensive guide explores the differences between single and dual fiber SFPs, their respective benefits, limitations, and use cases—helping you make an informed choice. A single fiber SFP, also known as a BiDi SFP, is designed precisely for this purpose—enabling bidirectional data transmission over a single strand of optical fiber. Unlike traditional SFP transceivers that require two fibers—one for transmitting and one for receiving—a single fiber SFP uses. SFP (Small Form-factor Pluggable) is a compact, hot-pluggable network interface module used to connect network devices (switches, routers, firewalls) to fiber optic or copper cables. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper. Both transmitting and receiving need one optical fiber to connect. Simplex SFP modules, also known as BIDI transceiver, employs a unidirectional transmission mechanism and have only one port. In practice, that means fewer splice points, smaller patch panels, and less conduit congestion—especially in retrofit buildings.

SFP transceivers are available with a variety of transmitter and receiver specifications, allowing users to select the appropriate transceiver for each link to provide the required optical or electrical reach over the available media type (e.g. or copper cables, or cables). Transceivers are also designated by their transmission speed. SFP modules are commonly available in se.

This SFP module provides 20km transmission distance over single-mode fiber at a nominal wavelength of 1310nm. The transmitter section uses a 1310nm FP laser that is a class 1 laser compliant according to International Safety Standard IEC 60825. A 1310nm optical module lets you move data efficiently through fiber optic communication networks. As part of the O-band (1260–1360 nm), it balances low dispersion, stable performance, and cost efficiency. This makes it widely adopted in data centers, enterprise backbones, and metro access. The transmission distance of optical modules is divided into short distance, medium distance, and long distance. Transmission distances greater than or equal to 30km are considered long-distance transmissions. Light commonly used in optical fiber is 850nm. The GPON OLT SFP transceiver provides an asymmetric 1. 244Gbps upstream and 2. 488Gbps downstream, reaching a link up to 20km over SMF via SC/UPC connector.
