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. Among the most commonly used fiber types are single-mode fiber (SMF) and multimode fiber (MMF), often paired with 1310nm SFP modules for high-speed data transmission. In this guide, we will explore the distinctions between 1300nm and 1310nm transceivers, examine the characteristics of SMF and MMF. When engineers search for “SFP wavelength,” they are typically trying to answer a practical deployment question: Which optical wavelength should I use—850 nm, 1310 nm, or 1550 nm—and why does it matter? The answer directly affects fiber compatibility, transmission distance, link stability, and. A two-fiber otpical transceiver with an SFP form factor for 1G Ethernet complies with the 1000Base-SX standard. Designed to work in multimode optical fiber (Multi mode fiber, MMF), maximum range 2km when using OM2+ cable, optical budget 12dB, LC connector, operating wavelength 1310nm. DDM function. The BO05A136 100BASE-FX LC Duplex SFP compatible with Standard Code (Cisco) has a receiving function (receiver with 1310nm) and a transmitting function (transmitter with 1310nm) for the transmission of optical signals via multimode fiber, taking the respective transmission protocol into account.
