LOGILINK SFP003 modulo ricetrasmettitore SFP BiDi 1.25Gbps, TX1310/RX1550nm, 20km, LC single-mode

Network administrators expanding a Gigabit Ethernet fiber backbone need reliable long-haul connectivity without running extra fiber pairs. This LOGILINK SFP BiDi transceiver uses a single strand of single-mode fiber to transmit at 1310 nm and receive at 1550 nm, delivering a full 1.25 Gbps link over distances up to 20 km. The LC simplex connector keeps installations compact, while SFP MSA compliance guarantees broad compatibility with switches, routers, and media converters.

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Transceiver type: BiDi (bi-directional) single-fiber
• Data rate: 1.25 Gbps
• Wavelength: 1310 nm transmit / 1550 nm receive
• Connector: LC simplex
• Fiber type: Single-mode (OS2)
• Maximum distance: 20 km
• Standards: IEEE 802.3z (1000BASE-BX)
• DDM/DOM support: Yes
• Hot-pluggable: Yes
• Operating temperature: 0°C to 70°C
• MTBF: >50,000 hours

Why choose it

By using only one fiber strand, this transceiver halves your cabling requirements and makes efficient use of existing infrastructure. The SFP MSA form factor allows mixing and matching with other compliant modules and is hot-swappable, so you can replace or upgrade ports without powering down your switch. With effective DDM monitoring, you can track optical power levels and diagnose the link in real time. It is built to commercial temperature standards and tested to a long MTBF for worry-free operation.

Ideal use cases

• Point-to-point Gigabit Ethernet links between buildings
• Carrier and enterprise networks needing 20 km reach
• Single-fiber applications to conserve fiber capacity
• Upgrading legacy SX/LX networks to BiDi through existing single-mode cabling

Good to know

Pair this module with a complementary BiDi transceiver that uses the opposite TX/RX wavelengths (1550 nm TX / 1310 nm RX) at the far end. For proper attenuation, keep the optical budget within the 20 km range and use OS2 single-mode fiber. The module is RoHS compliant and backed by certification to CE and FCC standards.
