Gigabit Single-Mode Single-Fiber Transceiver with Two Ports

Gigabit single-mode single-fiber SFP transceivers provide 1Gbps Ethernet connectivity over long distances with hot-pluggable, multi-port flexibility for enterprise and industrial networks.OverviewGigabit single-mode SFP (Small Form-factor Pluggable) transceivers are modular devices that convert electrical signals from network equipment into optical signals suitable for single-mode fiber. They are designed for long-distance communication, typically supporting spans from 10 km up to 180 km, depending on the model and wavelength used . These transceivers are hot-swappable, allowing installation or replacement without powering down the network, which is ideal for multi-port switches and routers in high-availability environments .Key FeaturesData Rate: 1 Gbps full-duplex Ethernet, compliant with IEEE 802.3 standards .Fiber Type: Single-mode fiber (SMF) for long-distance transmission; some models support single-fiber BiDi (bidirectional) links using a single strand of fiber for both transmit and receive .Connector Types: LC Duplex or LC Simplex connectors, depending on the module type .Distance Support: Standard single-mode SFPs cover 10 km (1000BASE-LX/LH), extended models up to 40 km (1000BASE-EX), and long-haul models up to 70 km (1000BASE-ZX) with appropriate optical budgets .Compatibility: Works with Cisco, Intellinet, and other MSA-compliant switches and routers, ensuring interoperability across multiple vendors .Durability: Metal housing reduces electromagnetic interference and enhances reliability in dense multi-port deployments .Digital Optical Monitoring (DOM): Some modules provide real-time monitoring of optical power, temperature, and voltage for network management .Multi-Port DeploymentThese transceivers are ideal for multi-port network setups, such as access-layer switches, aggregation switches, or server connections. Their compact SFP form factor allows multiple transceivers to be installed in a single switch chassis, maximizing port density without increasing rack space . BiDi single-fiber modules are particularly useful when fiber availability is limited, as they allow two-way communication over a single strand.Use CasesEnterprise campus networks requiring long-distance fiber links between buildings.Industrial networks where high reliability and hot-swappable modules are critical.Legacy infrastructure upgrades where 1G connectivity is sufficient and cost-effective.Multi-vendor environments needing standardized SFP modules for interoperability.SummaryGigabit single-mode single-fiber SFP transceivers offer flexible, reliable, and long-distance 1Gbps connectivity. Their hot-pluggable design, multi-port compatibility, and vendor interoperability make them suitable for enterprise, industrial, and campus networks where high-density fiber connections and long-reach links are required .
