1000BASE-LX/LH SFP transceiver operates at a speed of 1.25 Gbps and uses a 1310 nm FP-style laser to connect over 9/125 µm single-mode fiber (SMF). The nominal reach of this transceiver is 10 km via duplex LC/UPC cabling. The optical interface for this transceiver is single-mode fiber (SMF) utilizing duplex LC cabling, which connects to the host (the port of the switch or router) via the small form-pluggable (SFP) host interface used for 1000BASE-X applications. The power supply specification or consumption voltage is certified for nominal use under 1000BASE-LX and is rated at +3.3 V single rail. The SFP transceiver is hot-pluggable and will fit in standard SFP cages or interfaces. The typical maximum power consumption of this device is likely 1 W and as a feature also includes built-in digital diagnostics per SFF-8472, which includes diagnostics such as: temperature, Vcc, laser bias current, TX optical power, and RX optical power.
The operating temperature specification (commercial) for the transceiver is rated from 0 to 70 degrees Celsius (32 to 158 degrees Fahrenheit). As per any laser certifications, this laser device classification is rated as a laser safety Class 1 device. This device is compliant with materials or production standards, RoHS (lead-free). This SFP is compliant with the IEEE 802.3z Gigabit Ethernet standard. The link type specification includes that it transmits at 1G – LX/LH over single-mode fiber and can use legacy multi-mode fiber (MMF) over a distance of up to 550 m, provided that the application uses a mode-conditioning patch (if applicable). The transmitter and receiver specifications meet the standard 10 km link budgets for both the LX and LH parts of the name.
The physical connector for this transceiver is the LC/UPC port. Media type is noted as SMF. Data rate is noted as 1.25 Gbps line rate. Furthermore, the device is built to support management and data access to DOM/diagnostics over I2C, which will help support data and diagnostics with the transceiver. The form factor is listed per the MSA mechanical/electrical envelope as SFP.
