1.25G SFP 200km Industrial SMF Transceiver Description
The 1.25G-SFP-200DI is a 1.25 Gbps SFP transceiver built for 200 km single-mode fiber links through duplex LC/UPC connectors. It pairs a 1550 nm DFB laser with an APD receiver, delivering an average link budget of 40 dB and a receiver sensitivity of -35 dBm against a receiver overload point of -7 dBm. Dispersion tolerance runs 3800 to 4300 ps/nm, matching the chromatic dispersion that accumulates over 200 km of single-mode fiber at this wavelength. Transmit power is specified between -2 dBm and +5 dBm, with a 37 nm spectral window (1528 to 1565 nm) around the 1550 nm nominal wavelength.
Supported data rates span 0.1 to 1.25 Gbps, covering Gigabit Ethernet, 100 Mbps Ethernet and 1G Fibre Channel at 1.0625 Gbps. Digital diagnostic monitoring reports transmit power, receive power, temperature, bias current and supply voltage, so link health can be checked without interrupting traffic. The module runs on a single +3.3V supply and follows the SFP MSA mechanical and electrical interface defined in INF-8074i.
The 200DI is rated for Industrial operation, -40°C to +85°C, compared with the 0°C to 70°C Standard-temperature rating of the related 1.25G-SFP-200D. All other optical and electrical specifications are identical between the two. The 200DI is CE marked, RoHS compliant, and Class 1 laser safety compliant under FDA and IEC 60825-1.
The 200DI is made to order. For volume pricing or configuration questions, contact our sales team.
Frequently Asked Questions
What is the difference between the 1.25G-SFP-200DI and the 1.25G-SFP-200D?
The 200DI and the 200D share the same optical specification: 1550 nm DFB laser, APD receiver, 40 dB average link budget, -35 dBm receiver sensitivity, 200 km reach over single-mode fiber, 3800 to 4300 ps/nm dispersion tolerance, duplex LC/UPC connectors and DDM support. The only difference between the two parts is operating temperature. The 200DI is rated Industrial, -40°C to +85°C. The 200D is rated Standard, 0°C to 70°C. The 200DI suits sites without climate control; the 200D suits a conditioned indoor environment.
What environments are industrial-temperature long-haul SFPs designed for?
Industrial-temperature optics in this class are typically specified for outdoor roadside cabinets, substations and utility SCADA links, railway and highway trackside equipment, and remote or mountainous power and grid-monitoring sites. These locations see wider temperature swings than a climate-controlled data center or equipment room, which is why the extended -40°C to +85°C rating is often the deciding factor over reach alone when choosing between the 200DI and the standard-temperature 200D.
