10G Fronthaul SFP+ 2km SMF Industrial Transceiver: 10GFH-SFP-2I

The 10GFH-SFP-2I is a 10G CPRI/OBSAI fronthaul SFP+ built for the short single-mode link between a baseband unit and a remote radio head. It transmits and receives at 1310nm over duplex single-mode fiber using a Fabry-Perot laser and a PIN photodiode, a combination matched to the roughly 2km reach this part is rated for.

The module carries the full CPRI rate ladder, option 2 through option 8, from 1228.8 Mbps to 10.138 Gbps. It also supports OBSAI RP3 x2, x4, and x8 at 1.536, 3.072, and 6.144 Gbps. Together these rates cover the radio interface line rates used across 4G and LTE fronthaul deployments. This is a dedicated CPRI/OBSAI fronthaul optic and does not carry Ethernet traffic.

Optical performance is set for the short fronthaul span. TX power ranges from −8.2 to +0.5 dBm and RX sensitivity is −14.4 dBm, with an RX overload point of +0.5 dBm. The module is rated for a 6.3 dB link budget over single-mode fiber, with chromatic dispersion tolerance of 70 to 100 ps/nm across the 2km reach. A duplex LC/UPC connector terminates the fiber, and the module runs from a single +3.3V supply.

The defining feature of this variant is its industrial temperature rating of −45°C to +85°C. Fronthaul radios sit in outdoor cabinets, on rooftops, and on towers, where commercial-grade optics rated to 0°C or −5°C are not enough. The extended low-temperature floor lets the module start and run reliably through cold-weather sites that the standard 10GFH-SFP variants are not rated for.

Digital optical monitoring reports TX power, RX power, laser bias, temperature, and supply voltage in real time, so a network operations team can watch a fronthaul link from the management system rather than sending a technician to the radio site. The module complies with the SFP MSA and SFF-8431, and meets CE, RoHS, and Class 1 laser safety under IEC60825-1 and the FDA standard.

Most RAN vendors validate the SFP+ vendor identifier before a CPRI link comes up. The 10GFH-SFP-2I is the multi-vendor base part behind EdgeOptic's vendor-coded fronthaul transceivers, including the Ericsson RDH 102 65/2 and Nokia 475338A.101 compatibles, each programmed with the EEPROM identifier its base station expects. One physical part covers multiple radio platforms by changing the coding rather than the optics.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. The 10GFH-SFP-2I is made to order with a 2-week lead time and ships with a lifetime warranty. To match this module to a specific radio platform or to order a vendor-coded variant, contact our sales team.
