25G Fronthaul LR SFP28 Industrial Transceiver Description
The EdgeOptic 25GFH-SFP28-10I is a multi-vendor compatible 25G Fronthaul LR SFP28 dual-fiber optical module built for medium-distance mobile fronthaul in demanding outdoor and industrial environments. With an industrial operating temperature range of −45°C to +85°C, it delivers reliable 10-kilometer connectivity over single-mode fiber for 5G and LTE deployments exposed to extreme conditions.
The module operates at 1310nm for both transmission and reception and supports data rates from 8.5 to 28.1 Gbps. This multi-rate range covers the relevant CPRI (Common Public Radio Interface) options: option 7 at 9.830 Gbps, option 8 at 10.138 Gbps, option 9 at 12.165 Gbps, and option 10 at 24.33 Gbps, which is the maximum CPRI rate this module carries. The same 25GBASE-LR transport also supports eCPRI over 25GbE for 5G NR fronthaul. Forward error correction runs in the host ASIC for signal integrity across extended fronthaul links.
Transmission uses a DML (Directly Modulated Laser); reception uses a PIN photodiode. The module holds an 8.3 dB optical link budget for reliable 10-kilometer transmission over single-mode fiber across the full temperature range. Transmit power runs from −5 dBm to +2 dBm over a 40nm wavelength bandwidth, with a minimum extinction ratio of 3.5 dB. Receiver sensitivity is −13 dBm with an overload point of +3 dBm.
This hot-pluggable SFP28 module presents a duplex LC/UPC optical interface. The electrical interface conforms to SFF-8431, SFF-8432, and the SFP28 MSA (Multi-Source Agreement), so it works in standard SFP28 host cages across multiple vendor platforms. The module can be programmed to the EEPROM coding of various network equipment manufacturers, which makes it a single universal part for mixed-vendor fronthaul fleets.
DDM/DOM (Digital Diagnostic Monitoring) reports transmit and receive optical power, module temperature, laser bias current, and supply voltage in real time over the I2C interface, which supports proactive maintenance in unattended outdoor sites. Maximum power consumption is 1.2W from a +3.3V single supply.
The −45°C to +85°C industrial operating range suits outdoor cabinet installations, cell tower equipment shelters, and remote radio unit deployments. Compliance covers 25GBASE-LR and IEEE 802.3cc, and the module is CE marked and RoHS compliant.
Typical applications include outdoor 5G fronthaul links, C-RAN deployments in harsh environments, remote cell site backhaul, and industrial mobile network infrastructure where commercial-grade modules cannot tolerate the temperature extremes.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Every module ships with a lifetime warranty. This part is made to order on a 2-week lead time. For vendor coding, volume fronthaul builds, or project pricing, contact our sales team.
Frequently Asked Questions
Does 25GBASE-LR require FEC on the host switch or router?
Yes. The module supports host FEC but does not run FEC itself. For 25GBASE-LR, RS-FEC (RS(528,514), IEEE 802.3 clause 108) runs in the host ASIC and should be enabled on the host port for reliable 10km operation. This applies whether the link carries CPRI, eCPRI, or standard 25GbE traffic.
Can this module carry both CPRI and eCPRI, and what is the highest CPRI option it supports?
The 8.5 to 28.1 Gbps multi-rate range covers CPRI options 7 (9.830 Gbps), 8 (10.138 Gbps), 9 (12.165 Gbps), and 10 (24.33 Gbps). Option 10 is the ceiling; the module does not support a higher CPRI option. eCPRI is also supported because it runs over the 25GbE transport that 25GBASE-LR provides, which makes the module suitable for both legacy CPRI and 5G NR eCPRI fronthaul.
Why does this fronthaul module need an industrial temperature rating, and how does the -10I differ from the -10?
Fronthaul optics often sit in outdoor RRU cabinets, cell tower shelters, and unheated enclosures where temperatures swing well below 0°C in winter and climb under summer load. Commercial-grade SFP28 modules (0°C to +70°C) are not specified for those conditions. The 'I' in 25GFH-SFP28-10I marks the industrial build, rated for an operating range of −45°C to +85°C, so it stays within spec in harsh outdoor sites. The 25GFH-SFP28-10 is the commercial-temperature variant of the same optical design; verify its exact temperature range on its own product page before substituting one for the other. Reach, link budget, CPRI support, and FEC behavior are otherwise identical.
