25G SFP28 LR 1310nm Industrial Optical Transceiver Module
Product Overview
The Apex 25G SFP28 LR industrial module is the 1310nm single mode 25 Gigabit interface built for equipment that sits outside a temperature controlled room. The optical link is the standard 25GBASE-LR 10km grade; what changes is the component set and the burn in, which take the module from 0 to 70C operation to a -40 to 85C rating.
Industrial temperature parts are specified where the module itself sees outdoor or plant conditions: remote radio cabinets, pole mounted enclosures, roadside and utility cabinets, unheated shelters and factory floors. In those places a commercial module can link up at commissioning and then drop out at midday in summer or on the first cold night, so the temperature rating is a link availability requirement rather than a marketing detail.
Every unit is burnt in and tested for optical power, wavelength, extinction ratio and error rate across the rated temperature range, reports live readings through DDM, and is coded for the host platform you name, whether that is a fronthaul port, an industrial Ethernet switch or a media converter. Commercial LR, ER, BiDi, CWDM and DWDM 25G parts are available from the same line.

Applications
Outdoor Radio and RRU Cabinets
Holds the 25G fronthaul or backhaul link where the module sits in a pole or cabinet enclosure and sees the full outdoor temperature swing.
Roadside, Utility and Traffic Cabinets
Keeps 25G aggregation links up in unheated street furniture, where commercial temperature optics are usually the first part to fail.
Industrial and Plant Networks
Links 25G switches, cameras and controllers in factories, yards and mines where the ambient temperature sits outside the commercial window.
Compatibility
Industrial 25G LR modules are coded to the host platform you specify, including fronthaul equipment, industrial Ethernet switches and media converters, and are tested on live ports before shipment. Two details decide whether a link needs this grade: the ambient temperature at the module rather than at the shelter door, and the temperature the host platform itself is rated for. Tell us both and we confirm the part and the coding.

Frequently Asked Questions
How is the industrial part different from the commercial 25G LR module?
The optical specification is the same 10km LR link. The industrial version uses components and burn in rated from -40 to 85C instead of 0 to 70C, so it survives pole cabinets, roadside enclosures and unheated shelters.
Which installations really need industrial temperature optics?
Anywhere the module sees outside conditions: RRU and pole cabinets, roadside and utility enclosures, unheated shelters and plant floors. If the module sits in an air conditioned room, the commercial grade is enough.
Is the industrial version coded the same way as the commercial part?
Yes. Coding follows the host platform, not the temperature grade, so an industrial spare behaves exactly like the commercial module in the same chassis.
Can you quote both temperature grades at the same time?
Yes. Send the platform, the quantity and the cabinet locations and we return pricing for the commercial and industrial parts together, so you can decide which sites justify the industrial cost.
