The SFP28 25GBASE-ER 1310nm 40km Industrial Module, Ericsson is used in 25G Ethernet, data center interconnect and 5G transport networks, where it provides a 25.78Gbps link over SMF up to 30km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards compliance covers SFF-8472, SFF-8432, SFF-8431. The unit works in any equipment with a standard SFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
To order, quote SFP-25GER-31-I together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
