Product Description
The Cisco SFP-25G-LR-S compatible SFP28 transceiver provides 25GBase-LR throughput up to 10km over single mode fiber (SMF) using a wavelength of 1310nm via an LC duplex connector. Featuring low power consumption, high speed, this 25G transceiver is ideal for 25G Ethernet, telecom, and data center. Besides, it offers interoperability, laying a foundation for the next-generation network upgrade. Each SFP28 transceiver module is individually tested in targeted switch, it is fully compliant with the SFP28 MSA, CPRI and eCPRI standard.
Note: The FS P/N is changed from SFP28-25GLR-31 to SFP-25GLR-31, but the product is the same. Only the FS P/N has been changed.

Applications
R&D team consists of experts with years of experience in the optical communications industry. Our manufacturers are top-class in the industry and support an OEM product. Installing a third-party transceiver does not affect your network equipment.
Q: Is the SFP-25GLR-31-I hot-swappable?
A: Yes, it is hot-swappable, which means it can be inserted or removed from a compatible port without the need to power down or restart the switch or device. This feature provides convenience during maintenance or upgrades, minimizing downtime.
Q: Can I get a sample first?
A: We do offer samples before making any production so that the production is up to the buyer's expectations. Samples can be delivered within 5-8 days.
Q: What is the power consumption of it?
A: It has a low power consumption of approximately 1.2W. This energy-efficient design helps reduce operational costs and promotes eco-friendly practices.
Q: How does the transceiver tx power output adjustment work? I noticed that the tx power has a range, but am not sure if it is automatic or adjustable via a switch. Thanks
A: Hello, The description in the datasheet is mainly a range, that is, the actual module TX power in this range. The module TX power according to the use of environmental changes (such as temperature, equipment power supply, etc.) is automatically adjusted and cannot be modified by artificial adjustment.
Q: Is there any damage to the module if it is used for transmission over a short distance of 10 m for an 25G optical module of 10 km? Do I need to use an attenuator?
A: Hello, we need to ensure that the receiving power of the module is not more than the receiver overload power to avoid the module being broken. That's all you need to do. So to get the 25G LR to work at 10 m, you need to add about 3 dB attenuation.
Q: How do I place an order?
A: Please contact our sales representative or send us an inquiry, and we will contact you within 12 hours.
