With a typical power consumption of 1.5 W, it is designed for high-speed data transmission in networking applications.

## Long description

The Extralink EX.16538 SFP transceiver is an SFP28 fiber optic module engineered for high-speed 25G links. It supports a maximum data transfer rate of 25780 Mbit/s at a wavelength of 1310 nm, requiring a 3.3 V supply and consuming typically 1.5 W. Designed for single-mode optical links, the module offers a cost-effective option for network upgrades where compact hot-pluggable SFP28 form factor and low power consumption are required.
Advantages
This SFP28 transceiver delivers near-25G performance with a compact SFP form factor, allowing easy installation into compatible switches and routers. Low power usage (around 1.5 W) and an extended operating temperature range from 0°C to 70°C make it suitable for standard data-center and enterprise environments. The design targets economical 25 Gbps single-band optical connections while maintaining compliance with relevant IEEE gigabit Ethernet guidelines.
Suitable for
 25G optical uplinks between switches and aggregation devices
 Data center server-to-switch connections requiring SFP28
 Enterprise and campus backbone links up to typical single-mode distances
 Network equipment upgrades where low power and compact modules are needed
Key specifications

How to use
Install the Extralink EX.16538 by inserting the SFP28 module into a compatible SFP/SFP28 slot on a switch, router or transceiver cage while the host device is powered according to the vendor’s hot-swap policy. Connect appropriate single-mode fiber cables terminated with matching connectors. Verify link status and speed in the host device management interface and ensure that both ends use compatible modules and matching transmission parameters (wavelength, data rate).
Usage recommendations
Use this module in equipment that supports SFP28 and 25G rates. For reliable performance, pair with single-mode fiber and maintain clean connector endfaces. Confirm firmware or driver compatibility on the host device and monitor module temperature and power within specified ranges.
