Key Features of Arista SFP-25G-BD Compatible LINK-PP 25.78G SFP28
Arista SFP-25G-BD Compatible LINK-PP module is a reliable 25G SFP28 BiDi optical transceiver engineered for efficient single-fiber data transmission up to 20km. It integrates a dual-wavelength configuration, a Simplex LC/UPC interface, and Digital Optical Monitoring (DOM) to ensure optimal link stability. This compact module provides a streamlined hardware solution for modern telecom and data center architectures.
This module incorporates a premium 1270nm DFB laser transmitter and a highly sensitive 1330nm PIN receiver. This internal hardware configuration guarantees stable signal transmission and exceptional receiving capabilities over single-mode fiber. The precise alignment of these components ensures minimal signal degradation during bi-directional communication.
SFP-25G-BD: 25 Gbps Connectivity for Core Switch Links
Designed for high-bandwidth environments, this transceiver delivers a dedicated 25 Gbps data rate to accelerate core network layers. It effectively prevents data bottlenecks and ensures rapid throughput between critical switch-to-switch interconnections. This makes it an ideal choice for upgrading bandwidth capacity without altering existing fiber layouts.
SFP-25G-BD Module with 1270nm-TX/1330nm-RX Wavelength
The transceiver utilizes mismatched wavelengths of 1270nm for transmitting and 1330nm for receiving data. This BiDi design allows the module to send and receive signals simultaneously over a single optical strand without any interference. It optimizes spectrum utilization and provides a clean, split-wavelength channel for carrier networks.

Good product, but delayed by local customs The SFP28 transceiver works exactly as described on our switches, but delivery to Italy took two days longer than estimated due to customs processing. Apart from the minor delay, the hardware is fantastic.

Awesome optics, but shipping box arrived slightly crushed The transceivers themselves are top-notch and passed loopback testing with flying colors, but the external white packaging box got banged up during international transit. Better wrap next time please! Product performance is 5/5 though.

Saved our campus fiber backbone deployment We were quoted an astronomical price by our primary vendor for original 25G optics. Found theseSFP28 BiDi modules, checked the specs, and ordered 50 units for our campus network overhaul between buildings. They are performing brilliantly on our 10km single-mode fiber runs, and we saved half our fiber strands for future use! Not a single CRC error or dropped packet after 3 weeks of high-volume testing.
