SFP-lähetin-vastaanotinmoduuli BlueOptics SFP28-25G-LR-PT-BO 25000 Mbit/s 1310 nm

The BlueOptics SFP28-25G-LR-PT-BO is a fiber optic SFP28 transceiver module for single‑mode links supporting data rates up to 25,000 Mbit/s and optical transmission distances up to 10 km. The module operates at a 1310 nm wavelength, uses an LC duplex connector, and is housed in a compact metal casing with a 3.3 V supply. Designed to fit SFP28 interfaces, it is lightweight and suitable for integration in switches, routers and storage systems that accept SFP28 form‑factor modules.

Advantages

The module supports 25GBASE‑LR operation over single‑mode fiber and provides simultaneous transmit and receive paths via an LC duplex connector. Its metal housing offers mechanical robustness and electromagnetic shielding while the standard SFP28 interface enables broad compatibility with devices that follow MSA specifications. Low weight and a small footprint simplify installation and hot‑swap replacement. Where supported by the host device, digital diagnostics (DDM/DOM) provide real‑time monitoring of voltage, laser bias current, optical power and temperature to assist in remote maintenance and troubleshooting.

Suitable for

• 25G Ethernet uplinks and inter‑switch links in data center and campus networks
• High‑speed connections between routers, switches and storage systems
• Longer single‑mode links up to 10 km within metropolitan or enterprise networks
• Environments requiring optical isolation from EMI or fiber‑based backbone connections

How to use

Power down the host port if required by the device documentation, insert the SFP28 module into a compatible SFP28 port following the correct orientation until it latches, and connect LC duplex single‑mode fiber patch cords to the transmit and receive ports. After insertion, verify link status and negotiate speed on the host device according to its configuration procedures. If the host supports DDM/DOM, enable and monitor diagnostic parameters from the management interface to confirm nominal optical power, bias current and temperature.

Recommendations

Use high‑quality single‑mode fiber and LC duplex patch cords for best performance, keep dust caps on the module and fiber ends when not connected, and ensure the host device firmware supports SFP28 modules and any diagnostic features you intend to use. Replace modules if diagnostic values consistently fall outside manufacturer limits.
