SFP28 kuitu-lähetin-vastaanotin Lancom Systems SFP-SR-LC25, 25 Gbit/s, LC, ruostumaton teräs, Bulk 10

SFP-SR-LC25 is a Lancom Systems SFP28 fiber optic transceiver module in SFP form factor with an LC duplex interface, designed for short-reach multimode fiber links at up to 25 Gbit/s. Housed in stainless steel and supplied in a bulk pack of 10, each transceiver is intended for uplinks and aggregation in data center, campus and enterprise network environments. The module supports operation in devices with SFP28-compatible ports, enabling flexible fiber connections for switches, routers and firewalls.

Advantages

The stainless-steel housing provides mechanical robustness and reliable thermal performance in typical networking racks and chassis. Support for 25 Gbit/s link rates and compatibility with multimode fiber make the module suitable for short-distance high-speed links. The LC duplex connector and SFP28 form factor allow hot-swappable installation in compatible ports without interrupting system operation, while the bulk packaging of 10 units simplifies deployment for multiple ports or spare inventory.

Suitable for

• Short-reach 25 Gigabit Ethernet uplinks and aggregation within data centers
• Campus network connections between wiring closets and aggregation switches
• Enterprise network uplinks for access switches and firewalls with SFP28 ports
• Multimode fiber segments where distances are within short-reach limits

Key specifications

• Interface: LC duplex fiber connector
• Form factor: SFP28 (hot-swappable)
• Nominal link speed: up to 25 Gbit/s
• Optical wavelength: 850 nm
• Fiber type supported: multimode fiber (50 µm / 125 µm)
• Typical maximum reach on multimode fiber: up to 100 m
• Housing material: stainless steel
• Packaging: bulk pack of 10 units

How to use

Install the SFP-SR-LC25 into an SFP28-compatible port on a switch, router or firewall while the device is powered according to the host documentation; the module is designed to be hot-swappable but follow your system vendor recommendations for live swaps. Terminate multimode fiber with LC duplex connectors and verify correct polarity before insertion. After insertion, confirm link status and negotiate the desired link speed in the host device management interface. Use appropriate fiber cleaning procedures to maintain optical performance.

Recommendations

Use OM3/OM4 multimode fiber where available to ensure reliable 25 Gbit/s short-reach performance and adhere to the maximum recommended segment length (up to 100 m). Keep spare transceivers from the bulk pack for rapid replacement and ensure connectors are clean and protected during installation to prevent signal loss.
