Ernitec Small Form Factor Pluggable (SFP) transceiver data link up to 550m in 50/125um multi mode fiber

The Ernitec ELECTRA-S-SFP-S is a Small Form Factor Pluggable (SFP) fiber-optic transceiver module designed for high-speed data transmission over multimode fiber. The module complies with SFP MSA specifications and integrates a VCSEL laser, PIN photodetector, LD driver, limiting amplifier and digital diagnostic monitor. It supports transmission over 50/125 µm multimode fiber up to 550 m and features a metallic housing for durability and professional appearance.

Advantages

The SFP form factor provides hot-pluggable flexibility and broad compatibility with SFP ports. Integrated digital diagnostics allow monitoring of optical and electrical parameters. The metallic finish improves mechanical protection and thermal dissipation, while the combination of VCSEL and PIN photodetector offers stable multimode optical performance for short- to mid-range links.

Suitable for

• Campus and building backbone links
• Switch-to-switch or switch-to-server connections
• Industrial and commercial network equipment with SFP ports
• Multimode fiber installations using 50/125 µm cable

Key specifications

• Interface type: SFP
• Fiber type: Multimode fiber (50/125 µm)
• Maximum link distance: up to 550 m (on 50/125 µm MMF)
• Laser type: VCSEL
• Diagnostic: Digital diagnostic monitor supported
• Housing colour: Metallic

How to use

Insert the ELECTRA-S-SFP-S module into a compatible SFP port on switches, routers or media converters while the host device is powered according to the equipment manual. Connect the multimode fiber (50/125 µm) using appropriate LC or specified connector types, ensure proper fiber polarity and secure connections. Verify link and diagnostics via the host device’s interface and monitor reported parameters if needed.

Recommendations

Use within the specified multimode fiber type (50/125 µm) and keep fiber connectors clean. Observe ESD precautions during handling and consult the host equipment compatibility list to ensure full operational support of digital diagnostics and SFP parameters.
