Wi-Tek - WI-SFP21L-550-I - Industrial SFP Module

Product Overview

WI-SFP21L-550-I is an industrial 1.25 Gbps SFP optical transceiver designed for short-distance network connections over multimode fiber. It uses a duplex LC connector, operates at 850 nm, supports links up to 550 m, and includes Digital Diagnostic Monitoring for reliable operation from -40°C to 85°C.

Key Configuration

Model: WI-SFP21L-550-I | Data Rate: 1.25 Gbps | Maximum Cable Length: 550 m | Fiber: Multimode | Connector: Duplex LC | Wavelength: 850 nm | Power Supply: 3.3 V | Power Consumption: 1 W max

Key Features

• · Supports 1.25 Gbps data transmission
• · Extends multimode fiber links up to 550 m
• · Uses a duplex LC optical connector
• · Operates at an 850 nm wavelength
• · Uses a VCSEL transmitter and PIN/TIA receiver
• · Provides receiver sensitivity below -18 dBm
• · Supports Digital Diagnostic Monitoring (DDM)
• · Uses a 3.3 V power supply with consumption up to 1 W
• · Supports SFP MSA, MSA SFF-8472, and IEEE 802.3Z compatibility

Technical Context

The transceiver converts electrical network data into optical signals for transmission over multimode fiber and converts received optical signals back to electrical data. Its 850 nm wavelength, 550 m reach, and DDM support provide a practical fiber uplink solution with monitoring of key operating parameters in compatible SFP equipment.

Installation Notes

Insert the module into a compatible SFP slot and connect the duplex LC fiber pair to the optical link. Use multimode fiber and ensure that the remote transceiver or module matches the 1.25 Gbps, 850 nm, 550 m optical specification. The module is hot-pluggable and supports plug-and-play operation without additional configuration.
