Description

Overview
The IBM Serial Optical Converter model 23L3336 (part number 21h9872, Cpq# 234458-001) provides a reliable bridge between legacy serial devices and modern fiber optic networks. Designed for high-density data centers and enterprise environments, this converter transforms RS-232/RS-422/RS-485 signals into optical signals for transmission over multimode or single-mode fiber. Its compact metal housing and hot-swap capability make installation quick and minimize downtime.

Key Features

Supports data rates from 9.6 kbps up to 115.2 kbps
Bi-directional conversion with automatic polarity detection
LED status indicators for power, link, and fault conditions
Hot-swap design for seamless replacement without system reboot
Wide operating temperature range from 0 to 70 degrees Celsius
Compatible with standard LC and SC fiber connectors
Built-in loopback test mode for troubleshooting

Technical Specifications

Serial interface: RS-232, RS-422, RS-485
Optical interface: 1310 nm wavelength (single-mode) or 850 nm wavelength (multimode)
Maximum fiber length: up to 10 km for single-mode, up to 550 m for multimode
Power supply: 5 V DC, 500 mA
Dimensions: 2.5 in x 1.0 in x 0.8 in (HxWxD)
Weight: 0.4 lb
Compliance: RoHS, CE, FCC Class B

Applications
The Serial Optical Converter is ideal for connecting legacy industrial controllers, point-of-sale terminals, and security systems to fiber backbone networks. It is frequently used in:

Manufacturing plants that require long-distance serial communication
Hospital environments where electromagnetic interference must be minimized
Data center rack deployments needing high reliability and low latency
Remote monitoring stations in oil and gas fields
University campuses linking older lab equipment to modern network infrastructure

By converting serial data to optical signals, the IBM 23L3336 enhances signal integrity, extends communication distance, and protects against electrical noise, making it a versatile solution for upgrading legacy systems without replacing existing serial devices.
