Advantages of Finisar CA 94089

• Reliability in Harsh Environments: One of the key benefits of CA 94089 is its extended operating temperature range, making it suitable for mission-critical industrial and outdoor installations.
• Plug-and-Play Compatibility: Fully hot-swappable and compatible with most Cisco, HP, Juniper, Huawei, and other networking gear that supports MSA-compliant SFPs.
• Flexible Deployment: Whether used for enterprise networks or in automation control systems, the duplex LC connector allows for easy integration into existing fiber cabling infrastructure.
• RoHS Compliance: Environmentally friendly and safe to deploy in global operations requiring adherence to European directives.

Understanding the LC Duplex Connector

The LC (Lucent Connector) is a compact, high-density fiber optic interface used in both single-mode and multimode applications. It is known for:

• Small form factor and latch mechanism for secure connectivity
• High-precision alignment for minimal signal loss
• Compatibility with duplex and simplex configurations

Industrial Temperature Support (-40°C to +85°C)

Unlike standard commercial SFPs that operate in the 0°C to 70°C range, the Finisar CA 94089 supports extended industrial temperatures. This makes it an excellent choice for use in outdoor cabinets, factory floors, and unconditioned environments where temperature fluctuations are frequent.

Digital Diagnostic Monitoring (DDM)

Some versions of the CA 94089 include support for DDM/DOM (Digital Optical Monitoring) features. These provide real-time data on:

• Module temperature
• Optical output power
• Optical input power
• Laser bias current
• Supply voltage

This enables proactive maintenance and minimizes network downtime.

Compliance and Standards

The CA 94089 adheres to multiple industry standards, making it a safe and reliable addition to your network:

• IEEE 802.3z – 1000Base-SX, 1000Base-LX standards
• SFF-8472 – Digital diagnostics monitoring standard
• RoHS Compliant – Free from hazardous materials
• Class 1 Laser Safety – Eye-safe under all conditions

FAQs – Frequently Asked Questions

• Q: Is CA 94089 compatible with Cisco switches?
  A: Yes, the CA 94089 is MSA-compliant and tested for interoperability with Cisco, Juniper, HP, Arista, and other leading brands. Always verify the vendor’s compatibility list before deployment.
• Q: Can I use this module for single-mode fiber?
  A: No, the CA 94089 is designed specifically for multimode fiber (MMF). Using it on SMF may lead to signal issues or loss.
• Q: What is the max distance supported?
  A: With OM3 multimode fiber, it can typically support up to 2 km at 1310nm, depending on attenuation and power budget.
• Q: Does it support auto-negotiation?
  A: SFP modules operate at fixed speeds (e.g., 1.25Gbps) and do not negotiate like copper Ethernet ports. Make sure both devices match speed and duplex settings.
