Cisco SFP-10G-ZR100 Compatible SFP+ 10GBASE-ZR 1550nm 100km DOM Duplex LC/UPC SMF Optical Transceiver Module

Overview

This is a high-performance SFP+ optical transceiver module, engineered to be a fully compatible and cost-effective equivalent to the Cisco SFP-10G-ZR100. It is specifically designed for extreme long-reach applications, conforming to the 10GBASE-ZR standard to deliver reliable 10 Gigabit Ethernet connectivity over distances of up to 100 kilometers using single-mode fiber (SMF).

Utilizing a high-quality 1550nm Externally Modulated Laser (EML) transmitter and a high-sensitivity Avalanche Photodiode (APD) receiver, this module is optimized for performance and signal integrity over extended fiber runs. It is an ideal solution for service provider backhaul, Metro Area Networks (MAN), Data Center Interconnects (DCI), and any enterprise network requiring a stable, high-speed connection between geographically separated sites without the need for costly external amplifiers or repeaters in many scenarios.

• Hot-pluggable SFP+ MSA-compliant form factor for easy installation.
• Low power consumption for enhanced operational efficiency.

Applications

The extended reach of the SFP-10G-ZR100 compatible module makes it essential for large-scale networking:

• Metro and regional Ethernet networks.
• Long-haul point-to-point fiber links.
• Data Center Interconnect (DCI) between separate facilities.
• ISP and telecommunications provider backbone networks.
• Campus networks connecting buildings across a large area.

Specifications

Cross-Platform Compatibility

While programmed for guaranteed compatibility with Cisco equipment, this module’s adherence to MSA (Multi-Source Agreement) standards allows it to function in a wide array of networking hardware from other vendors that do not enforce proprietary coding on their SFP+ ports.

FAQ (Technical & Product Questions)

1. What is 10GBASE-ZR and how does it differ from ER?

10GBASE-ZR is an industry term, not a formal IEEE standard, for 10Gbps optics designed for very long distances, typically 80km or more. The “ZR” stands for “Ze best Reach”. It extends beyond the official 40km reach of 10GBASE-ER by using a more powerful laser and a more sensitive receiver. The SFP-10G-ZR100 pushes this to a 100km link budget.

2. Will I need an optical amplifier for a 100km link with this module?

It depends on the quality and total attenuation of your fiber plant. While the SFP-10G-ZR100 is designed with a link budget to support up to 100km, factors like old fiber, numerous splice points, or dirty connectors can increase signal loss. For links at or near the 100km limit, it is crucial to measure your fiber’s total attenuation. If the loss exceeds the module’s link budget, a pre-amplifier may be required.

3. What kind of fiber patch cable is needed for the SFP-10G-ZR100?

You must use a single-mode fiber (SMF) patch cable, typically OS1 or OS2 grade, with Duplex LC/UPC connectors on both ends to connect to the transceiver.

4. Why is Digital Optical Monitoring (DOM) important for a 100km link?

DOM (also called DDM) is critical for long-haul links because it provides real-time data on key performance metrics like transmit power, receive power, temperature, and voltage. This allows network administrators to proactively monitor the health of the optical link, identify potential degradation in the fiber, and troubleshoot issues before they cause an outage, which is especially important over such long distances.

5. Will using this compatible SFP-10G-ZR100 void my Cisco warranty?

No. Using third-party, MSA-compliant transceivers will not void your network equipment’s warranty. Antitrust laws, such as the Magnuson-Moss Warranty Act in the US, protect consumers’ rights to use third-party hardware. Our modules are built to the same specifications as OEM parts and will not damage your equipment.
