Hello, everyone working in networking, system integration, and telecommunications operations and maintenance!

Friends often ask me: For remote base stations, field security, and the renovation of old government and enterprise dedicated lines, the business needs to run 25G and the distance needs to be 80km, but we only have single-core optical fiber left and do not want to lay new lines, is there a stable, reliable and cost-effective solution?

To address the challenges of "long distance + fiber shortage + cost control," today we'd like to highlight ETU-LINK self-developed blockbuster product: 25G SFP28 BIDI ZR 80km Optical Module, a high-performance, cost-effective "lifesaver" for long-distance networking.

I. Product Overview

The 25G SFP28 BIDI ZR 80km is an ultra-long-distance optical module independently developed by ETU-Link Technology Co., Ltd.. It adopts a standard SFP28 hot-swappable form factor and a single LC connector design, making it plug-and-play and compatible with various mainstream communication equipment. The product strictly complies with IEEE 802.3cc and EU Directive 2015/863/EU, and meets RoHS environmental standards.

II. Key Product Features

1.Bidirectional transmission over a single fiber for high efficiency and cost savings

Using single-core optical fiber enables bidirectional transmission and reception, saving 50% of optical fiber resources. No new optical cable construction is required, revitalizing existing links and significantly reducing network construction costs.

2.Professional long-distance architecture for stable transmission

Equipped with a professional long-distance architecture of EML transmitter + integrated SOA optical amplifier + PIN TIA receiver , it can achieve stable 80km transmission without repeaters on conventional G.652 single-mode fiber without additional dispersion compensation. With DDM real-time link diagnosis, operation and maintenance are efficient and convenient.

3.Dual-temperature support for universal compatibility across all scenarios

There are two versions, one for commercial use and one for industrial use. The industrial version supports an ultra-wide operating temperature range of -40℃ to 85℃, making it suitable for extreme high and low temperatures and temperature fluctuations in the wild, and adaptable to all complex indoor and outdoor scenarios.

4.Standard wavelength pairing for low error rates and high capacity

It adopts industry-standard reverse pairing wavelengths (Tx 1295nm/Rx1309nm for A-end and Tx 1309nm/Rx 1295nm for B-end), which are highly compatible and interoperable, avoid the failure of compatibility with niche wavelengths, and effectively reduce the cost of trial and error in project selection.

III. Diverse Application Scenarios

1. Adaptable to backhaul from remote base stations in mountainous areas and rural towns.

2. Meets the networking needs of enterprises across multiple parks and branches for point-to-point networking.

3. Adaptable to complex outdoor scenarios such as highways, mining areas, and forest areas.

4. Metropolitan Area Network Edge Expansion

5. Supports point-to-point interconnection between data centers within the same city within 80km.

Product Summary

In long-distance networking scenarios, dual-fiber modules offer stable performance but high fiber consumption costs, while ordinary short-distance modules are cheaper but have limited range and are unstable. The 25G BIDI ZR 80km optical module strikes a perfect balance, offering four core advantages: cost-saving single-fiber operation, low-power and stable transmission, global compatibility, and easy maintenance. It perfectly addresses the three major pain points of long-distance networking: fiber shortage, long distance, and high cost.

With fiber optic resources scarce and the need for long-distance transmission over 80km required, this is the perfect choice!
