2.5G SFP CWDM 80km Single-Mode Fiber Optical Transceiver

The 2.5G SFP CWDM 80km Optical Transceiver is a long-distance optical networking module designed for reliable 2.5G data transmission over single-mode fiber. Supporting data rates up to 2.67Gb/s and transmission distances of up to 80km, it combines a CWDM DFB laser transmitter with a high-sensitivity APD receiver to deliver stable optical performance for extended-reach network links. The module uses a standard SFP hot-pluggable form factor with a Duplex LC optical interface and operates over 9/125μm SMF.

Designed for applications where extended transmission distance and efficient fiber utilization are important, this transceiver can be deployed in CWDM network systems, Ethernet switches, routers, server interfaces, metropolitan area networks, and other long-haul optical communication environments. Its low power consumption and SFF-8472-compliant digital diagnostic monitoring also make it suitable for high-density deployments where link status and operating parameters need to be monitored remotely.

As a B2B optical transceiver manufacturer, FiberMania provides OEM and customization services for 2.5G SFP CWDM optical transceivers. Customized options can include CWDM wavelength selection, equipment-specific EEPROM coding, operating temperature grade, product labeling, housing identification, packaging, and other project-specific requirements.

For network equipment compatibility projects, we can support sample evaluation and compatibility testing before volume production. Customized configurations can also be developed for different transmission distances, wavelengths, network platforms, and deployment environments according to customer specifications.

Q1. Why is an APD receiver used for an 80km optical transceiver?

An APD receiver offers higher optical sensitivity than a conventional PIN receiver, making it well suited to long-distance optical links where the received optical power is relatively low. This helps the module maintain reliable signal reception over extended fiber spans.

Q2. What role does CWDM play in this transceiver?

CWDM allows multiple optical channels at different wavelengths to share the same fiber infrastructure. When deployed as part of a CWDM system, modules using different wavelengths can help increase fiber utilization and expand network capacity without installing additional fiber.

Q3. Does the 80km transmission distance apply to every network installation?

The 80km figure represents the maximum specified reach under suitable optical link conditions. Actual transmission distance depends on factors such as fiber attenuation, connector and splice loss, optical budget, wavelength, and the performance of the equipment at both ends of the link.

Q4. What temperature version should be selected for outdoor or harsh environments?

The appropriate temperature grade depends on the installation environment. Commercial-temperature modules are suitable for controlled indoor environments, while extended- and industrial-temperature versions are better suited to locations exposed to wider temperature variations. The industrial option supports a range down to -40°C.

Q5. Can the CWDM wavelength be customized for a specific network?

Yes. CWDM wavelength selection can be discussed according to the customer’s network architecture and equipment requirements. For larger B2B projects, wavelength configuration, EEPROM coding, labeling, and other module parameters can be customized to support specific deployment requirements.
