10G SFP+ ZR Long-Distance Optical Technology

The ZR designation is used for extended-reach 10G optical modules. Walsun describes its 10G SFP+ ZR module as an 80km single-mode-fiber solution operating at 1550nm. Walsun 10G SFP+ technical guide

The 1550nm wavelength is well suited to long-distance fiber transmission because it provides low fiber attenuation in the relevant optical window. The module's EML transmitter and APD receiver are also designed for the higher optical budget required by extended-distance links.

80km Single-Mode Fiber Reach

The Walsun 10G SFP+ ZR module supports a maximum specified reach of 80km over single-mode fiber.

This makes it suitable for long-distance network connections such as metro Ethernet, enterprise WAN backbones, telecom aggregation, campus-to-campus links and data center interconnects.

Actual transmission distance depends on fiber attenuation, dispersion, connector losses, splice losses and the complete optical link budget. An 80km-rated transceiver should therefore not be assumed to guarantee 80km on every installed fiber route.

1550nm Optical Wavelength

The module operates at 1550nm, placing it in the long-wavelength optical window commonly used for extended-reach single-mode fiber transmission.

The 1550nm wavelength also makes the module suitable for optical networks where long-distance transmission and high optical power budgets are required.

EML Transmitter and APD Receiver

The HXSX-AL581C/I 80km variant uses an EML laser transmitter and an APD photodetector.

The EML transmitter provides the optical characteristics required for long-distance 10Gbps transmission, while the APD receiver provides higher sensitivity than a conventional PIN receiver, helping the module maintain reliable reception over extended fiber links.

Optical Performance

Walsun specifies a transmit-power range of 0 to +5.0dBm for the 80km module and receiver sensitivity of < -23.0dBm. Walsun official specifications

These values provide the basis for optical link-budget calculations. Before deployment, the complete route should be evaluated for fiber loss, connectors, splices, dispersion and engineering margin.

Duplex LC/UPC Connector

The Walsun 10G SFP+ ZR 80KM uses a duplex LC/UPC optical interface. One fiber carries the transmit signal while the second fiber carries the receive signal.

Duplex LC single-mode cabling is widely deployed in telecom, enterprise and data center optical networks, allowing the module to integrate with standard LC-based fiber infrastructure.

Digital Diagnostic Monitoring

The module supports a digital diagnostic interface. Compatible networking equipment can retrieve operating information from the optical module for network monitoring and troubleshooting.

Depending on host-platform support, DDM/DOM information can include module temperature, supply voltage, laser bias and optical transmit/receive power.

Hot-Pluggable SFP+ Design

The transceiver uses a standard SFP+ footprint and is designed for hot-pluggable installation in compatible networking equipment.

This compact form factor enables high-density deployment in switches, routers, optical transport equipment and network interface devices.

10G SFP+ ZR vs 10GBASE-ER

The ZR module provides substantially greater reach than conventional 10GBASE-ER optics. Walsun describes 10G SFP+ ER as a 40km solution and ZR as an 80km solution. Walsun 10G SFP+ technology guide

10G SFP+ ZR vs 10G SFP+ LR

If the required link is within approximately 10km, an LR optic is generally a more economical choice. For routes approaching tens of kilometers, ER or ZR optics may be more appropriate depending on the required optical budget.

Compatibility

Walsun offers compatible SFP+ modules for major networking vendors and supports customized OEM coding. The company notes that MSA-compatible SFP modules can be programmed for compatibility with different OEM platforms. Walsun SFP+ compatibility information

When purchasing, the exact switch, router, NIC or optical platform should be specified so that the appropriate vendor-coded module can be supplied.
