Description
Product Overview
The EtherWAN SFPMZS20M Hardened 100BASE BiDi SFP Transceiver provides 100 Mbps Fast Ethernet connectivity over a single strand of 9/125-micron single-mode fiber. Featuring a simplex LC connector, the module transmits at 1550 nm and receives at 1310 nm, supporting fiber connections up to 20 kilometers when paired with a compatible reverse-wavelength transceiver. Digital Diagnostic Monitoring (DDM) enables supported networking equipment to access optical diagnostic information. With a hardened operating temperature range of -40°C to +85°C, the SFPMZS20M is suitable for compatible industrial Ethernet installations requiring extended fiber connectivity.
The EtherWAN SFPMZS20M is a hardened 100BASE Small Form-factor Pluggable optical transceiver for 100 Mbps Fast Ethernet communication over single-mode fiber. EtherWAN specifies a simplex LC connector, 9/125-micron fiber, 20 km maximum rated distance, 1550 nm transmit wavelength, and 1310 nm receive wavelength. Optical transmit power is -14 to -8 dBm, with receiver sensitivity of -32 dBm and a nominal 18 dB optical link budget. DDM is supported and operating temperature ranges from -40°C to +85°C. The complementary SFPMYS20M uses 1310 nm TX and 1550 nm RX. Successful operation requires compatible 100BASE SFP host equipment, complementary wavelengths, and suitable fiber attenuation.
100 Mbps Fast Ethernet Connectivity
The SFPMZS20M supports 100BASE Fast Ethernet through compatible SFP-equipped networking devices. It is designed for 100 Mbps operation rather than Gigabit or 10 Gigabit Ethernet. Verify that the host switch or media converter explicitly supports 100BASE optical SFP modules.
Up to 20 km Single-Mode Fiber Reach
EtherWAN rates this module for distances up to 20 kilometers over 9/125-micron single-mode fiber. Actual transmission distance depends on fiber attenuation, connector and splice losses, the remote transceiver, and adequate operating margin within the available optical power budget.
Single LC Bidirectional Fiber Interface
The simplex LC connector transmits and receives optical signals over one fiber strand using separate wavelengths. Unlike duplex LC modules, it does not require two dedicated fiber strands. A compatible reverse-wavelength transceiver is required at the opposite endpoint.
1550 nm TX and 1310 nm RX Wavelength Pairing
SFPMZS20M transmits at 1550 nm and receives at 1310 nm. Its complementary EtherWAN SFPMYS20M transmits at 1310 nm and receives at 1550 nm. Both modules must meet the required host-interface, transmission-speed, and optical power specifications.
Digital Diagnostic Monitoring Support
Digital Diagnostic Monitoring provides supported optical transceiver diagnostic information for compatible networking equipment. Available readings can help technicians evaluate link operation and investigate connectivity problems, depending on host management capabilities.
Hardened Operation with an 18 dB Optical Budget
The module operates from -40°C to +85°C, with optical transmit power from -14 to -8 dBm and receiver sensitivity of -32 dBm. These values provide a nominal 18 dB optical budget. Engineers should account for actual link losses, receiver input limits, and suitable operating margin.

What is the EtherWAN SFPMZS20M used for?
The SFPMZS20M is a hardened 100 Mbps Fast Ethernet BiDi SFP transceiver for single-mode fiber. It uses a simplex LC connector and provides rated connections up to 20 km with compatible equipment.
Does SFPMZS20M support Gigabit Ethernet?
No. It is specified for 100 Mbps Fast Ethernet, not 1 Gbps. The connected switch or media converter must support 100BASE SFP operation and this optical module.
How far can this transceiver transmit over fiber?
EtherWAN rates it for distances up to 20 km over 9/125-micron single-mode fiber. Actual reach depends on attenuation, connectors, splices, and optical operating margin.
Which transceiver pairs with SFPMZS20M?
EtherWAN SFPMYS20M provides the complementary wavelengths: 1310 nm TX and 1550 nm RX. Both modules require compatible host equipment and a suitable single-mode fiber link.
What are its optical power specifications?
Transmit power is -14 to -8 dBm and receiver sensitivity is -32 dBm, corresponding to a nominal 18 dB optical budget. Allow for fiber losses and engineering margin.
Does it support DDM and hardened temperatures?
Yes. DDM is supported and the module operates from -40°C to +85°C. Available diagnostics depend on the host device and its management interface.
What is the difference between SFPMZS20M and SFPMYS20M?
SFPMZS20M uses 1550 nm TX and 1310 nm RX, while SFPMYS20M uses 1310 nm TX and 1550 nm RX. Their complementary wavelength arrangements allow compatible single-fiber bidirectional operation.
