Description
Product Overview
The EtherWAN SFPMYS20M Hardened 100BASE BiDi SFP Fiber 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 1310 nm and receives at 1550 nm, supporting fiber links up to 20 kilometers when paired with a compatible reverse-wavelength transceiver. Digital Diagnostic Monitoring (DDM) enables supported optical diagnostic readings. Its hardened -40°C to +85°C operating temperature range makes the SFPMYS20M suitable for compatible industrial networks requiring extended fiber reach.
The EtherWAN SFPMYS20M is a hardened 100BASE bidirectional SFP transceiver for 100 Mbps Ethernet communication over 9/125-micron single-mode fiber. It has a simplex LC connector and supports distances up to 20 km. The module transmits at 1310 nm and receives at 1550 nm. EtherWAN specifies optical output power from -14 to -8 dBm, receiver sensitivity of -32 dBm, and a nominal 18 dB optical power budget. DDM is supported and operating temperature is -40°C to +85°C. Its complementary SFPMZS20M transmits at 1550 nm and receives at 1310 nm. Compatible 100BASE SFP hosts and suitable fiber loss margins are required.
100 Mbps Fast Ethernet Connectivity
The SFPMYS20M supports 100BASE Fast Ethernet transmission through compatible SFP-equipped network devices. It is designed for 100 Mbps applications rather than Gigabit or 10 Gigabit Ethernet. Verify the supported link speed and transceiver compatibility of the host switch or media converter.
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 reach depends on fiber attenuation, connectors, splices, paired optics, and suitable margin within the available optical power budget.
Single LC Bidirectional Fiber Interface
The simplex LC connector carries both transmit and receive communication over one fiber strand using different optical wavelengths. This design eliminates the need for separate transmit and receive fibers, provided a compatible complementary transceiver is installed at the remote endpoint.
1310 nm TX and 1550 nm RX Wavelengths
SFPMYS20M transmits at 1310 nm and receives at 1550 nm. Its complementary EtherWAN SFPMZS20M uses 1550 nm TX and 1310 nm RX. Both modules must satisfy the same transmission-speed requirements and be supported by their respective host devices.
Digital Diagnostic Monitoring Support
Digital Diagnostic Monitoring (DDM) provides supported transceiver diagnostics through compatible networking equipment. Depending on host capabilities, these readings can assist technicians in evaluating optical link conditions and troubleshooting connectivity problems.
Hardened Operation with an 18 dB Link Budget
The module operates from -40°C to +85°C and specifies optical output power from -14 to -8 dBm with receiver sensitivity of -32 dBm. These values correspond to a nominal 18 dB optical power budget. Engineers should consider fiber attenuation, receiver power limits, and appropriate operating margin.

What is the EtherWAN SFPMYS20M used for?
It is a hardened 100 Mbps Fast Ethernet BiDi SFP designed for 20 km single-mode fiber links. It uses a simplex LC connector and complementary optical wavelengths.
Does SFPMYS20M support Gigabit Ethernet?
No. It operates at 100 Mbps Fast Ethernet rather than 1 Gbps. The host must support compatible 100BASE SFP operation.
How far can SFPMYS20M transmit over fiber?
EtherWAN rates the module for up to 20 km over 9/125-micron single-mode fiber. Actual reach depends on optical attenuation and available power margin.
Which transceiver pairs with SFPMYS20M?
The complementary EtherWAN SFPMZS20M transmits at 1550 nm and receives at 1310 nm. The SFPMYS20M uses the opposite wavelengths.
What are the optical output power and link budget?
Transmit power is -14 to -8 dBm and receiver sensitivity is -32 dBm, giving a nominal 18 dB optical power budget.
Does SFPMYS20M support DDM and hardened temperatures?
Yes. DDM is supported and the module operates from -40°C to +85°C. Available diagnostics depend on host support.
What is the difference between SFPMYS20M and SFPMZS20M?
SFPMYS20M uses 1310 nm TX / 1550 nm RX; SFPMZS20M uses 1550 nm TX / 1310 nm RX. Their opposite wavelengths allow compatible single-fiber bidirectional communication.
