Description
Product Overview
The EtherWAN SFPGZS20M Hardened Gigabit BiDi SFP Transceiver delivers 1 Gbps 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 optical connections up to 20 kilometers when paired with a compatible reverse-wavelength transceiver. Digital Diagnostic Monitoring (DDM) provides supported optical diagnostics. Its -40°C to +85°C operating temperature range makes the SFPGZS20M suitable for compatible industrial network installations requiring extended fiber reach.
The EtherWAN SFPGZS20M is a hardened Gigabit Ethernet bidirectional SFP optical transceiver for 9/125-micron single-mode fiber. It uses one LC connector and supports rated links up to 20 km. The transmit wavelength is 1550 nm and the receive wavelength is 1310 nm. EtherWAN specifies optical output power of -8 to -2 dBm, receiver sensitivity of -23 dBm, and a nominal 15 dB optical link budget. Digital Diagnostic Monitoring is supported, with an operating temperature range of -40°C to +85°C. The complementary SFPGYS20M uses 1310 nm TX and 1550 nm RX. Compatible Gigabit SFP hosts, appropriate remote optics, and sufficient optical margin are required.
1 Gbps Gigabit Ethernet Connectivity
The SFPGZS20M supports Gigabit Ethernet over compatible SFP network equipment. Its modular optical interface can establish a 1 Gbps link between supported switches and media converters. Verify the host port's supported transceiver type, firmware, and data rate before installation.
Up to 20 km Single-Mode Fiber Reach
The module is rated for connections up to 20 kilometers over 9/125-micron single-mode fiber. Actual reach depends on attenuation, connector and splice losses, remote transceiver characteristics, and adequate optical operating margin.
Single LC Bidirectional Fiber Interface
A simplex LC interface carries transmit and receive signals over one fiber strand using two different optical wavelengths. Unlike a conventional duplex LC transceiver, it does not require separate transmit and receive strands. A compatible complementary BiDi module must be used at the remote endpoint.
1550 nm TX and 1310 nm RX Wavelength Pairing
SFPGZS20M transmits at 1550 nm and receives at 1310 nm. The complementary EtherWAN SFPGYS20M transmits at 1310 nm and receives at 1550 nm. Both modules must satisfy the link's optical power, transmission speed, and host compatibility requirements.
Digital Diagnostic Monitoring Support
Digital Diagnostic Monitoring (DDM) enables compatible network equipment to access optical transceiver diagnostic data. Available readings can help with installation verification and troubleshooting, depending on the host device's management capabilities.
Hardened Operation and 15 dB Optical Budget
The SFPGZS20M operates from -40°C to +85°C. Transmit power of -8 to -2 dBm and receiver sensitivity of -23 dBm provide a nominal 15 dB optical budget. Network engineers should account for cable losses, receiver input limits, and suitable design margin.

What is the EtherWAN SFPGZS20M used for?
The SFPGZS20M is a hardened Gigabit BiDi SFP designed for single-mode fiber links up to 20 km. It uses a single LC connector and complementary optical wavelengths.
How far can SFPGZS20M transmit over fiber?
It supports rated distances up to 20 km over 9/125-micron single-mode fiber. Actual reach depends on optical attenuation, losses, and compatible equipment at both ends.
Which fiber and connector does it use?
It uses single-mode 9/125-micron fiber with a simplex LC connector. Its BiDi design carries transmit and receive traffic over one fiber strand.
Which SFP transceiver pairs with SFPGZS20M?
The complementary EtherWAN SFPGYS20M uses 1310 nm TX and 1550 nm RX, opposite to SFPGZS20M. Both endpoints must have compatible Gigabit hosts.
What are the optical power and link budget specifications?
Transmit power is -8 to -2 dBm, receiver sensitivity is -23 dBm, and nominal optical link budget is 15 dB. Fiber losses and operating margin must be considered.
Does SFPGZS20M support DDM and hardened temperatures?
Yes. DDM is supported, and operating temperature is -40°C to +85°C. Diagnostic access depends on the connected network equipment.
What is the difference between SFPGZS20M and SFPGYS20M?
SFPGZS20M uses 1550 nm TX and 1310 nm RX; SFPGYS20M uses 1310 nm TX and 1550 nm RX. The opposite wavelengths enable compatible single-fiber bidirectional operation.
