SFPGZS20M Hardened Gigabit BiDi SFP Module, 20km

SFPGZS20M Hardened Gigabit Single-Mode BiDi SFP Module

1 Gbps connectivity over one fiber strand, up to 20km reach, single LC connection, and digital diagnostic monitoring.

The EtherWAN SFPGZS20M provides bidirectional Gigabit Ethernet connectivity over a single strand of 9/125µm single-mode fiber. Its single LC connection lets you transmit and receive through one fiber strand, helping conserve available fiber in industrial network installations.

The SFPGZS20M transmits at 1550nm and receives at 1310nm. Pair it with an SFPGYS20M module at the opposite end of the link. Its hardened operating temperature range supports installation in compatible industrial Ethernet switches and media converters.

Key Features

• Gigabit connectivity: Supports 1 Gbps Ethernet fiber links on compatible equipment.
• Single-strand fiber connection: Bidirectional transmission uses one strand of single-mode fiber.
• Up to 20km reach: Designed for extended fiber links, subject to the link’s optical losses.
• Single LC connection: Uses a simplex LC connector with 9/125µm single-mode fiber.
• Complementary wavelength pairing: Transmits at 1550nm and receives at 1310nm, paired with SFPGYS20M at the other end.
• Digital diagnostic monitoring: Includes DDM for supported monitoring functions on compatible equipment.
• Hardened operation: Rated from −40 to 85°C (−40 to 185°F).
• MSA compliant: Follows the Small Form Factor Pluggable Multi-Sourcing Agreement. Confirm support for this module with your equipment manufacturer.

Applications

• Industrial Ethernet connections between buildings or remote facilities.
• Transportation and utility networks using compatible industrial equipment.
• Fiber connections supporting remote IP surveillance networks.
• Network expansion where conserving available fiber strands is important.

Common Questions

Which module should be used at the other end?
Pair the SFPGZS20M with SFPGYS20M. The SFPGZS20M transmits at 1550nm and receives at 1310nm, while SFPGYS20M uses the opposite wavelengths. Two SFPGZS20M modules will not form the intended link.

Does this module need one or two fiber strands?
It uses one strand of 9/125µm single-mode fiber with an LC connection. Different wavelengths carry traffic in each direction through the same strand.

Will this module work in any SFP port?
Confirm that the equipment supports a 1 Gbps BiDi SFP module with these specifications. The SFP form factor and MSA compliance alone do not guarantee compatibility with every switch or media converter.
