Product information

Description

The LevelOne SFP-7331 is a compact SFP transceiver module designed for cost-effective, long-reach fiber connections. It supports bi-directional optical transmission over a single fiber core, delivering up to 155 Mbps data rate and enabling point-to-point links up to 20 km when paired with the complementary transceiver. The module uses separate transmit and receive wavelengths to allow simultaneous opposite-direction communication on the same fiber.

Advantages

The SFP-7331 provides economical long-distance connectivity in a small form factor compatible with SFP ports. It supports single-fiber bi-directional operation, reducing fiber cabling requirements, and complies with common industry agreements and monitoring interfaces for interoperability and diagnostics. Low-voltage single +3.3V operation and RoHS lead-free construction ensure broad compatibility and regulatory compliance.

Key specifications

  • Transmit wavelength: 1550 nm (FP LD)
  • Receive wavelength: 1310 nm
  • Data rate: 125–155 Mbps, NRZ
  • Maximum reach: up to 20 km (single fiber core)
  • Power supply: single +3.3 V
  • Connector type: single LC
  • Electrical interface: AC/AC differential
  • Standards compliance: MSA, SFF-8472 (DDM), IEEE 802.3ah 100BASE-BX10-U, FDDI PMD, ATM
  • Environmental: RoHS compliant, lead-free

How to use

Install the SFP-7331 into an SFP slot on a compatible switch, router or media converter, ensuring the module is fully seated. Connect a single-mode LC patch cable to the module’s LC connector and pair the SFP-7331 with the complementary transceiver that uses the opposite wavelengths for bi-directional single-fiber operation. Power on the equipment and verify link and diagnostic status through the host device or SFF-8472 DDM functions.

Recommendations

The SFP-7331 is intended for single-mode fiber links; use it in pairs with the matching SFP module for proper bi-directional operation and verify fiber type and link budget to ensure reliable communication up to 20 km.
