Finisar FTLX1871D3BCL 10GBASE-ZR Connectivity

The FTLX1871D3BCL is designed for 10G Ethernet ZR and 10G Fibre Channel applications. Its multi-rate operation supports 8.5Gbps and 9.95Gbps to 11.3Gbps, allowing the transceiver to be used across several compatible high-speed optical applications.

The module is particularly suited to long-distance backbone, telecommunications, enterprise, and data center links where an 80km optical reach is required.

80KM Single-Mode Fiber Transmission

The transceiver supports links of up to 80km over G.652 single-mode fiber. Its long-reach optical design is intended for extended-distance network connections where standard 10km or 40km SFP+ modules do not provide sufficient reach.

1550nm EML Laser

The module uses a cooled 1550nm EML laser for optical transmission. The laser architecture is designed for long-distance single-mode fiber applications and provides the optical characteristics required for extended-reach 10Gbps links.

SFP+ and Duplex LC Interface

The compact SFP+ form factor provides a hot-pluggable interface for compatible networking equipment. A duplex LC connector provides separate optical transmit and receive paths over the single-mode fiber link.

Digital Diagnostic Monitoring

The FTLX1871D3BCL provides built-in digital diagnostic functions through a 2-wire serial interface in accordance with SFF-8472. This allows compatible host equipment to monitor supported optical operating parameters.
