Keep critical optical links aligned with a transceiver designed for demanding transport and access environments. The Finisar FTLF1436W4BTV operates at 1310 nm and supports 24.33 Gbps, 25.78 Gbps, and 10.3 Gbps signaling, making it a practical fit for mixed-rate infrastructures that need consistent performance across multiple link profiles. This module is suited to DFBCPRI and ECPRI deployments where predictable optical behavior matters more than commodity pricing. The 1310 nm wavelength is commonly used for longer-reach single-mode applications, helping teams preserve signal integrity across backbone, aggregation, and radio transport paths. Its SFP+ form factor supports straightforward integration into compatible switches, routers, and transport equipment. For infrastructure teams standardizing on proven optics, this module offers a focused specification set without unnecessary complexity. It is a strong choice when the goal is to keep high-value links stable, reduce compatibility risk, and maintain service continuity in environments where downtime is expensive.
