Frequently Asked Questions

What is the primary application for the Finisar FTLF8538P4BCL SFP28 transceiver? +

The FTLF8538P4BCL is designed primarily for 25G Ethernet applications. It is an ideal solution for high-density data center environments, enterprise server uplinks, and high-performance computing clusters where low-latency, short-reach fiber connectivity is required over multi-mode cabling.

What is the maximum reach of the FTLF8538P4BCL over multi-mode fiber? +

This SFP28 transceiver supports data transmission over OM3 and OM4 multi-mode fiber. Its reach is optimized for short-range deployments, typically up to 70 meters on OM3 or 100 meters on OM4, ensuring robust performance for intra-rack or inter-rack connectivity within standard data center architectures.

Is the Finisar FTLF8538P4BCL compatible with standard SFP28 ports? +

Yes, this module follows the SFP28 multi-source agreement (MSA) standards. It is physically and electrically compatible with standard SFP28 ports found on top-of-rack switches, high-speed network interface cards (NICs), and routers that support 25GBASE-SR specifications.

What type of optical interface does the FTLF8538P4BCL utilize? +

The module utilizes an LC duplex optical interface. This is a common, compact connector type that facilitates high-density port configurations, allowing network administrators to maximize the number of connections in a single switch blade or patch panel without compromising signal integrity.

Does the FTLF8538P4BCL support digital diagnostic monitoring? +

This transceiver includes advanced digital diagnostic monitoring interface (DDMI) capabilities as specified in SFF-8472. This feature allows network administrators to monitor real-time parameters such as optical output power, input power, temperature, laser bias current, and transceiver supply voltage for proactive troubleshooting.

What wavelength does this Finisar SFP28 module operate on? +

The FTLF8538P4BCL operates at an 850nm wavelength. This vertical-cavity surface-emitting laser (VCSEL) technology is specifically tuned for reliable, high-speed data transmission across short-reach multi-mode fiber networks, balancing performance and power efficiency for enterprise environments.

Are there specific power requirements for deploying the FTLF8538P4BCL? +

It operates on a standard 3.3V power supply common to most SFP28 hardware environments. The module is engineered for low power consumption, which helps reduce the thermal load on switches and minimizes overall data center operating costs in dense deployment scenarios.

Can the FTLF8538P4BCL handle legacy 10G speeds? +

While the FTLF8538P4BCL is optimized for 25G Ethernet throughput, backward compatibility depends entirely on the host hardware's capability. If your switch port supports multi-rate configurations and specifically identifies 10GBASE-SR support within its transceiver software profile, the module may perform as expected in legacy links.

How can I obtain a bulk quote for multiple Finisar transceiver units? +
