PULSAR GBIC-104 SFP-module 1,25 Gbit/s 1310 nm 20 km LC singlemode

The PULSAR GBIC-104 is a high-performance SFP (Small Form-Factor Pluggable) transceiver module designed for Gigabit Ethernet and 1x Fiber Channel applications. It operates at a data rate of 1.25 Gbps over single-mode fiber (SMF) with a wavelength of 1310 nm, supporting distances up to 20 km. The module features a duplex LC connector and is fully MSA compliant (SFF-8472, SFF-8431), ensuring interoperability with a wide range of networking equipment. With built-in Digital Diagnostic Monitoring (DDM/DOM), it provides real-time monitoring of optical parameters for enhanced network management.

Advantages

The GBIC-104 offers reliable, high-speed connectivity for enterprise and data center networks. Its hot-pluggable design allows for easy installation and replacement without disrupting network operations. The module consumes less than 1 W of power, making it energy-efficient. With a robust metal housing, it ensures durability and effective heat dissipation. The commercial-grade operating temperature range (0°C to 70°C) makes it suitable for standard indoor environments.
