## Summary description

The LevelOne 1.25Gbps Multi-mode SFP Transceiver is designed for high-speed data transfer over fiber optic connections. With a maximum data transfer rate of 1250 Mbit/s and a range of up to 550m at 850nm, it ensures reliable performance. This SFP transceiver is compatible with GSW-2453 and GVT-4000 products. It features a compact design with dimensions of 13.4mm width, 56.6mm depth, and 8.4mm height, making it easy to integrate into various systems. Certified under Class 1 Laser standards, it operates at an input voltage of 3.5V and a maximum current of 0.3A.

## Long description

The LevelOne GVT-0300 SFP fiber optic transceiver provides full-duplex Gigabit Ethernet connectivity over multi-mode fiber at distances up to 550 meters. It supports 1.25 Gb/s data rate at a nominal wavelength of 850 nm, is MSA-compliant for cross-vendor compatibility, and uses a click-and-latch duplex LC connector. The module is hot-pluggable and intended for short-range network links in switches, converters and similar equipment that accept SFP (Mini-GBIC) transceivers.
Advantages
The GVT-0300 is compliant with IEEE 802.3z and the SFP MSA, ensuring interoperability with compatible network equipment. It offers a compact, hot-pluggable form factor, low-voltage single 3.3 V supply, TTL signal detect indicator and EEPROM with serial ID for system identification. The duplex LC connector provides a secure physical connection for multimode fiber links up to 550 m.
Suitable for
Short-range Gigabit Ethernet links over multimode fiber (up to 550 m)
Switch-to-switch and switch-to-converter connections
High-speed I/O and file transfer links within data centers
Bus extension and channel extension in storage or distributed systems
Key specifications
Brand: LEVELONE, Model: GVT-0300
Interface type: SFP (Small Form-Factor Pluggable)
Data rate: 1.25 Gb/s (1250 Mbit/s)
Wavelength: 850 nm (nominal)
Fiber type: Multi-mode fiber
Maximum link distance: up to 550 m
Connector: Duplex LC (click-and-latch)
Standards: IEEE 802.3z, SFP MSA compliant
Power: single 3.3 V supply; input voltage listed as 3.5 V in product data, max current 0.3 A
Safety: Class 1 Laser
How to use
Insert the SFP transceiver into a compatible SFP slot on a switch, converter or other networking device until the click-and-latch secures the module. Connect duplex multimode fiber patch cords to the LC connector. Ensure both ends of the link use compatible transceivers and matching fiber type. Observe system power requirements and verify the device recognizes the module via the TTL signal detect indicator or host EEPROM ID.
Usage recommendations
Use multimode fiber cabling rated for Gigabit-Ethernet and keep link distances within 550 m to maintain signal integrity. Avoid forcing the LC connector during insertion, and handle the transceiver by its housing to prevent contamination of optical interfaces. Match transceiver wavelength and multimode fiber specifications at both ends for reliable operation.
