Product information

Description

The LevelOne 1.25Gbps Single-mode SFP Transceiver (GVT-0301) enables fiber Gigabit connections for data and telecommunications. It supports a 1.25 Gbps (1250 Mbit/s) data rate over single-mode fiber at 1310 nm and is specified for link distances up to 10 km. The module uses a duplex LC connector and is compatible with devices that accept SFP/mini-GBIC modules, including LevelOne switches and certain GSW-2453 and GVT-4000 series products. The transceiver operates from a single 3.3 V power supply and meets IEEE 802.3z Gigabit Ethernet requirements.

Advantages

This SFP transceiver adds 1000Base-LX capability to compatible switches, supports hot-swappable installation, and provides TTL signal detection. Its differential LVPECL input/output design supports reliable high-speed signaling while the single-mode 1310 nm optics enable up to 10 km reach. The small form-factor SFP design ensures compactness and interoperability with standard mini-GBIC ports.

Suitable for

Extending switch-to-switch connections up to 10 km over single-mode fiber
High-speed I/O and file transfer between networked devices
Distributed multiprocessing and campus/backbone links
Channel extension and data storage network links

Key specifications

Model: LevelOne GVT-0301 (MPN: GVT-0301NEUEVERSION, EAN: 4015867224397)
Data rate: 1250 Mbit/s (1.25 Gbps)
Wavelength: 1310 nm
Maximum reach: up to 10 km (single-mode fiber)
Connector: Duplex LC
Interface: SFP / mini-GBIC, 1000Base-LX, IEEE 802.3z compliant
Power supply: single 3.3 V
Signal detect: TTL

How to use

Insert the SFP transceiver into an SFP/mini-GBIC port on a compatible switch or module while the device is powered on or off; the module is hot-swappable. Connect duplex single-mode fiber cables with LC connectors to the transceiver, ensuring correct Tx/Rx orientation. Verify link status via the host device and check the TTL signal detect indicator. Configure the connected network equipment as required for 1000Base-LX operation.

Usage recommendations

Use single-mode fiber with LC duplex connectors and observe correct polarity. For reliable links up to 10 km, ensure fiber quality and connector cleanliness. Confirm compatibility with the host device’s SFP support list before deployment and operate the transceiver within the specified 3.3 V supply and ambient conditions.
