SFP (mini-GBIC) transceiver module HP SFPC2F1GS1320 — singlemode 1310 nm, LC duplex, 1.25 Gbps, up to 20 km

The HP SFP (mini-GBIC) transceiver module SFPC2F1GS1320 is a hot-pluggable optical module for singlemode fiber links operating at a 1310 nm wavelength. It provides a 1.25 Gbps data rate over LC duplex connectors and supports link distances up to 20 km, making it suitable for uplinks, aggregation, and long-reach connections in enterprise and service provider networks. The module follows SFP form-factor conventions for compatibility with a wide range of switches and routers that accept SFP transceivers.

Advantages

This SFP transceiver offers hot-pluggable installation, standardized LC duplex interfaces and a singlemode 1310 nm optical design for predictable performance over extended distances. The 1.25 Gbps data rate and up to 20 km reach support common gigabit network topologies while minimizing the need for intermediate repeaters. Its compact SFP form factor conserves port density on networking equipment and facilitates straightforward replacement or upgrades without powering down connected devices.

Suitable for

• Fiber uplinks between switches and routers in enterprise LANs
• Point-to-point singlemode links up to 20 km
• Aggregation and access connections in carrier and data centre networks
• Replacing or expanding SFP ports on compatible network equipment

Key specifications

• Optical mode: singlemode
• Wavelength: 1310 nm
• Connector type: LC duplex
• Data rate: 1.25 Gbps (Gigabit Ethernet/SONET/SDH compatible)
• Maximum link distance: up to 20 km (depending on fiber and loss budget)
• Form factor: SFP (mini-GBIC), hot-pluggable

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or optical interface module while the host device is powered on to take advantage of hot-pluggable capability. Secure an LC duplex patch cable between the module and the remote transceiver, observing proper polarity for transmit and receive fibers. Verify link status and interface settings on the host device, configure speed/duplex or auto-negotiation as required, and monitor optical parameters where supported by the equipment.

Usage recommendations

Use singlemode LC duplex fiber with appropriate attenuation and connectors rated for 1310 nm; verify fiber loss budget for distances approaching 20 km. Handle the transceiver and fiber connectors using ESD-safe practices and keep protective dust caps on connectors when not in use. Confirm compatibility with the host device's SFP slot and, if necessary, ensure firmware or vendor settings allow use of third-party transceivers.
