SFP+ module Extralink EX.35948 10G 1310nm single‑mode LC up to 10 km

Extralink EX.35948 is an SFP+ optical transceiver that supports 10 Gbps data transfer over single‑mode fiber at a 1310 nm wavelength. Equipped with an LC duplex connector and designed for a maximum link distance of up to 10 km, this module is suitable for integration into switches, routers and media converters that accept SFP+ form factor optics. The transceiver is hot‑pluggable and provides a standard optical interface for extending high‑speed links in data center, enterprise and telecom networks.

Advantages

The module provides 10 Gbps transmission over single‑mode fiber with a compact SFP+ form factor, enabling flexible deployment in dense network equipment. Hot‑pluggable design allows insertion and removal without powering down the host device, while the LC duplex connector ensures compatibility with widely used single‑mode patch cables. The transceiver conforms to established optical parameters for reliable long‑distance link performance up to 10 km.

Suitable for

• 10 Gigabit uplinks between switches and routers
• Interconnects in data center and server racks
• Long‑distance links in campus and metropolitan area networks
• Media converters and optical transport equipment with SFP+ ports

Key specifications

• Data rate: 10 Gbps
• Wavelength: 1310 nm
• Fiber type: single‑mode fiber (SMF)
• Connector type: LC duplex
• Maximum reach: up to 10 km (depending on fiber quality and channel conditions)
• Form factor: SFP+
• Hot‑pluggable: yes

How to use

Power down is not required for installation; insert the SFP+ module into a compatible SFP+ port of the switch, router or media converter until it seats firmly and the latch engages. Connect LC duplex single‑mode patch cables to the module, observing correct transmit/receive orientation. Verify link status and speed on the host device management interface or LED indicators. When removing the module, disengage the latch and pull the transceiver straight out to avoid damaging the port. Keep protective dust caps on the optical interfaces when the module is not connected.

Recommendations

Use certified single‑mode fiber and LC duplex connectors to achieve the specified reach. Check compatibility with the host equipment and, if necessary, consult vendor documentation for firmware or platform restrictions. Maintain clean connector endfaces and store unused modules with dust caps to preserve optical performance.
