StarTech.com LC Single Mode Fibre Optic Transceiver Module, Full Duplex, 25Gbps

StarTech Fibre Optic Transceiver, 25 Gbps Network Speed, 10 km Maximum Transfer Distance - SFP-25G-LR-S-M-ST

This Fibre optic transceiver is a single-mode module designed to provide high-speed optical links for telecom and data centre environments. It operates over long-reach single-mode Fibre using an LC connection and supports full-duplex transmission, making it suitable for network uplinks and aggregation where consistent optical performance is required.

Features and Benefits:

• 25Gbps nominal rate enabling high-throughput links
  25.78Gbps maximum transfer rate for headroom in bursts
  1310nm Wavelength supports long-distance single-mode transmission
  10km maximum reach for extended campus and metro spans
  LC connector for ubiquitous optical port compatibility
  RoHS-approved construction reducing hazardous substance content

Applications

• Suitable for data centre uplink and switch interconnects
  Ideal for metro and campus Fibre backbone links
  Used for high-speed Ethernet aggregation in automation systems
  Can be used for Fibre upgrades in electrical substation communications

What duplex mode does it use and how does that affect link design?

It operates in full-duplex mode, so separate transmit and receive optical paths are required, enabling simultaneous bidirectional data flow without collision domains.

Which Fibre type is required to achieve rated distances?

Single-mode Fibre is required to reach the specified maximum span and maintain signal integrity at 1310nm.

What connector Interface must my equipment support?

Host ports must accept LC-style optical connectors to mate with the module’s interface.

Are there environmental restrictions implied by the approvals?

The unit meets RoHS requirements, indicating restricted hazardous substance content, but no further environmental performance specifications are provided.
