EXTRALINK SFP 1.25G WDM 1310/1550 nm SM 20 km LC DOM – Pair (EX.6204)

EXTRALINK SFP 1.25G WDM 1310/1550 nm SM 20 km LC DOM – Pair (EX.6204)

The EXTRALINK SFP 1.25G WDM set is an efficient pair of single-mode BiDi optical transceivers designed for data transmission rates up to 1.25 Gbps over distances of up to 20 km using a single SMF fiber. The modules operate on alternating wavelengths: transmitter (Tx) at 1310 nm and receiver (Rx) at 1550 nm, enabling bidirectional communication over one fiber strand.

Extralink SFP transceivers offer high performance and reliability while remaining cost-effective. Each module consists of an FP laser transmitter, a PIN photodiode with TIA preamplifier, and an MCU control unit. DOM/DDM support allows real-time monitoring of operating parameters. All modules comply with Class I laser safety requirements.

Applications:
SFP 1.25G optical modules are suitable for Gigabit Ethernet networks, Fibre Channel, switch-to-switch links, router-to-server interfaces, and other optical transmission systems.
