TP-Link TL-SM321B-2 SFP module, LC connector

SFP 1G Bi-Directional Single Mode SFP Module - TP-Link TL-SM321B-2
🔗 Bidirectional Gigabit connections over a single fibre, up to 2 km

The TP-Link TL-SM321B-2 is a Wave Division Multiplexing (WDM) 1000BASE-BX SFP module designed for bi-directional single-mode fibre-optic single-wire single-mode transmissions. Paired with the TL-SM321A-2 module, it enables fast and stable data transmission over distances up to 2 km with a single LC simplex connector.

🚀 Gigabit speed - 1.25 Gbps
Delivers consistent performance for mission-critical network applications and point-to-point interconnects.

🔭 S ingle-mode fibre simplex transmission (WDM)
Uses TX: 1310 nm / RX: 1550 nm, enabling full bi-directional communication over a single optical fibre.

📡 Maximum distance: up to 2 km
Ideal for connections on campuses, between buildings or extended networks over short-medium distances.

🔌 Simplex LC connector
Compact and standard design, compatible with most equipment with SFP slots.

🔧 Plug & Play - installation without configuration
Mounts easily into any SFP port without additional technical intervention.
