Product information

Description

TELTONIKA PR4LC21K is an SFP optical transceiver that supports a 1.25 Gb/s data rate and bidirectional (BiDi) operation over a single fibre with a maximum reach of 20 km. The module is intended for use in network equipment with SFP ports and enables single-fiber links by using complementary transmit and receive wavelengths.

Advantages

The NET TRANSCEIVER 1.25GB/S SFP/20KM BIDI PR4LC21K provides compact SFP form factor compatibility, single-fibre BiDi transmission to reduce cabling, and a 20 km reach suitable for metro and access networks. It is interoperable with switches, routers and media converters that accept standard SFP optics.

Suitable for

  • Extending Ethernet links between buildings or sites up to 20 km
  • Connecting switches, routers and media converters with SFP slots
  • Single-fibre installations where reducing fiber count is required

Key specifications

  • Data rate: 1.25 Gb/s
  • Form factor: SFP (Small Form-factor Pluggable)
  • Reach: up to 20 km
  • Operation: BiDi (bidirectional) over single fibre
  • Model / MPN: PR4LC21K
  • Brand: TELTONIKA
  • EAN: 4779051843367

How to use

Insert the SFP transceiver into an SFP port on the switch, router or media converter until it clicks into place. Connect the single-mode fibre patch cable using the appropriate connectors and ensure the complementary BiDi module (opposite wavelength) is installed at the remote end. Verify link status on both devices and configure network settings as required.

Usage recommendations

Use single-mode fibre for links up to 20 km, match the BiDi wavelengths between endpoints, avoid bending the fibre sharply, and ensure equipment supports standard SFP modules. Store and handle the transceiver with dust caps installed when not in use.
