Frequently Asked Questions
What is a 25GBASE-ER BIDI SFP28 transceiver used for?
The 25GBASE-ER BIDI SFP28 is used for long-distance, single-fiber optical connectivity in data centers, campus networks, and carrier environments. The bidirectional design reduces fiber infrastructure costs by enabling full-duplex communication over one fiber strand instead of two, making it ideal for fiber-constrained deployments.
How does bidirectional (BIDI) technology work?
Bidirectional SFP28 modules use wavelength division multiplexing (WDM) to transmit and receive data simultaneously on a single fiber. The ENET module transmits at 1270nm while receiving at 1310nm, allowing two-way communication without requiring separate transmit and receive fibers.
What is the maximum transmission distance for this 25G SFP28 module?
This 25GBASE-ER BIDI transceiver supports distances up to 40km over single-mode fiber, making it suitable for extended-reach campus interconnects and metropolitan area network (MAN) applications.
Is the ENET 25GBASE-ER BIDI SFP28 compatible with my network equipment?
Yes, the ENET module is MSA-compliant and hot-pluggable, working with any 25G SFP28-enabled network switch, router, or adapter. Verify your equipment supports SFP28 form factor and 25GBASE-ER protocol before installation.
