Frequently Asked Questions
What is a 50GBASE-ER BIDI SFP56 transceiver used for?
The 50GBASE-ER BIDI SFP56 is used for high-speed, long-distance optical networking in data centers, campus networks, and carrier environments. It enables 50 Gbps bidirectional communication over single-mode fiber up to 40 kilometers, reducing cabling complexity by transmitting and receiving on a single fiber strand.
How does bidirectional (BIDI) technology work in this SFP56 module?
Bidirectional technology uses wavelength division multiplexing (WDM) to send and receive data simultaneously over one fiber. The 50GBASE-ER BIDI SFP56 transmits at 1314 nm and receives at 1289 nm, allowing full-duplex communication without requiring separate transmit and receive fibers.
Is the ENET 50GBASE-ER BIDI SFP56 compatible with standard network equipment?
Yes, this SFP56 transceiver is MSA-compliant, meaning it meets industry-standard specifications for SFP56 form factor modules. It works with any network switch, router, or optical interface that supports standard SFP56 ports and 50GBASE-ER protocols.
What is the maximum transmission distance for this 50GBASE-ER BIDI module?
The ENET 50GBASE-ER BIDI SFP56 supports transmission distances up to 40 kilometers on single-mode fiber (SMF), making it suitable for metropolitan area networks and long-distance campus interconnects without requiring signal regeneration.
