FAQ:


Q1: What is a 1.25G SFP transceiver?‌

A1: 1.25G SFP (Small Form-factor Pluggable) is a compact, hot-swappable optic module supporting 1.25Gbps speeds for fiber or copper networks, commonly used in Gigabit Ethernet and Fiber Channel applications.

Q2: What are the typical applications of 1.25G SFP?‌
A2: Gigabit Ethernet (1000BASE-SX/LX/ZX)‌
Fiber Channel (1G/2G/4G)‌
SDH/SONET networks‌

Q3: What is the maximum distance for 1.25G SFP LX?‌
A3: The ‌1000BASE-LX‌ variant supports up to ‌10km‌ over single-mode fiber (SMF), while ‌1000BASE-SX‌ reaches ‌550m‌ over multimode fiber (MMF).

Q4: What wavelengths do 1.25G SFP modules use?‌
A4: SX‌: 850nm (MMF); LX/ZX‌: 1310nm/1550nm (SMF)

Q5: How does a BIDI SFP differ from a standard SFP?‌
A5: Standard SFPs require ‌two fibers‌ (one for TX, one for RX), while BIDI SFPs use ‌one fiber‌ with wavelength-division duplexing (WDM).

Q6: How far can a 1.25G SFP ZX module transmit data?‌
A6: The ‌ZX variant‌ supports extended distances up to ‌80km over single-mode fiber‌, ideal for long-haul applications like telecom backbones.

Q7: Are 1.25G SFP modules compatible with industrial temperature ranges?‌
A7: Yes, many industrial-grade modules operate in ‌extreme temperatures from -40°C to 85°C‌, ensuring reliability in harsh environments like outdoor networks.

Q8: What is the role of Digital Diagnostics Monitoring (DDM/DOM) in 1.25G SFP?‌
A8: DDM/DOM provides real-time tracking of parameters like temperature and optical power, enabling proactive maintenance and fault detection for network stability.

Q9: Can 1.25G SFP modules connect to CWDM or DWDM systems?‌
A9: Yes, specialized ‌CWDM and DWDM variants‌ exist for wavelength division multiplexing, allowing efficient bandwidth usage in metro or data center networks.

Q10: Why choose BIDI over standard SFP for FTTH?‌
A10: BIDI SFPs ‌halve fiber usage‌, reducing infrastructure costs in passive optical networks (PON).
