  • Product Detail

1.25G CWDM SFP 60KM LC Optical Transceiver is a high-performance optical module designed for extended-reach wavelength division multiplexing applications. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it operates on standardized ITU wavelengths to enable multiple independent data channels over a single fiber strand, significantly enhancing network capacity without additional fiber deployment. 
This transceiver supports 1.25Gbps data rates and achieves an impressive transmission distance of up to 60 kilometers over single-mode fiber, making it particularly suitable for long-haul metropolitan area networks, regional backbone links, and large-scale enterprise network interconnections. Featuring a duplex LC connector interface and hot-pluggable SFP form factor, it ensures seamless integration with existing network infrastructure while maintaining reliable performance across varying environmental conditions. With its superior receiver sensitivity and transmission power, this module provides network operators with a cost-effective and scalable solution for expanding network reach and capacity in demanding CWDM system applications.

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).
