Finisar FTLC3321F3NL(CFP2-200G coherent) is a 200G coherent optical module designed for long-distance transmission.
It adopts CFP2 packaging and advanced digital coherent technology. Here is its detailed product description and technical analysis:
1. Core positioning and technical principle
Technology type: Digital Coherent Optical (DCO)
By using coherent detection (polarization multiplexing + high-order modulation) and digital signal processing (DSP) technology, it significantly improves transmission distance and spectral efficiency.
Application scenarios: Metropolitan Area Network (MAN), backbone network, data center interconnection (DCI), etc. (for medium to long-distance transmission: 80km to 2000km+).
Compared with AOC: Completely different from short-range AOC (such as FTLC3321X3NL), specifically designed for high-capacity links over 100km.
2. Key performance parameters
Feature specifications:
Packaging: CFP2 (hot-swappable, supports high-density deployment)
Rate: 200Gbps (supports flexible rate configuration: 100G/150G/200G)
Modulation format: DP-16QAM (dual-polarization 16-bit quadrature amplitude modulation) or DP-QPSK (adapted according to distance)
Wavelength: C-band (1530~1565nm), supports tunable laser (ITLA)
Transmission distance: 80km to 2000km+ (depending on modulation format and fiber conditions)
Fiber type: Single-mode fiber (SMF, G.652 standard)
Power consumption: Typical value ≤ 24W (including DSP power consumption, requires strong heat dissipation design)
Interface: Host side: CFP2 electrical interface (4×50G PAM4) <br>- Optical side: Dual LC/APC connectors
3. Core technical advantages
Ultra-long-distance transmission capability
Through coherent receiving technology to compensate for fiber dispersion (CD) and polarization mode dispersion (PMD), it breaks through the distance limitation of traditional direct modulation modules.
Adaptive modulation:
DP-16QAM: Suitable for 80~500km (high-capacity medium-range scenarios)
DP-QPSK: Suitable for 500~2000km+ (ultra-long-range scenarios, sacrificing rate for distance)
Spectrum efficiency doubling
16QAM spectral efficiency reaches 8bit/s/Hz (8 times that of traditional 10G direct modulation technology), single wavelength can transmit 200G, reducing fiber resource occupation.
Integrated DSP chip
Real-time processing functions: carrier phase recovery (CPR), forward error correction (FEC, such as OFEC/CFEC), nonlinear damage compensation (NLC)
. Application scenarios
Data center interconnection (DCI): Cross-organizational/city-level data centers (≤120km, using 16QAM).
Metropolitan/ backbone network transmission: Operator core network (200~2000km, using QPSK).
Undersea optical cable system: Ultra-long-distance high-capacity transmission (requires relay equipment).
4. Deployment requirements
1. Cooling: The air duct design of the equipment must meet the ≥24W cooling requirement.
2. Compatibility: The host equipment must support CFP2-DCO slot and coherent DSP algorithm (such as OpenROADM standard).
3. Fiber link: Single-mode fiber + G.652 standard, control link loss and nonlinear effects.
