I. Product Description
Finisar FTLX8573D3BTL: This is the manufacturer's specific model code, used to uniquely identify this product.
10GBase-SR: This indicates the protocol standard. It is an IEEE-defined standard used to achieve a 10Gbps data transmission rate over multimode optical fibers.
SFP+: This is its packaging form. SFP+ is an enhanced small form-factor pluggable module,
with dimensions and interfaces that are industry standards, and can be hot-plugged into switches, routers, or network cards that support SFP+ ports.
MMF: The medium type is multimode fiber. This corresponds to the 10GBase-SR standard and must be used in conjunction with multimode fiber.
850nm: This is the wavelength used when it operates. 850 nanometers is a short wavelength, typically used for multi-mode fiber transmission.
300m: This is its maximum transmission distance. On standard OM3 multi-mode fiber, it can support the longest transmission of 300 meters.
If using a higher-quality OM4 fiber, the distance can be extended to 400 meters or even further.
LC: This is the type of fiber connector. LC is a small square duplex connector, currently the most mainstream and common fiber interface.
DOM: Digital Diagnostic Monitoring. This is an important feature of the module.
It means that the module has sensors that can be monitored in real-time by network devices supporting DOM functions (such as switches), such as:
Transmitted optical power, received optical power, supply voltage, laser bias current, module temperature,
and the DOM function is crucial for network operation, fault diagnosis, and early warning.
Summary of core specifications:
Rate: 10.3125 Gbps (10 Gigabit Ethernet)
Interface: LC duplex (one fiber for transmission Tx, one for reception Rx)
Optical fiber type: OM2, OM3, OM4 multi-mode fiber
Maximum distance: 300m (OM3), 400m (OM4)
Power consumption: Typical value is below 1W
Commercial temperature range: 0°C to 70°C
II. Usage scenarios
This optical module is mainly used for scenarios requiring short-distance, high-speed data connections,
1. Data center internal connections:
Connections between top-of-rack (ToR) switches and aggregation/core layer switches.
High-speed access between servers (equipped with SFP+ network cards) and ToR switches.
Connections between storage devices (such as SAN) and network switches.
2. Enterprise networks and campus networks:
Fiber backbone connections between buildings within an office or in a campus. A distance of 300-400 meters is usually sufficient to cover most campus environments.
High-speed interconnection between core switches and distribution frame switches in enterprise data centers.
3. High-performance computing (HPC) clusters:
Connecting computing nodes in the cluster to meet low-latency, high-bandwidth communication requirements.
4. Any device that supports SFP+ ports and has a transmission distance of 300 meters or less for interconnection.
III. Compatibility considerations
Fiber must match: Must use multi-mode fiber (OM3 or OM4 is preferred). If mistakenly used on single-mode fiber, communication will not occur or the module may be damaged.
Fiber jumper type: Requires LC-LC interface duplex multi-mode fiber jumpers.
Wavelength matching: Although 850nm is the standard, it is necessary to ensure that the modules at both ends are matched (i.e., both use SR modules with 850nm wavelength).
Compatibility: Finisar original modules are usually compatible with mainstream network equipment brands (such as Cisco, Juniper, HPE Aruba,
Dell) HUAWEI, H3C, etc. have good compatibility. However, on some devices, specific instructions or flashing the corresponding firmware code may be required to pass the compatibility check.
4. Differences from similar products
vs 10GBase-LR: The LR module uses single-mode fiber and a 1310nm wavelength, with a transmission distance of up to 10 kilometers.
However, both the module and the fiber cost are higher. SR is used for short distances and has a lower cost.
vs 1000Base-SX: This is a 1Gbps (gigabit) multimode fiber module, with a rate one-tenth that of FTLX8571D3BTL, and the transmission distance is similar.
