The S series fixed Ethernet switches integrate the access and transmission functions to provide reliable access/aggregation and high-quality transmission of services on enterprise networks. The switches are built on an integrated hardware platform, and their hardware system consists of the chassis, power module, fan module, extended cards, and Switch Control Unit (SCU).
The Huawei S5735S-L24FT4S-A is a high-performance, cost-effective, balanced all-optical PoE 10 Gigabit switch from the Huawei S5735S series. Its core advantage is "economical and efficient all-optical PoE networking for small and medium-sized scenarios"—24 Gigabit optical ports support 1200-2500 terminals, with a maximum power supply of 30W per port and a total power budget of ≥510W, supporting long-distance transmission of ≤20km; 4 10 Gigabit optical ports support high-speed uplink, and the fiber optic medium resists electromagnetic interference; the total switching capacity is ≥598Gbps, the forwarding performance reaches 96Mpps, and it supports basic full-featured functions such as ACL and QoS. It is the core choice for small and medium-sized enterprises and campuses with long-distance access that "balances long-distance, anti-interference, and power supply stability".
S5735S-L24FT4S-A FAQ
Q1: What is the core difference between this model and the S5735S-L24P4S-A (Electronic PoE version) in the same series?
A1: The former is an all-optical PoE model (optical port access + long-distance transmission + anti-interference), while the latter is an electrical PoE model (short-distance copper cable access). For long-distance deployments and complex electromagnetic environments, the former is the preferred choice.
Q2: Can the transmission distance of the optical PoE meet the needs of small to medium-sized campuses spanning multiple buildings?
A2: Yes, it can achieve ≤20km long-distance power supply and data transmission with single-mode fiber, fully meeting the long-distance networking needs of 3-5 buildings without the need for additional repeater equipment.
Q3: Is it compatible with non-Huawei optical modules and third-party PoE devices (such as Dahua long-distance cameras)?
A3: Fully compatible with IEEE 802.3af/at/bt standards and general SFP/SFP+ optical modules. PoE devices and optical modules from different brands can be seamlessly connected without additional adaptation and debugging.
