Hardware-Specific Coding: Tell us your switch environment. Our optical technicians custom-program the EEPROM for seamless plug-and-play deployment in high-density aggregation layers.
Product Overview
As enterprise data centers outgrow 10G capacities, upgrading to 25G requires optical transceivers that match exact infrastructural tolerances. Standard off-the-shelf short-reach modules often struggle with signal distortion in highly dense, noisy switch environments. The Wolon Custom 25GBASE-SR SFP28 MODULE provides a perfectly tailored 25Gbps solution. We custom-tune the multimode VCSEL laser arrays and integrate advanced DSP chips to actively clean the high-speed data stream. By building these transceivers to your precise operational parameters, we ensure a seamless, error-free evolution for your core network.
Key Features
-
Custom Firmware Coding: Eliminates "unsupported transceiver" errors by matching the exact proprietary handshake protocols required by your specific network hardware.
-
Thermal-Optimized Design: We set the warning and alarm thresholds for temperature and optical power specifically to your facility's operational baselines.
-
Rigorous QA Testing: Established in 2010, Wolon subjects every custom SFP28 MODULE to strict bit-error-rate and target-device compatibility testing before leaving our production floor.

Frequently Asked Questions
Q1: Since this is a 25G data rate, is OM4 fiber strictly mandatory, or can we use existing OM3?
A: For Top-of-Rack (ToR) interconnects, standard OM4 multimode fiber will provide a flawless, zero-packet-loss reach of up to 100 meters. However, if your facility is leveraging existing OM3 fiber pathways, our 25GBASE-SR module still delivers a highly stable 25Gbps connection for up to 70 meters.
Q2: Does this 25G SR module feature built-in Clock and Data Recovery (CDR)?
A: Yes. As an enterprise-grade module, it is equipped with dual CDR chips on both the transmitter (TX) and receiver (RX) channels to ensure ultra-low jitter and supreme signal integrity at 25Gbps. For extremely short DAC/AOC links, we also support custom EEPROM coding to bypass the CDR, further reducing power consumption.
Q3: We have a mix of switch brands in our data center. How do you guarantee compatibility?
A: Backed by our 3 specialized factories in Wuhan and a workforce of 400-500 industry experts, we maintain a comprehensive testing lab with all mainstream switches. Every SFP28 MODULE undergoes bespoke EEPROM coding and live-traffic verification against your target hardware (e.g., Cisco, Arista, Juniper) before it ever leaves our facility.
Q4: Is the Forward Error Correction (FEC) enabled on the module or the host switch?
A: FEC is enabled on your host 25G switch. Our 25GBASE-SR hardware fully supports and passes through the RS-FEC protocol. Enabling it on the switch significantly enhances link fault tolerance and overall stability.
