Introduction to the product and its key features
Hikvision HK‑SFP‑1.25G‑1310‑DF‑MMis a compact, hot‑swappable SFP (small form‑factor pluggable) optical transceiver designed for short‑range multimode fibre links. Engineered primarily for CCTV/surveillance uplinks, switch‑to‑switch links and media‑converter connections, this module supports 1.25 Gbps Ethernet over duplex multimode fibre with LC connectors and a typical reach of up to 1 km. It operates from a single 3.3 V supply, is MSA‑compatible and RoHS compliant, making it a straightforward, low‑cost option for upgrading or extending fibre connectivity in many small to medium network deployments.
- Hot‑pluggable SFP (MSA) form factor for easy on‑site replacement and upgrades.
- 1.25 Gbps data rate — reliable performance for legacy gigabit links and many CCTV systems.
- Duplex LC connector compatible with standard multimode fibres (50/125 & 62.5/125 µm).
- 1310 nm Tx/Rx wavelength with up to 1 km reach over MMF — suitable for campus and short‑range metro links.
- Wide operating conditions (0 °C to 70 °C) for typical indoor and some sheltered outdoor environments.
At a suggested retail price of around $24.99 (cost price example: $15.17), the HK‑SFP‑1.25G‑1310‑DF‑MM sits in the entry‑to‑mid range for multimode SFP modules. For installers and organisations needing economical fibre links for surveillance, access network uplinks or media conversion, the module delivers a good balance of cost, compatibility and proven SFP convenience.

- Multimode LC duplex:Works with commonly installed multimode cabling in buildings and campuses, avoiding costly re‑cabling to singlemode when distances are within 1 km.
- 1310 nm operation over MMF:Provides a clean balance between performance and cost for short‑ to medium‑range applications where dispersion at higher wavelengths is manageable.
- Environmental tolerance:The 0–70 °C operating range covers most indoor and climate‑controlled outdoor enclosures, while storage limits provide resilience during transport and staging.
- Regulatory considerations:RoHS compliance ensures adherence to common environmental standards; however, users should verify CE/UKCA or other market‑specific certifications if required.
Use cases and scenarios where the product excels
The HK‑SFP‑1.25G‑1310‑DF‑MM is purposefully suited to applications that require reliable, short‑range multimode fibre connectivity without the need for higher‑speed transceivers. Typical scenarios include:
- Many IP camera systems or video management setups use 1.25 Gbps uplinks from remote PoE switches to aggregation switches. This SFP fits those uplinks cost‑effectively, especially when distances are within 1 km of fibre.
- Interbuilding links between classrooms, administrative buildings and dorms where multimode fibre is already installed. The module simplifies upgrades from copper or older modules to standardized SFP links.
- Media converters that bridge copper Ethernet to multimode fibre commonly accept standard SFPs. This Hikvision SFP is suitable for these converters in scenarios where speeds and distances match its capabilities.
- Because it is hot‑pluggable and inexpensive relative to higher‑speed optics, the module is handy for temporary links, site testing and staged installations where cost control is important.
Comparisons with similar products in the market
When choosing an SFP module, buyers often compare price, reach, wavelength compatibility, vendor interoperability and environmental ratings. Below are the main points of comparison between the HK‑SFP‑1.25G‑1310‑DF‑MM and alternative options.
- Performance and specifications are broadly similar across many manufacturers for short‑reach 1.25 Gb multimode SFPs: same form factor, LC duplex, and ~1 km reach at 1310 nm. Differences typically arise in firmware lock‑in policies, vendor compatibility warnings and warranty terms.
- Hikvision’s module offers common industry specs at a competitive suggested price, making it an economical choice where vendor verification with host devices has been performed.
- Copper SFPs are convenient where fibre isn’t present, but fibre offers better electromagnetic immunity, longer distances and future scalability. If your environment requires isolated links or crosses noisy electrical areas, the optical SFP has clear advantages.
- Singlemode SFPs typically support much longer distances but require singlemode fibre and are costlier. SFP+ (10 Gb) modules are for much higher throughput and require SFP+ compatible ports and cabling. The Hikvision 1.25 Gb multimode SFP is a good fit where singlemode or 10 Gb capacity is unnecessary.
- Some network equipment vendors implement firmware checks that block or flag third‑party modules. Before purchasing, verify that your switch, DVR or converter accepts third‑party SFPs, or choose equipment with known compatibility lists. In many practical deployments, third‑party SFPs like Hikvision’s work without issue when the host accepts MSA‑compliant optics.
Customer testimonials or reviews
Official third‑party customer reviews for this specific Hikvision SFP were not supplied in the datasheet provided. That said, common feedback themes from professional installers and IT teams using comparable 1.25 Gb multimode SFPs are useful to consider:
- "Reliable for CCTV uplinks" — Installers often note stable video streams when using 1.25 Gb multimode SFPs for camera aggregation, provided connections and fibre condition are good.
- "Good value for money" — Many small IT teams appreciate the lower unit price for short‑reach optics compared with singlemode or higher‑speed alternatives.
- "Check compatibility with switches" — Some users report host devices that block non‑OEM modules; buyers recommend validating compatibility or testing a single unit before bulk purchases.
- "Easy field replacement" — Hot‑swappable SFPs are praised for reducing downtime during maintenance windows.
If you require verified user reviews, consider checking reseller sites, professional forums or asking the manufacturer for case studies relevant to your industry.
Conclusion: why this product is a great choice
The Hikvision HK‑SFP‑1.25G‑1310‑DF‑MM is a practical, cost‑conscious optical transceiver for organisations that need dependable short‑range multimode fibre links. Its MSA‑compatible SFP form factor, 1.25 Gbps data rate, duplex LC connectors and up to 1 km reach make it particularly well suited to CCTV uplinks, switch interconnects and media‑converter applications where full 10 Gb bandwidth or singlemode reach is not required.
Strengths include low acquisition cost, hot‑swappable convenience and compliance with common environmental regulations (RoHS). Potential buyers should confirm device interoperability for third‑party optics, check any market‑specific certification needs (CE/UKCA where applicable) and handle modules with standard ESD precautions during installation.
Overall, for installers, IT staff and competent DIY networkers looking to maintain or expand multimode fibre links affordably and efficiently, the Hikvision HK‑SFP‑1.25G‑1310‑DF‑MM represents a sensible and practical choice.
