QSFP modules for OLTs vary in price depending on type, data rate, and vendor, with CIF pricing influenced by shipping, customs, and volume.

QSFP Types and Applications in OLTs

QSFP (Quad Small Form-Factor Pluggable) modules are hot-pluggable optical transceivers used in high-speed uplinks for Optical Line Terminals (OLTs) in GPON, XGS-PON, and other fiber networks . Common types include:

• QSFP+: Supports 4×10 Gbps channels, aggregate 40 Gbps, suitable for standard OLT uplinks .
• QSFP28: 4×25 Gbps channels, 100 Gbps aggregate, widely used in modern data centers and high-capacity OLTs .
• QSFP56: 4×50 Gbps channels, 200 Gbps aggregate, using PAM4 modulation for higher bandwidth .
• QSFP-DD: Double-density modules with 8 lanes, supporting 400–800 Gbps, backward compatible with QSFP28, ideal for next-generation OLTs and metro/regional networks . These modules are compatible with OLT uplink ports, such as the DeltaStream 8-Port Combo OLT, which supports 2×40G QSFP+ ports for high-bandwidth connectivity .

Factors Affecting CIF Price

The CIF (Cost, Insurance, and Freight) price of QSFP modules depends on several factors:

1. Module Type and Data Rate: Higher-speed modules like QSFP-DD or QSFP112 cost more than QSFP+ due to advanced silicon photonics and DSP ASICs .
2. Vendor and Brand: Cisco, TE Connectivity, Acacia, and other manufacturers have different pricing based on technology, warranty, and support .
3. Quantity and Volume Discounts: Bulk orders reduce per-unit CIF cost.
4. Shipping and Insurance: CIF includes freight and insurance to the destination port, which varies by distance, carrier, and shipping method.
5. Customs and Import Duties: Local tariffs and taxes affect the final CIF price.

Practical Guidance

• For standard OLT deployments, QSFP+ or QSFP28 modules are cost-effective and widely available.
• For high-capacity or future-proof networks, QSFP56 or QSFP-DD modules provide higher bandwidth but at a higher CIF cost.
• Always request vendor quotations including CIF terms, as prices fluctuate with market demand, silicon shortages, and shipping costs. In summary, while exact CIF prices are not publicly listed, understanding the module type, data rate, vendor, and shipping factors allows network planners to estimate costs and select the appropriate QSFP module for OLT deployments .
