Cisco · Optical Transceivers & SFP

Cisco GLC and SFP-10G optical transceivers

Cisco optics are the most searched-for part numbers in the Gulf among everything we track, and for a simple reason: every enterprise, ISP and operator core in the region has Cisco switching somewhere, and every one of those switches needs pluggables that are rarely bought with the chassis. The enquiries are precise — a buyer with a bill of materials asks for GLC-SX-MMD by quantity, not for 'a gigabit SFP'. This page lists the GLC, SFP-10G, SFP-25G, QSFP-40G and QSFP-100G families we source, plus the copper and optical cables that go with them.

How to read these part numbers

Cisco's naming carries the specification. GLC- prefixes gigabit SFPs, with SX, LH, EX and ZX giving reach class (550 m, 10 km, 40 km, 80 km), T and TE for copper, FE for 100 Mbit/s, and BX for single-fibre bidirectional pairs that must be ordered as U and D ends. A trailing D — GLC-SX-MMD — means digital optical monitoring; the older no-D codes are functionally similar but end-of-sale. SFP-10G- prefixes 10 Gbit/s SFP+ with SR, LR, ER and ZR reach classes; the -S suffix is the enterprise-class variant without extended temperature and is the one most buyers actually want. RGD, -X and -I suffixes denote industrial temperature. QSFP-40G and QSFP-100G follow the same logic with SR4, LR4, CWDM4 and BiDi reach classes.

Ordering notes

Quote the exact Cisco part number including suffix — SFP-10G-SR and SFP-10G-SR-S price differently and are not the same item. Give the platform and IOS / NX-OS release, since Cisco checks vendor coding at the port and will reject an unsupported module. State whether you require genuine Cisco or will accept a Cisco-coded compatible module; we quote both and mark which is which, never one as the other. For BiDi optics order U and D ends as a pair. For DACs and AOCs give the exact length. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

Lifecycle and availability

Current GLC-*D, SFP-10G-*-S, SFP-25G and QSFP-100G families remain in production and are sourced new. Legacy no-D GLC codes, SFP-10G-LRM and older 40G optics are end-of-sale and increasingly surplus-only. Optics are the most counterfeited category in the secondary market; we source through verifiable channels and state the origin of every module on the quotation. CRS PLUS is an independent broker and is not an authorised Cisco partner.

Equipment condition

New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.

New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.

Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.

Condition is confirmed in writing on every quotation before you commit to an order.

Warranty

Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.

Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.

Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.

Frequently asked questions

Same optical specification, different class. The -S variant is the enterprise and data-centre version without extended temperature support and is normally the cheaper of the two. Most enterprise buyers want -S; tell us which you have specified.

Manufacturer names, product names and part numbers are the property of their respective owners and are used here for identification purposes only. CRS PLUS sources these products through its verified supplier network and is not an authorised distributor or agent for any manufacturer listed.

This catalogue is compiled from our supplier network's available inventory and from manufacturer product documentation, and is reviewed monthly. Listing does not indicate stock held by CRS PLUS — availability, condition and lead time are confirmed per enquiry. Last reviewed: 22 August 2026.
